dnl Hardening flags
dnl
dnl The prime control of whether to apply (targeted) hardening build flags and
dnl which ones is --{enable,disable}-hardening option passed to ./configure:
dnl
dnl --enable-hardening=try (default):
dnl depending on whether any of CFLAGS_HARDENED_EXE, LDFLAGS_HARDENED_EXE,
dnl CFLAGS_HARDENED_LIB or LDFLAGS_HARDENED_LIB environment variables
dnl (see below) is set and non-null, all these custom flags (even if not
dnl set) are used as are, otherwise the best effort is made to offer
dnl reasonably strong hardening in several categories (RELRO, PIE,
dnl "bind now", stack protector) according to what the selected toolchain
dnl can offer
dnl
dnl --enable-hardening:
dnl same effect as --enable-hardening=try when the environment variables
dnl in question are suppressed
dnl
dnl --disable-hardening:
dnl do not apply any targeted hardening measures at all
dnl
dnl The user-injected environment variables that regulate the hardening in
dnl default case are as follows:
dnl
dnl * CFLAGS_HARDENED_EXE, LDFLAGS_HARDENED_EXE
dnl compiler and linker flags (respectively) for daemon programs
dnl (pacemakerd, pacemaker-attrd, pacemaker-controld, pacemaker-execd,
dnl cib, stonithd, pacemaker-remoted, pacemaker-schedulerd)
dnl
dnl * CFLAGS_HARDENED_LIB, LDFLAGS_HARDENED_LIB
dnl compiler and linker flags (respectively) for libraries linked
dnl with the daemon programs
dnl
dnl Note that these are purposedly targeted variables (addressing particular
dnl targets all over the scattered Makefiles) and have no effect outside of
dnl the predestined scope (e.g., CLI utilities). For a global reach,
dnl use CFLAGS, LDFLAGS, etc. as usual.
dnl
dnl For guidance on the suitable flags consult, for instance:

Installation
------------
Install |CFS_DISTRO| |CFS_DISTRO_VER|
################################################################################################
Boot the Install Image
______________________
Download the 4GB |CFS_DISTRO| |CFS_DISTRO_VER| `DVD ISO <http://isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1804.iso>`_.
Use the image to boot a virtual machine, or burn it to a DVD or USB drive and
boot a physical server from that.
After starting the installation, select your language and keyboard layout at
the welcome screen.

Installation Options
____________________
At this point, you get a chance to tweak the default installation options.

|CFS_DISTRO| |CFS_DISTRO_VER| Installation Summary Screen
Ignore the **SOFTWARE SELECTION** section (try saying that 10 times quickly). The
**Infrastructure Server** environment does have add-ons with much of the software
we need, but we will leave it as a **Minimal Install** here, so that we can see
exactly what software is required later.
Configure Network
_________________
In the **NETWORK & HOSTNAME** section:
- Edit **Host Name:** as desired. For this example, we will use
**pcmk-1.localdomain**.
- Select your network device, press **Configure...**, and manually assign a fixed
IP address. For this example, we'll use 192.168.122.101 under **IPv4 Settings**
(with an appropriate netmask, gateway and DNS server).
- Flip the switch to turn your network device on, and press **Done**.

|CFS_DISTRO| |CFS_DISTRO_VER| Network Interface Screen
.. IMPORTANT::
Do not accept the default network settings.
Cluster machines should never obtain an IP address via DHCP, because
DHCP's periodic address renewal will interfere with corosync.
Configure Disk
______________
By default, the installer's automatic partitioning will use LVM (which allows
us to dynamically change the amount of space allocated to a given partition).
However, it allocates all free space to the ``/`` (aka. **root**) partition, which
cannot be reduced in size later (dynamic increases are fine).
In order to follow the DRBD and GFS2 portions of this guide, we need to reserve
space on each machine for a replicated volume.
Enter the **INSTALLATION DESTINATION** section, ensure the hard drive you want to
install to is selected, select **I will configure partitioning**, and press **Done**.
In the **MANUAL PARTITIONING** screen that comes next, click the option to create
mountpoints automatically. Select the ``/`` mountpoint, and reduce the desired
capacity by 1GiB or so. Select **Modify...** by the volume group name, and change
the **Size policy:** to **As large as possible**, to make the reclaimed space
available inside the LVM volume group. We'll add the additional volume later.

Press **Done**, then **Accept changes**.
Configure Time Synchronization
______________________________
It is highly recommended to enable NTP on your cluster nodes. Doing so
ensures all nodes agree on the current time and makes reading log files
significantly easier.
|CFS_DISTRO| will enable NTP automatically. If you want to change any time-related
settings (such as time zone or NTP server), you can do this in the
**TIME & DATE** section.
Finish Install
______________
Select **Begin Installation**. Once it completes, set a root password, and reboot
as instructed. For the purposes of this document, it is not necessary to create
any additional users. After the node reboots, you'll see a login prompt on
the console. Login using **root** and the password you created earlier.

