* Tue Dec 19 2023 Ken Gaillot <kgaillot@redhat.com> Pacemaker-2.1.7
- 1388 commits with 358 files changed, 23771 insertions(+), 17219 deletions(-)
- Features added since Pacemaker-2.1.6
+ build: allow building with libxml2 2.12.0 and greater
+ CIB: deprecate "ordering" attribute of "resource_set"
+ CIB: new cluster option "node-pending-timeout" (defaulting to 0, meaning
no timeout, to preserve existing behavior) allows fencing of nodes that do
not join Pacemaker's controller group within this much time after joining
the cluster
+ controller: PCMK_node_start_state now works with Pacemaker Remote nodes
+ tools: crm_verify now supports --quiet option (currently same as default
behavior, but in the future, verbose behavior might become the default,
so script writers are recommended to explicitly add --quiet if they do not
want output)
+ tools: crm_node supports standard --output-as/--output-to arguments
+ tests: CTSlab.py was renamed to cts-lab
- Fixes since Pacemaker-2.1.6
+ logging: restore ability to enable XML trace logs by file and function
(regression introduced in 2.1.6)
+ scheduler: avoid double free with disabled recurring actions
(regression introduced in 2.1.5)
+ tools: consider dampening argument when setting values with attrd_updater
(regression introduced in 2.1.5)
+ tools: wait for reply from crm_node -R (regression introduced in 2.0.5)
+ agents: handle dampening parameter consistently and correctly
+ CIB: be more strict about ignoring colocation elements without an ID
+ controller: do not check whether watchdog fencing is enabled
if "stonith-watchdog-timeout" is not configured
+ controller: don't try to execute agent action at shutdown
+ controller: avoid race condition when updating node state during join
+ controller: correctly determine state of a fenced node without a name
+ controller: wait a second between fencer connection attempts
+ libpacemaker: avoid shuffling clone instances unnecessarily
+ libpacemaker: get bundle container's promotion score from correct node
+ libpacemaker: role-based colocations now work with bundles
+ libpacemaker: clone-node-max now works with cloned groups
+ scheduler: compare anti-colocation dependent negative preferences against
stickiness
+ scheduler: consider explicit colocations with group members
+ scheduler: avoid fencing a pending node without a name
+ scheduler: properly evaluate rules in action meta-attributes
+ scheduler: properly sort rule-based blocks when overwriting values
+ tools: crm_resource --wait will now wait if any actions are pending
(previously it would wait only if new actions were planned)
+ tools: crm_verify --output-as=xml now includes detailed messages
+ tools: avoid showing pending nodes as having "<3.15.1" feature set in
crm_mon
+ tools: fix display of clone descriptions
+ tools: crm_resource now reports an error rather than timing out when
trying to restart an unmanaged resource
+ tools: crm_resource now properly detects which promoted role name to use
in ban and move constraints
- Public API changes since Pacemaker-2.1.6 (all API/ABI backward-compatible)
+ libcib: cib_t now supports transactions via new cib_api_operations_t
methods, new cib_transaction value in enum cib_call_options, and new
cib_t transaction and user members
+ libcib: cib_t now supports setting the ACL user for methods via new
cib_api_operations_t set_user() method
+ libcib: deprecate cib_api_operations_t methods inputfd(), noop(), quit(),
set_op_callback(), and signon_raw()
+ libcib: deprecate cib_call_options values cib_mixed_update,
cib_scope_local, and cib_zero_copy
+ libcib: deprecate cib_t op_callback member
+ libcrmcluster: deprecate set_uuid()
+ libcrmcluster: send_cluster_message()'s data argument is const
+ libcrmcommon: add enum pcmk_rc_e values pcmk_rc_compression,
pcmk_rc_ns_resolution, and pcmk_rc_no_transaction
+ libcrmcommon,libpe_rules,libpe_status: many APIs have been moved from
libpe_rules and libpe_status to libcrmcommon, sometimes with new names
(deprecating the old ones), as described below