Configure the OS
################
Verify Networking
_________________
Ensure that the machine has the static IP address you configured earlier.
.. code-block:: none
[root@pcmk-1 ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft forever preferred_lft forever
inet6 fe80::e45:c99b:34c0:c657/64 scope link noprefixroute
valid_lft forever preferred_lft forever
.. NOTE::
If you ever need to change the node's IP address from the command line, follow
these instructions, replacing **${device}** with the name of your network device:
.. code-block:: none
[root@pcmk-1 ~]# vi /etc/sysconfig/network-scripts/ifcfg-${device} # manually edit as desired
[root@pcmk-1 ~]# nmcli dev disconnect ${device}
[root@pcmk-1 ~]# nmcli con reload ${device}
[root@pcmk-1 ~]# nmcli con up ${device}
This makes **NetworkManager** aware that a change was made on the config file.
Next, ensure that the routes are as expected:
.. code-block:: none
[root@pcmk-1 ~]# ip route
default via 192.168.122.1 dev eth0 proto static metric 100
192.168.122.0/24 dev eth0 proto kernel scope link src 192.168.122.101 metric 100
If there is no line beginning with **default via**, then you may need to add a line such as
``GATEWAY="192.168.122.1"``
to the device configuration using the same process as described above for
changing the IP address.
Now, check for connectivity to the outside world. Start small by
testing whether we can reach the gateway we configured.
.. code-block:: none
[root@pcmk-1 ~]# ping -c 1 192.168.122.1
PING 192.168.122.1 (192.168.122.1) 56(84) bytes of data.

Login Remotely
______________
The console isn't a very friendly place to work from, so we will now
switch to accessing the machine remotely via SSH where we can
use copy and paste, etc.
From another host, check whether we can see the new host at all:
.. code-block:: none
beekhof@f16 ~ # ping -c 1 192.168.122.101
PING 192.168.122.101 (192.168.122.101) 56(84) bytes of data.

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.012/1.012/1.012/0.000 ms
Next, login as root via SSH.
.. code-block:: none
beekhof@f16 ~ # ssh -l root 192.168.122.101
The authenticity of host '192.168.122.101 (192.168.122.101)' can't be established.
ECDSA key fingerprint is 6e:b7:8f:e2:4c:94:43:54:a8:53:cc:20:0f:29:a4:e0.

Apply Updates
_____________
Apply any package updates released since your installation image was created:
.. code-block:: none
[root@pcmk-1 ~]# yum update
.. index::
single: node; short name
Use Short Node Names
____________________
During installation, we filled in the machine's fully qualified domain
name (FQDN), which can be rather long when it appears in cluster logs and
status output. See for yourself how the machine identifies itself:
.. code-block:: none
[root@pcmk-1 ~]# uname -n
pcmk-1.localdomain
We can use the `hostnamectl` tool to strip off the domain name:
.. code-block:: none
[root@pcmk-1 ~]# hostnamectl set-hostname $(uname -n | sed s/\\..*//)
Now, check that the machine is using the correct name:
.. code-block:: none
[root@pcmk-1 ~]# uname -n
pcmk-1
You may want to reboot to ensure all updates take effect.
Repeat for Second Node
######################
Repeat the Installation steps so far, so that you have two
nodes ready to have the cluster software installed.
For the purposes of this document, the additional node is called
pcmk-2 with address 192.168.122.102.
Configure Communication Between Nodes
#####################################
Configure Host Name Resolution
______________________________
Confirm that you can communicate between the two new nodes:
.. code-block:: none
[root@pcmk-1 ~]# ping -c 3 192.168.122.102
PING 192.168.122.102 (192.168.122.102) 56(84) bytes of data.
64 bytes from 192.168.122.102: icmp_seq=1 ttl=64 time=0.343 ms
64 bytes from 192.168.122.102: icmp_seq=2 ttl=64 time=0.402 ms
64 bytes from 192.168.122.102: icmp_seq=3 ttl=64 time=0.558 ms
--- 192.168.122.102 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2000ms
rtt min/avg/max/mdev = 0.343/0.434/0.558/0.092 ms
Now we need to make sure we can communicate with the machines by their
name. If you have a DNS server, add additional entries for the two
machines. Otherwise, you'll need to add the machines to ``/etc/hosts``
on both nodes. Below are the entries for my cluster nodes:
.. code-block:: none
[root@pcmk-1 ~]# grep pcmk /etc/hosts
192.168.122.101 pcmk-1.clusterlabs.org pcmk-1
192.168.122.102 pcmk-2.clusterlabs.org pcmk-2
We can now verify the setup by again using ping:
.. code-block:: none
[root@pcmk-1 ~]# ping -c 3 pcmk-2
PING pcmk-2.clusterlabs.org (192.168.122.101) 56(84) bytes of data.

Configure SSH
_____________
SSH is a convenient and secure way to copy files and perform commands
remotely. For the purposes of this guide, we will create a key without a
password (using the -N option) so that we can perform remote actions
without being prompted.
.. WARNING::
Unprotected SSH keys (those without a password) are not recommended for
servers exposed to the outside world. We use them here only to simplify
the demo.
Create a new key and allow anyone with that key to log in:

Controlling Command Line Output
###############################
Some of the pacemaker command line utilities have been converted to a new
output system. Among these tools are ``crm_mon`` and ``stonith_admin``. This
is an ongoing project, and more tools will be converted over time. This system
lets you control the formatting of output with ``--output-as=`` and the
destination of output with ``--output-to=``.
The available formats vary by tool, but at least plain text and XML are
supported by all tools that use the new system. The default format is plain
text. The default destination is stdout but can be redirected to any file.
Some formats support command line options for changing the style of the output.
For instance:
.. code-block:: none
# crm_mon --help-output
Usage:
crm_mon [OPTION?]
Provides a summary of cluster's current state.
Outputs varying levels of detail in a number of different formats.
Output Options:
--output-as=FORMAT Specify output format as one of: console (default), html, text, xml
--output-to=DEST Specify file name for output (or "-" for stdout)
--html-cgi Add text needed to use output in a CGI program
--html-stylesheet=URI Link to an external CSS stylesheet
--html-title=TITLE Page title
--text-fancy Use more highly formatted output

Monitor a Cluster with crm_mon
##############################
The ``crm_mon`` utility displays the current state of an active cluster. It can
show the cluster status organized by node or by resource, and can be used in
either single-shot or dynamically updating mode. It can also display operations
performed and information about failures.
Using this tool, you can examine the state of the cluster for irregularities,
and see how it responds when you cause or simulate failures.
See the manual page or the output of ``crm_mon --help`` for a full description
of its many options.

As mentioned in an earlier chapter, the DC is the node is where decisions are
made. The cluster elects a node to be DC as needed. The only significance of
the choice of DC to an administrator is the fact that its logs will have the
most information about why decisions were made.

.. _crm_mon_css:
Styling crm_mon HTML output
___________________________
Various parts of ``crm_mon``'s HTML output have a CSS class associated with
them. Not everything does, but some of the most interesting portions do. In
the following example, the status of each node has an ``online`` class and the
details of each resource have an ``rsc-ok`` class.
.. code-block:: html
<h2>Node List</h2>
<ul>
<li>
<span>Node: cluster01</span><span class="online"> online</span>
</li>
<li><ul><li><span class="rsc-ok">ping (ocf::pacemaker:ping): Started</span></li></ul></li>
<li>
<span>Node: cluster02</span><span class="online"> online</span>
</li>
<li><ul><li><span class="rsc-ok">ping (ocf::pacemaker:ping): Started</span></li></ul></li>
</ul>
By default, a stylesheet for styling these classes is included in the head of
the HTML output. The relevant portions of this stylesheet that would be used
in the above example is:
.. code-block:: css
<style>
.online { color: green }
.rsc-ok { color: green }
</style>
If you want to override some or all of the styling, simply create your own
stylesheet, place it on a web server, and pass ``--html-stylesheet=<URL>``
to ``crm_mon``. The link is added after the default stylesheet, so your
changes take precedence. You don't need to duplicate the entire default.
Only include what you want to change.

.. _cibadmin:
Edit the CIB XML with cibadmin
##############################
The most flexible tool for modifying the configuration is Pacemaker's
``cibadmin`` command. With ``cibadmin``, you can query, add, remove, update
or replace any part of the configuration. All changes take effect immediately,
so there is no need to perform a reload-like operation.
The simplest way of using ``cibadmin`` is to use it to save the current
configuration to a temporary file, edit that file with your favorite
text or XML editor, and then upload the revised configuration.
.. topic:: Safely using an editor to modify the cluster configuration
.. code-block:: none
# cibadmin --query > tmp.xml
# vi tmp.xml
# cibadmin --replace --xml-file tmp.xml
Some of the better XML editors can make use of a RELAX NG schema to
help make sure any changes you make are valid. The schema describing
the configuration can be found in ``pacemaker.rng``, which may be
deployed in a location such as ``/usr/share/pacemaker`` depending on your
operating system distribution and how you installed the software.
If you want to modify just one section of the configuration, you can
query and replace just that section to avoid modifying any others.
.. topic:: Safely using an editor to modify only the resources section
.. code-block:: none
# cibadmin --query --scope resources > tmp.xml
# vi tmp.xml
# cibadmin --replace --scope resources --xml-file tmp.xml
To quickly delete a part of the configuration, identify the object you wish to
delete by XML tag and id. For example, you might search the CIB for all
STONITH-related configuration:
.. topic:: Searching for STONITH-related configuration items
.. code-block:: none
# cibadmin --query | grep stonith
<nvpair id="cib-bootstrap-options-stonith-action" name="stonith-action" value="reboot"/>
<nvpair id="cib-bootstrap-options-stonith-enabled" name="stonith-enabled" value="1"/>
<primitive id="child_DoFencing" class="stonith" type="external/vmware">
<lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:1" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:2" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:0" type="external/vmware" class="stonith">
<lrm_resource id="child_DoFencing:3" type="external/vmware" class="stonith">
If you wanted to delete the ``primitive`` tag with id ``child_DoFencing``,
you would run:
.. code-block:: none
# cibadmin --delete --xml-text '<primitive id="child_DoFencing"/>'
See the cibadmin man page for more options.
.. warning::
Never edit the live ``cib.xml`` file directly. Pacemaker will detect such
changes and refuse to use the configuration.

single: crm_shadow
single: command-line tool; crm_shadow
.. _crm_shadow:
Batch Configuration Changes with crm_shadow
###########################################
Often, it is desirable to preview the effects of a series of configuration
changes before updating the live configuration all at once. For this purpose,
``crm_shadow`` creates a "shadow" copy of the configuration and arranges for
all the command-line tools to use it.
To begin, simply invoke ``crm_shadow --create`` with a name of your choice,
and follow the simple on-screen instructions. Shadow copies are identified with
a name to make it possible to have more than one.
.. warning::
Read this section and the on-screen instructions carefully; failure to do so
could result in destroying the cluster's active configuration!
.. topic:: Creating and displaying the active sandbox
.. code-block:: none
# crm_shadow --create test
Setting up shadow instance
Type Ctrl-D to exit the crm_shadow shell
shadow[test]:
shadow[test] # crm_shadow --which
test
From this point on, all cluster commands will automatically use the shadow copy
instead of talking to the cluster's active configuration. Once you have
finished experimenting, you can either make the changes active via the
``--commit`` option, or discard them using the ``--delete`` option. Again, be
sure to follow the on-screen instructions carefully!
For a full list of ``crm_shadow`` options and commands, invoke it with the
``--help`` option.
.. topic:: Use sandbox to make multiple changes all at once, discard them, and verify real configuration is untouched