- Changesets: 849
- Diff: 327 files changed, 22089 insertions(+), 12633 deletions(-)
- Features added since Pacemaker-2.0.5
+ support for OCF Resource Agent API 1.1 standard
- allow Promoted and Unpromoted role names in CIB (in addition to Master
and Slave, which are deprecated), and use new role names in output,
logs, and constraints created by crm_resource --ban
- advertise 1.1 support to agents, and provide notify_promoted_* and
notify_unpromoted_* environment variables to agents with notify actions
- support "reloadable" parameter attribute and "reload-agent" action in
agents that advertise 1.1 support
- support 1.1 standard in ocf:pacemaker:Dummy, ocf:pacemaker:remote, and
ocf:pacemaker:Stateful resource agents
- add "promoted-only" (in addition to "master-only", which is deprecated)
in crm_mon XML output for bans
+ support for noncritical resources
- colocation constraints accept an "influence" attribute that determines
whether dependent influences main resource's location (the default of
"true" preserves the previous behavior, while "false" makes the
dependent stop if it reaches its migration-threshold in failures rather
than cause both resources to move to another node)
- resources accept a "critical" meta-attribute that serves as default for
all colocation constraints involving the resource as the dependent, as
well as groups involving the resource
+ detail log uses millisecond-resolution timestamps when Pacemaker is built
with libqb 2.0 or later
+ CIB: deprecate the remove-after-stop cluster property, can_fail action
meta-attribute, and support for Upstart-based resources
+ controller: the PCMK_panic_action environment variable may be set to
sync-crash or sync-reboot to attempt to synchronize local
disks before crashing or rebooting, which can be helpful to
record cached log messages but runs the risk of the sync
hanging and leaving the host running after a critical error
+ tools: CIB_file="-" can be used to get the CIB from standard input
+ tools: crmadmin, crm_resource, crm_simulate, and crm_verify support
standard --output-as/--output-to options (including XML output,
intended for parsing by scripts and higher-level tools)
+ tools: crm_attribute accepts -p/--promotion option to operate on
promotion score (replacing crm_master, which is deprecated)
+ tools: crm_resource accepts --promoted option (replacing --master, which
is deprecated)
+ tools: crm_resource accepts --digests advanced option
+ tools: crm_simulate accepts --show-attrs and --show-failcounts options
- Build process changes since Pacemaker-2.0.5
+ Pacemaker requires newer versions of certain dependencies, including
Python 3.2 or later (support for Python 2 has been dropped), glib 2.32.0
or later, libqb 0.17.0 or later, GnuTLS 2.12.0 or later (to enable
Pacemaker Remote support), rpm 4.11.0 (if building RPMs), and a C library
that provides setenv() and unsetenv()
+ configure: --enable-legacy-links (which is deprecated) defaults to "no",
meaning that symbolic links will not be created for the
Pacemaker 1 daemon names
+ configure: --enable-compat-2.0 prevents certain output changes (most
significantly role names) to maintain compatibility with older
tools, scripts, and resource agents that rely on previous output
+ configure: --with-resource-stickiness-default sets a resource-stickiness
default in newly created CIBs
+ configure: --with-concurrent-fencing-default specifies default for
concurrent-fencing cluster property
+ configure: --with-sbd-sync-default specifies default for syncing start-up with sbd
+ configure: --with-ocfrapath specifies resource agent directories to search
+ configure: --with-ocfrainstalldir specifies where to install ocf:pacemaker agents
+ configure: --with-gnutls="no" explicitly disables support for
Pacemaker Remote and the remote-tls-port cluster property
+ configure: --with-acl has been removed (support for ACLs is always built)
+ configure: deprecated --with-pkgname, --with-pkg-name, --with-brand,
--enable-ansi, and --enable-no-stack options have been removed
+ environment variables file (typically /etc/sysconfig/pacemaker or
/etc/default/pacemaker) will be installed when "make install" is run
+ documentation has dependency on python3-sphinx instead of publican, and is
generated beneath doc/sphinx
- Fixes since Pacemaker-2.0.5
+ controller: always refresh agent meta-data after start, in case agent was
updated (regression introduced in 1.1.18)
+ tools: avoid crash when running crm_mon in daemonized mode with CGI output
(regression introduced in 2.0.3)

+ tools: exit with status 0 (not 64) for --version argument to crm_simulate
(regression introduced in 2.0.4) and crm_resource and crmadmin
(regression introduced in 2.0.5)
+ pacemaker-attrd: avoid race condition where transient attributes for a
leaving node could be reinstated when the node rejoins,
potentially causing a node that was just rebooted to exit
the cluster immediately after rejoining
+ controller,scheduler: fix year 2038 issues affecting shutdowns,
remote node fencing, last-rc-change, and
ticket last-granted dates
+ controller: retry scheduler connection after failure, to avoid cluster