See the next section, :ref:`crm_simulate`, for how to test your changes before
committing them to the live cluster.
.. index::
single: crm_simulate
single: command-line tool; crm_simulate
.. _crm_simulate:
Simulate Cluster Activity with crm_simulate
###########################################
The command-line tool `crm_simulate` shows the results of the same logic
the cluster itself uses to respond to a particular cluster configuration and
status.
As always, the man page is the primary documentation, and should be consulted
for further details. This section aims for a better conceptual explanation and
practical examples.
Replaying cluster decision-making logic
_______________________________________
At any given time, one node in a Pacemaker cluster will be elected DC, and that
node will run Pacemaker's scheduler to make decisions.
Each time decisions need to be made (a "transition"), the DC will have log
messages like "Calculated transition ... saving inputs in ..." with a file
name. You can grab the named file and replay the cluster logic to see why
particular decisions were made. The file contains the live cluster
configuration at that moment, so you can also look at it directly to see the
value of node attributes, etc., at that time.
The simplest usage is (replacing $FILENAME with the actual file name):
.. topic:: Simulate cluster response to a given CIB
.. code-block:: none
# crm_simulate --simulate --xml-file $FILENAME
That will show the cluster state when the process started, the actions that
need to be taken ("Transition Summary"), and the resulting cluster state if the
actions succeed. Most actions will have a brief description of why they were
required.
The transition inputs may be compressed. ``crm_simulate`` can handle these
compressed files directly, though if you want to edit the file, you'll need to
uncompress it first.
You can do the same simulation for the live cluster configuration at the
current moment. This is useful mainly when using ``crm_shadow`` to create a
sandbox version of the CIB; the ``--live-check`` option will use the shadow CIB
if one is in effect.
.. topic:: Simulate cluster response to current live CIB or shadow CIB
.. code-block:: none
# crm_simulate --simulate --live-check
Why decisions were made
_______________________
To get further insight into the "why", it gets user-unfriendly very quickly. If
you add the ``--show-scores`` option, you will also see all the scores that
went into the decision-making. The node with the highest cumulative score for a
resource will run it. You can look for ``-INFINITY`` scores in particular to
see where complete bans came into effect.
You can also add ``-VVVV`` to get more detailed messages about what's happening
under the hood. You can add up to two more V's even, but that's usually useful
only if you're a masochist or tracing through the source code.
Visualizing the action sequence
_______________________________
Another handy feature is the ability to generate a visual graph of the actions
needed, using the ``--dot-file`` option. This relies on the separate
Graphviz [#]_ project.
.. topic:: Generate a visual graph of cluster actions from a saved CIB
.. code-block:: none
# crm_simulate --simulate --xml-file $FILENAME --dot-file $FILENAME.dot
# dot $FILENAME.dot -Tsvg > $FILENAME.svg
``$FILENAME.dot`` will contain a GraphViz representation of the cluster's
response to your changes, including all actions with their ordering
dependencies.
``$FILENAME.svg`` will be the same information in a standard graphical format
that you can view in your browser or other app of choice. You could, of course,
use other ``dot`` options to generate other formats.
How to interpret the graphical output:
* Bubbles indicate actions, and arrows indicate ordering dependencies
* Resource actions have text of the form
``<RESOURCE>_<ACTION>_<INTERVAL_IN_MS> <NODE>`` indicating that the
specified action will be executed for the specified resource on the
specified node, once if interval is 0 or at specified recurring interval
otherwise
* Actions with black text will be sent to the executor (that is, the
appropriate agent will be invoked)
* Actions with orange text are "pseudo" actions that the cluster uses
internally for ordering but require no real activity
* Actions with a solid green border are part of the transition (that is, the
cluster will attempt to execute them in the given order -- though a
transition can be interrupted by action failure or new events)
* Dashed arrows indicate dependencies that are not present in the transition
graph
* Actions with a dashed border will not be executed. If the dashed border is
blue, the cluster does not feel the action needs to be executed. If the
dashed border is red, the cluster would like to execute the action but
cannot. Any actions depending on an action with a dashed border will not be
able to execute.
* Loops should not happen, and should be reported as a bug if found.

In the above example, it appears that a new node, ``pcmk-2``, has come online
and that the cluster is checking to make sure ``rsc1``, ``rsc2`` and ``rsc3``
are not already running there (indicated by the ``rscN_monitor_0`` entries).
Once it did that, and assuming the resources were not active there, it would
have liked to stop ``rsc1`` and ``rsc2`` on ``pcmk-1`` and move them to
``pcmk-2``. However, there appears to be some problem and the cluster cannot or
is not permitted to perform the stop actions which implies it also cannot
perform the start actions. For some reason, the cluster does not want to start
``rsc3`` anywhere.

What-if scenarios
_________________
You can make changes to the saved or shadow CIB and simulate it again, to see
how Pacemaker would react differently. You can edit the XML by hand, use
command-line tools such as ``cibadmin`` with either a shadow CIB or the
``CIB_file`` environment variable set to the filename, or use higher-level tool
support (see the man pages of the specific tool you're using for how to perform
actions on a saved CIB file rather than the live CIB).
You can also inject node failures and/or action failures into the simulation;
see the ``crm_simulate`` man page for more details.
This capability is useful when using a shadow CIB to edit the configuration.
Before committing the changes to the live cluster with ``crm_shadow --commit``,
you can use ``crm_simulate`` to see how the cluster will react to the changes.

Manage Node Attributes, Cluster Options and Defaults with crm_attribute and attrd_updater
#########################################################################################
``crm_attribute`` and ``attrd_updater`` are confusingly similar tools with subtle
differences.
``attrd_updater`` can query and update node attributes. ``crm_attribute`` can query
and update not only node attributes, but also cluster options, resource
defaults, and operation defaults.
To understand the differences, it helps to understand the various types of node
attribute.
.. table:: **Types of Node Attributes**
+-----------+----------+-------------------+------------------+----------------+----------------+
| Type | Recorded | Recorded in | Survive full | Manageable by | Manageable by |
| | in CIB? | attribute manager | cluster restart? | crm_attribute? | attrd_updater? |
| | | memory? | | | |
+===========+==========+===================+==================+================+================+
| permanent | yes | no | yes | yes | no |
+-----------+----------+-------------------+------------------+----------------+----------------+
| transient | yes | yes | no | yes | yes |
+-----------+----------+-------------------+------------------+----------------+----------------+
| private | no | yes | no | no | yes |
+-----------+----------+-------------------+------------------+----------------+----------------+
As you can see from the table above, ``crm_attribute`` can manage permanent and
transient node attributes, while ``attrd_updater`` can manage transient and
private node attributes.
The difference between the two tools lies mainly in *how* they update node
attributes: ``attrd_updater`` always contacts the Pacemaker attribute manager
directly, while ``crm_attribute`` will contact the attribute manager only for
transient node attributes, and will instead modify the CIB directly for
permanent node attributes (and for transient node attributes when unable to
contact the attribute manager).
By contacting the attribute manager directly, ``attrd_updater`` can change
an attribute's "dampening" (whether changes are immediately flushed to the CIB
or after a specified amount of time, to minimize disk writes for frequent
changes), set private node attributes (which are never written to the CIB), and
set attributes for nodes that don't yet exist.
By modifying the CIB directly, ``crm_attribute`` can set permanent node
attributes (which are only in the CIB and not managed by the attribute
manager), and can be used with saved CIB files and shadow CIBs.
However a transient node attribute is set, it is synchronized between the CIB
and the attribute manager, on all nodes.

Resource Constraints
--------------------
.. index::
single: resource; score
single: node; score
Scores
######
Scores of all kinds are integral to how the cluster works.
Practically everything from moving a resource to deciding which
resource to stop in a degraded cluster is achieved by manipulating
scores in some way.
Scores are calculated per resource and node. Any node with a
negative score for a resource can't run that resource. The cluster
places a resource on the node with the highest score for it.
Infinity Math
_____________
Pacemaker implements **INFINITY** (or equivalently, **+INFINITY**) internally as a
score of 1,000,000. Addition and subtraction with it follow these three basic
rules:
* Any value + **INFINITY** = **INFINITY**
* Any value - **INFINITY** = -**INFINITY**
* **INFINITY** - **INFINITY** = **-INFINITY**
.. note::
What if you want to use a score higher than 1,000,000? Typically this possibility
arises when someone wants to base the score on some external metric that might
go above 1,000,000.
The short answer is you can't.
The long answer is it is sometimes possible work around this limitation
creatively. You may be able to set the score to some computed value based on
the external metric rather than use the metric directly. For nodes, you can
store the metric as a node attribute, and query the attribute when computing
the score (possibly as part of a custom resource agent).
.. _location-constraint:
.. index::
single: location constraint
single: constraint; location
Deciding Which Nodes a Resource Can Run On
##########################################
*Location constraints* tell the cluster which nodes a resource can run on.
There are two alternative strategies. One way is to say that, by default,
resources can run anywhere, and then the location constraints specify nodes
that are not allowed (an *opt-out* cluster). The other way is to start with
nothing able to run anywhere, and use location constraints to selectively
enable allowed nodes (an *opt-in* cluster).
Whether you should choose opt-in or opt-out depends on your
personal preference and the make-up of your cluster. If most of your
resources can run on most of the nodes, then an opt-out arrangement is
likely to result in a simpler configuration. On the other-hand, if
most resources can only run on a small subset of nodes, an opt-in
configuration might be simpler.

Setting ``resource-discovery`` to ``never`` or ``exclusive`` removes Pacemaker's
ability to detect and stop unwanted instances of a service running
where it's not supposed to be. It is up to the system administrator (you!)
to make sure that the service can *never* be active on nodes without
``resource-discovery`` (such as by leaving the relevant software uninstalled).

What if Two Nodes Have the Same Score
_____________________________________
If two nodes have the same score, then the cluster will choose one.
This choice may seem random and may not be what was intended, however
the cluster was not given enough information to know any better.
.. topic:: Constraints where a resource prefers two nodes equally
.. code-block:: xml
<constraints>
<rsc_location id="loc-1" rsc="Webserver" node="sles-1" score="INFINITY"/>

In the example above, assuming no other constraints and an inactive
cluster, **Webserver** would probably be placed on **sles-1** and **Database** on
**sles-2**. It would likely have placed **Webserver** based on the node's
uname and **Database** based on the desire to spread the resource load
evenly across the cluster. However other factors can also be involved
in more complex configurations.

Here is an example of ordering constraints where **Database** *must* start before

started:

<constraints>
<rsc_order id="order-1" first="IP" then="Webserver" kind="Optional"/>
<rsc_order id="order-2" first="Database" then="Webserver" kind="Mandatory" />
</constraints>
Because the above example lets ``symmetrical`` default to TRUE, **Webserver**
must be stopped before **Database** can be stopped, and **Webserver** should be
stopped before **IP** if they both need to be stopped.

single: resource; location relative to other resources
.. _s-resource-colocation:
Placing Resources Relative to other Resources
#############################################
*Colocation constraints* tell the cluster that the location of one resource
depends on the location of another one.
Colocation has an important side-effect: it affects the order in which
resources are assigned to a node. Think about it: You can't place A relative to
B unless you know where B is [#]_.
So when you are creating colocation constraints, it is important to
consider whether you should colocate A with B, or B with A.
Another thing to keep in mind is that, assuming A is colocated with
B, the cluster will take into account A's preferences when
deciding which node to choose for B.
For a detailed look at exactly how this occurs, see
`Colocation Explained <http://clusterlabs.org/doc/Colocation_Explained.pdf>`_.
.. important::
Colocation constraints affect *only* the placement of resources; they do *not*
require that the resources be started in a particular order. If you want
resources to be started on the same node *and* in a specific order, you need
both an ordering constraint (see :ref:`s-resource-ordering`) *and* a colocation
constraint, or alternatively, a group (see :ref:`group-resources`).