is given, as well as when rsc-pattern with a regular
match is given
+ scheduler: node attribute rule expressions with a value-source of "param"
work with a resource parameter that itself is determined by a
node attribute rule expression
+ scheduler: avoid remote connection shutdown hanging when connection
history for node hosting connection is not last in CIB status
+ scheduler: route monitor cancellations behind moving remote connections correctly
+ libcrmcommon: avoid potential integer overflow when adding seconds to times
+ tools: cibsecret syncs to remote nodes and guest nodes as well as
cluster nodes
+ tools: show other available cluster information in crm_mon even if
fence history is not available
+ tools: retry failed fencer and CIB connections in crm_mon
+ tools: crm_mon reports if Pacemaker is waiting for sbd at start-up
+ tools: respect rules when showing node attributes in crm_mon

- Changesets: 885
- Diff: 549 files changed, 89865 insertions(+), 95100 deletions(-)
- Deprecated features removed since Pacemaker-1.1.18
+ All of these have newer forms, and the cluster will automatically convert
most older syntax usage in saved configurations to newer syntax as needed
+ Drop support for heartbeat and corosync 1 (whether using CMAN or plugin)
+ Drop support for rolling upgrades from Pacemaker versions older than 1.1.11
+ Drop support for built-in SMTP and SNMP in crm_mon
+ Drop support for legacy option aliases including default-action-timeout,
default-resource-stickiness, resource-failure-stickiness,
default-resource-failure-stickiness, is-managed-default,
and all names using underbar instead of dash
+ Drop support for "requires" operation meta-attribute
+ Drop support for the pcmk_*_cmd, pcmk_arg_map, and pcmk_poweroff_action
fence resource parameters
+ Drop support for deprecated command-line options to crmadmin,
crm_attribute, crm_resource, crm_verify, crm_mon, and stonith_admin
+ Drop support for operation meta-attributes in instance_attributes
+ Drop support for PCMK_legacy and LRMD_MAX_CHILDREN environment variables
+ Drop support for undocumented resource isolation feature
+ Drop support for processing very old saved CIB files (including
pre-0.6.0 start failure entries, pre-0.6.5 operation history entries,
pre-0.7 transition keys, pre-1.1.4 migration history entries,
pre-1.0 XML configuration schemas, pre-1.1.6 ticket state entries, and
pre-1.1.7 failed recurring operation history entries)
- Features added since Pacemaker-1.1.18
+ The pacemaker daemons have been renamed to make logs more intuitive
and easier to search
+ The default location of the Pacemaker detail log is now
/var/log/pacemaker/pacemaker.log (instead of being directly in /var/log),
and Pacemaker will no longer use Corosync's logging preferences;
configure script options are available to change default log locations
+ The detail log's message format has been improved
+ The master XML tag is deprecated in favor of using a standard clone tag
with a new "promotable" meta-attribute set to true, and the "master-max"
and "master-node-max" master meta-attributes are deprecated in favor of
new "promoted-max" and "promoted-node-max" clone meta-attributes;
documentation now refers to these as promotable clones rather than
master/slave, stateful, or multistate clones, and refers to
promotion scores instead of master scores
+ Administration-related documentation has been moved from the
"Pacemaker Explained" document to a new "Pacemaker Administration" document
+ record-pending now defaults to TRUE (pending actions are shown in status)
+ All Python code in Pacemaker now supports both Python 2.7 and Python 3
+ The command-line tools now return consistent, well-defined exit codes;
crm_error has an --exit option to list these
+ Pacemaker's systemd unit files now remove systemd's spawned process limit
+ mount, path, and timer systemd unit types are now supported as resources
+ A negative stonith-watchdog-timeout now tells the cluster to automatically
calculate the value based on SBD_WATCHDOG_TIMEOUT (which was the behavior
of 0 before 1.1.15; 0 retains its post-1.1.15 behavior of disabling use of
the watchdog as a fencing device)
+ The undocumented restart-type and role_after_failure
resource meta-attributes are now deprecated
+ Regression testing code has been consolidated and overhauled
(the most obvious change is new command names)
+ build: create /etc/pacemaker directory when installing
+ build: improved portability to BSD-based platforms
+ tools: crm_resource --cleanup now cleans only failed operation history;
crm_resource --reprobe retains the previous behavior of cleaning all
operation history
+ tools: add stonith_admin --validate option to check device configuration
+ tools: crm_node is now in the pacemaker-cli package (instead of pacemaker)
+ alerts: add epoch and usec alert variables for improved SNMP alerts
+ controller: deprecate "crmd-*" cluster options in favor of new names
+ scheduler: deprecate stonith-action value "poweroff" (use "off" instead)
+ scheduler: deprecate require-all in rsc_order

- This is the first release of the Pacemaker Cluster Resource Manager formerly part of Heartbeat.
- For those looking for the GUI, mgmtd, CIM or TSA components, they are now found in
the new pacemaker-pygui project. Build dependencies prevent them from being
included in Heartbeat (since the built-in CRM is no longer supported) and,
being non-core components, are not included with Pacemaker.