+----------------+---------+--------------------------------------------------------+
Mandatory Placement
___________________
Mandatory placement occurs when the constraint's score is
**+INFINITY** or **-INFINITY**. In such cases, if the constraint can't be
satisfied, then the **rsc** resource is not permitted to run. For
``score=INFINITY``, this includes cases where the ``with-rsc`` resource is
not active.
If you need resource **A** to always run on the same machine as
resource **B**, you would add the following constraint:
.. topic:: Mandatory colocation constraint for two resources
.. code-block:: xml
<rsc_colocation id="colocate" rsc="A" with-rsc="B" score="INFINITY"/>
Remember, because **INFINITY** was used, if **B** can't run on any
of the cluster nodes (for whatever reason) then **A** will not
be allowed to run. Whether **A** is running or not has no effect on **B**.
Alternatively, you may want the opposite -- that **A** *cannot*
run on the same machine as **B**. In this case, use ``score="-INFINITY"``.
.. topic:: Mandatory anti-colocation constraint for two resources
.. code-block:: xml
<rsc_colocation id="anti-colocate" rsc="A" with-rsc="B" score="-INFINITY"/>
Again, by specifying **-INFINITY**, the constraint is binding. So if the
only place left to run is where **B** already is, then **A** may not run anywhere.
As with **INFINITY**, **B** can run even if **A** is stopped. However, in this
case **A** also can run if **B** is stopped, because it still meets the
constraint of **A** and **B** not running on the same node.
Advisory Placement
__________________
If mandatory placement is about "must" and "must not", then advisory
placement is the "I'd prefer if" alternative. For constraints with
scores greater than **-INFINITY** and less than **INFINITY**, the cluster
will try to accommodate your wishes but may ignore them if the
alternative is to stop some of the cluster resources.
As in life, where if enough people prefer something it effectively
becomes mandatory, advisory colocation constraints can combine with
other elements of the configuration to behave as if they were
mandatory.
.. topic:: Advisory colocation constraint for two resources
.. code-block:: xml
<rsc_colocation id="colocate-maybe" rsc="A" with-rsc="B" score="500"/>
.. _s-coloc-attribute:
Colocation by Node Attribute
____________________________
The ``node-attribute`` property of a colocation constraints allows you to express
the requirement, "these resources must be on similar nodes".
As an example, imagine that you have two Storage Area Networks (SANs) that are
not controlled by the cluster, and each node is connected to one or the other.
You may have two resources **r1** and **r2** such that **r2** needs to use the same
SAN as **r1**, but doesn't necessarily have to be on the same exact node.
In such a case, you could define a :ref:`node attribute <node_attributes>` named
**san**, with the value **san1** or **san2** on each node as appropriate. Then, you
could colocate **r2** with **r1** using ``node-attribute`` set to **san**.

resources, such as:

<rsc_order id="order-1" first="A" then="B" />
<rsc_order id="order-2" first="B" then="C" />

Ordered Set
___________
To simplify this situation, resource sets (see :ref:`s-resource-sets`) can be used
within ordering constraints:
.. topic:: A chain of ordered resources expressed as a set
.. code-block:: xml
<constraints>
<rsc_order id="order-1">
<resource_set id="ordered-set-example" sequential="true">
<resource_ref id="A"/>
<resource_ref id="B"/>
<resource_ref id="C"/>
<resource_ref id="D"/>
</resource_set>
</rsc_order>
</constraints>
While the set-based format is not less verbose, it is significantly easier to
get right and maintain.
.. important::
If you use a higher-level tool, pay attention to how it exposes this
functionality. Depending on the tool, creating a set **A B** may be equivalent to
**A then B**, or **B then A**.
Ordering Multiple Sets
______________________
The syntax can be expanded to allow sets of resources to be ordered relative to
each other, where the members of each individual set may be ordered or
unordered (controlled by the ``sequential`` property). In the example below, **A**
and **B** can both start in parallel, as can **C** and **D**, however **C** and
**D** can only start once *both* **A** *and* **B** are active.
.. topic:: Ordered sets of unordered resources
.. code-block:: xml
<constraints>
<rsc_order id="order-1">
<resource_set id="ordered-set-1" sequential="false">

.. topic:: Visual representation of the start order for two ordered sets of

- .. image:: ../../shared/en-US/images/two-sets.png
+ .. image:: images/two-sets.png
:alt: Two ordered sets
Of course either set -- or both sets -- of resources can also be internally
ordered (by setting ``sequential="true"``) and there is no limit to the number
of sets that can be specified.
.. topic:: Advanced use of set ordering - Three ordered sets, two of which are

:alt: Three ordered sets
.. important::
An ordered set with ``sequential=false`` makes sense only if there is another
set in the constraint. Otherwise, the constraint has no effect.
Resource Set OR Logic
_____________________
The unordered set logic discussed so far has all been "AND" logic. To illustrate
this take the 3 resource set figure in the previous section. Those sets can be
expressed, **(A and B) then (C) then (D) then (E and F)**.
Say for example we want to change the first set, **(A and B)**, to use "OR" logic
so the sets look like this: **(A or B) then (C) then (D) then (E and F)**. This
functionality can be achieved through the use of the ``require-all`` option.
This option defaults to TRUE which is why the "AND" logic is used by default.
Setting ``require-all=false`` means only one resource in the set needs to be
started before continuing on to the next set.
.. topic:: Resource Set "OR" logic: Three ordered sets, where the first set is
internally unordered with "OR" logic
.. code-block:: xml
<constraints>
<rsc_order id="order-1">
<resource_set id="ordered-set-1" sequential="false" require-all="false">
<resource_ref id="A"/>

</resource_set>
<resource_set id="ordered-set-2" sequential="true">

</resource_set>
<resource_set id="ordered-set-3" sequential="false">
<resource_ref id="E"/>
<resource_ref id="F"/>
</resource_set>
</rsc_order>
</constraints>
.. important::
An ordered set with ``require-all=false`` makes sense only in conjunction with
``sequential=false``. Think of it like this: ``sequential=false`` modifies the set
to be an unordered set using "AND" logic by default, and adding
``require-all=false`` flips the unordered set's "AND" logic to "OR" logic.
.. _s-resource-sets-colocation:
Colocating Sets of Resources
############################
Another common situation is for an administrator to create a set of
colocated resources.
The simplest way to do this is to define a resource group (see
:ref:`group-resources`), but that cannot always accurately express the desired
relationships. For example, maybe the resources do not need to be ordered.
Another way would be to define each relationship as an individual constraint,
but that causes a difficult-to-follow constraint explosion as the number of
resources and combinations grow.
.. topic:: Colocation chain as individual constraints, where A is placed first,
then B, then C, then D
.. code-block:: xml
<constraints>
<rsc_colocation id="coloc-1" rsc="D" with-rsc="C" score="INFINITY"/>
<rsc_colocation id="coloc-2" rsc="C" with-rsc="B" score="INFINITY"/>
<rsc_colocation id="coloc-3" rsc="B" with-rsc="A" score="INFINITY"/>
</constraints>
To express complicated relationships with a simplified syntax [#]_,
:ref:`resource sets <s-resource-sets>` can be used within colocation constraints.
.. topic:: Equivalent colocation chain expressed using **resource_set**
.. code-block:: xml
<constraints>
<rsc_colocation id="coloc-1" score="INFINITY" >
<resource_set id="colocated-set-example" sequential="true">
<resource_ref id="A"/>
<resource_ref id="B"/>
<resource_ref id="C"/>
<resource_ref id="D"/>
</resource_set>
</rsc_colocation>
</constraints>
.. note::
Within a ``resource_set``, the resources are listed in the order they are
*placed*, which is the reverse of the order in which they are *colocated*.
In the above example, resource **A** is placed before resource **B**, which is
the same as saying resource **B** is colocated with resource **A**.
As with individual constraints, a resource that can't be active prevents any
resource that must be colocated with it from being active. In both of the two
previous examples, if **B** is unable to run, then both **C** and by inference **D**
must remain stopped.
.. important::
If you use a higher-level tool, pay attention to how it exposes this
functionality. Depending on the tool, creating a set **A B** may be equivalent to
**A with B**, or **B with A**.
Resource sets can also be used to tell the cluster that entire *sets* of
resources must be colocated relative to each other, while the individual
members within any one set may or may not be colocated relative to each other
(determined by the set's ``sequential`` property).
In the following example, resources **B**, **C**, and **D** will each be colocated
with **A** (which will be placed first). **A** must be able to run in order for any
of the resources to run, but any of **B**, **C**, or **D** may be stopped without
affecting any of the others.

.. note::
Pay close attention to the order in which resources and sets are listed.
While the members of any one sequential set are placed first to last (i.e., the
colocation dependency is last with first), multiple sets are placed last to
first (i.e. the colocation dependency is first with last).
.. important::
A colocated set with ``sequential="false"`` makes sense only if there is
another set in the constraint. Otherwise, the constraint has no effect.
There is no inherent limit to the number and size of the sets used.
The only thing that matters is that in order for any member of one set
in the constraint to be active, all members of sets listed after it must also
be active (and naturally on the same node); and if a set has ``sequential="true"``,
then in order for one member of that set to be active, all members listed
before it must also be active.
If desired, you can restrict the dependency to instances of promotable clone
resources that are in a specific role, using the set's ``role`` property.

Unlike ordered sets, colocated sets do not use the ``require-all`` option.

in any order and choose the correct one depending on the situation,
the cluster is not quite so smart. Yet.

What Is Pacemaker?
####################
Pacemaker is a high-availability *cluster resource manager* -- software that
runs on a set of hosts (a *cluster* of *nodes*) in order to preserve integrity
and minimize downtime of desired services (*resources*). [#]_ It is maintained
by the `ClusterLabs <https://www.ClusterLabs.org/>`_ community.
Pacemaker's key features include:
* Detection of and recovery from node- and service-level failures
* Ability to ensure data integrity by fencing faulty nodes
* Support for one or more nodes per cluster
* Support for multiple resource interface standards (anything that can be
scripted can be clustered)
* Support (but no requirement) for shared storage
* Support for practically any redundancy configuration (active/passive, N+1,
etc.)
* Automatically replicated configuration that can be updated from any node
* Ability to specify cluster-wide relationships between services,
such as ordering, colocation and anti-colocation
* Support for advanced service types, such as *clones* (services that need to
be active on multiple nodes), *promotable clones* (clones that can run in
one of two roles), and containerized services
* Unified, scriptable cluster management tools
.. note:: Fencing
*Fencing*, also known as *STONITH* (an acronym for Shoot The Other Node In
The Head), is the ability to ensure that it is not possible for a node to be
running a service. This is accomplished via *fence devices* such as
intelligent power switches that cut power to the target, or intelligent
network switches that cut the target's access to the local network.
Pacemaker represents fence devices as a special class of resource.
A cluster cannot safely recover from certain failure conditions, such as an
unresponsive node, without fencing.
Cluster Architecture
____________________
At a high level, a cluster can be viewed as having these parts (which together
are often referred to as the *cluster stack*):
* **Resources:** These are the reason for the cluster's being -- the services
that need to be kept highly available.
* **Resource agents:** These are scripts or operating system components that
start, stop, and monitor resources, given a set of resource parameters.
These provide a uniform interface between Pacemaker and the managed
services.
* **Fence agents:** These are scripts that execute node fencing actions,
given a target and fence device parameters.
* **Cluster membership layer:** This component provides reliable messaging,
membership, and quorum information about the cluster. Currently, Pacemaker
supports `Corosync <http://www.corosync.org/>`_ as this layer.
* **Cluster resource manager:** Pacemaker provides the brain that processes
and reacts to events that occur in the cluster. These events may include
nodes joining or leaving the cluster; resource events caused by failures,
maintenance, or scheduled activities; and other administrative actions.
To achieve the desired availability, Pacemaker may start and stop resources
and fence nodes.
* **Cluster tools:** These provide an interface for users to interact with the
cluster. Various command-line and graphical (GUI) interfaces are available.
Most managed services are not, themselves, cluster-aware. However, many popular
open-source cluster filesystems make use of a common *Distributed Lock
Manager* (DLM), which makes direct use of Corosync for its messaging and
membership capabilities and Pacemaker for the ability to fence nodes.

Pacemaker Architecture
______________________
Pacemaker itself is composed of multiple daemons that work together:
* pacemakerd
* pacemaker-attrd
* pacemaker-based
* pacemaker-controld
* pacemaker-execd
* pacemaker-fenced
* pacemaker-schedulerd
-.. image:: ../../shared/en-US/images/pcmk-internals.png
+.. image:: ../shared/images/pcmk-internals.png
:alt: Pacemaker software components
:scale: 65 %
:align: center
The Pacemaker master process (pacemakerd) spawns all the other daemons, and
respawns them if they unexpectedly exit.
The *Cluster Information Base* (CIB) is an
`XML <https://en.wikipedia.org/wiki/XML>`_ representation of the cluster's
configuration and the state of all nodes and resources. The *CIB manager*
(pacemaker-based) keeps the CIB synchronized across the cluster, and handles
requests to modify it.
The *attribute manager* (pacemaker-attrd) maintains a database of attributes
for all nodes, keeps it synchronized across the cluster, and handles requests
to modify them. These attributes are usually recorded in the CIB.
Given a snapshot of the CIB as input, the *scheduler* (pacemaker-schedulerd)
determines what actions are necessary to achieve the desired state of the
cluster.
The *local executor* (pacemaker-execd) handles requests to execute
resource agents on the local cluster node, and returns the result.
The *fencer* (pacemaker-fenced) handles requests to fence nodes. Given a target
node, the fencer decides which cluster node(s) should execute which fencing
device(s), and calls the necessary fencing agents (either directly, or via
requests to the fencer peers on other nodes), and returns the result.
The *controller* (pacemaker-controld) is Pacemaker's coordinator, maintaining a
consistent view of the cluster membership and orchestrating all the other
components.
Pacemaker centralizes cluster decision-making by electing one of the controller
instances as the 'Designated Controller' ('DC'). Should the elected DC process
(or the node it is on) fail, a new one is quickly established. The DC responds
to cluster events by taking a current snapshot of the CIB, feeding it to the
scheduler, then asking the executors (either directly on the local node, or via
requests to controller peers on other nodes) and the fencer to execute any
necessary actions.
.. note:: **Old daemon names**
The Pacemaker daemons were renamed in version 2.0. You may still find
references to the old names, especially in documentation targeted to
version 1.1.
.. table::
+-------------------+---------------------+
| Old name | New name |
+===================+=====================+

Node Redundancy Designs
_______________________
Pacemaker supports practically any `node redundancy configuration
<https://en.wikipedia.org/wiki/High-availability_cluster#Node_configurations>`_
including *Active/Active*, *Active/Passive*, *N+1*, *N+M*, *N-to-1* and
*N-to-N*.
Active/passive clusters with two (or more) nodes using Pacemaker and
`DRBD <https://en.wikipedia.org/wiki/Distributed_Replicated_Block_Device>`_ are
a cost-effective high-availability solution for many situations. One of the
nodes provides the desired services, and if it fails, the other node takes
over.

+.. image:: ../shared/images/pcmk-active-passive.png
:alt: Active/Passive Redundancy
:align: center
:scale: 75 %
Pacemaker also supports multiple nodes in a shared-failover design, reducing
hardware costs by allowing several active/passive clusters to be combined and
share a common backup node.

+.. image:: ../shared/images/pcmk-shared-failover.png
:alt: Shared Failover
:align: center
:scale: 75 %
When shared storage is available, every node can potentially be used for
failover. Pacemaker can even run multiple copies of services to spread out the
workload. This is sometimes called N to N Redundancy.

.. rubric:: Footnotes
.. [#] *Cluster* is sometimes used in other contexts to refer to hosts grouped
together for other purposes, such as high-performance computing (HPC),
but Pacemaker is not intended for those purposes.