# Pacemaker
## What is Pacemaker?
Pacemaker is an advanced, scalable high-availability cluster resource manager.
It supports "N-node" clusters with significant capabilities for
managing resources and dependencies.
It will run scripts at initialization, when machines go up or down,
when related resources fail and can be configured to periodically check
resource health.
## Who is Pacemaker?
Pacemaker is distributed by [ClusterLabs](https://www.clusterlabs.org/).
Pacemaker was initially created by main architect and lead developer
Andrew Beekhof <andrew@beekhof.net>, with the aid of
project catalyst and advocate Lars Marowsky-Brée <lmb@suse.de>.
Many, many developers have contributed significantly to the project since.
The git log is the definitive record of their greatly appreciated
contributions.
The wider community of Pacemaker users is another essential aspect of the
project's existence, especially the many users who participate in the mailing
lists, blog about HA clustering, and otherwise actively make the project more
useful.
## Where do I get Pacemaker?
Pacemaker source code is distributed via
[Github](https://github.com/ClusterLabs/pacemaker).
From there, you can clone or download the repository to get the latest
development code, or download one of the official
[releases](https://github.com/ClusterLabs/pacemaker/releases).
## How do I install Pacemaker?
See [INSTALL.md](https://github.com/ClusterLabs/pacemaker/blob/main/INSTALL.md).
## What higher-level interfaces to Pacemaker are available?
There are multiple user interfaces for Pacemaker, including command-line
tools, graphical user interfaces and web frontends. The crm shell
used to be included in the Pacemaker source tree, but is now
a separate project.
This is not an exhaustive list:

### Can I convert some other cluster configuration to Pacemaker?
[clufter](https://github.com/jnpkrn/clufter) is a general-purpose tool
for converting one cluster representation format to another. Among other
possibilities, it can convert from a cluster based on rgmanager with CMAN to
a one based on pacemaker with corosync. See its documentation for details.
## How can I help?

.. index:: upgrade
Upgrading a Pacemaker Cluster
-----------------------------
.. index:: version
Pacemaker Versioning
####################
Pacemaker has an overall release version, plus separate version numbers for
certain internal components.
.. index::
single: version; release
* **Pacemaker release version:** This version consists of three numbers
(*x.y.z*).
The major version number (the *x* in *x.y.z*) increases when at least some
rolling upgrades are not possible from the previous major version. For example,
a rolling upgrade from 1.0.8 to 1.1.15 should always be supported, but a
rolling upgrade from 1.0.8 to 2.0.0 may not be possible.
The minor version (the *y* in *x.y.z*) increases when there are significant
changes in cluster default behavior, tool behavior, and/or the API interface
(for software that utilizes Pacemaker libraries). The main benefit is to alert
you to pay closer attention to the release notes, to see if you might be
affected.
The release counter (the *z* in *x.y.z*) is increased with all public releases
of Pacemaker, which typically include both bug fixes and new features.
.. index::
single: feature set
single: version; feature set
* **CRM feature set:** This version number applies to the communication between
full cluster nodes, and is used to avoid problems in mixed-version clusters.
The major version number increases when nodes with different versions would not
work (rolling upgrades are not allowed). The minor version number increases
when mixed-version clusters are allowed only during rolling upgrades. The
minor-minor version number is ignored, but allows resource agents to detect
cluster support for various features. [#]_
Pacemaker ensures that the longest-running node is the cluster's DC. This
ensures new features are not enabled until all nodes are upgraded to support
them.
.. index::
single: version; Pacemaker Remote protocol
* **Pacemaker Remote protocol version:** This version applies to communication
between a Pacemaker Remote node and the cluster. It increases when an older
cluster node would have problems hosting the connection to a newer
Pacemaker Remote node. To avoid these problems, Pacemaker Remote nodes will
accept connections only from cluster nodes with the same or newer
Pacemaker Remote protocol version.
Unlike with CRM feature set differences between full cluster nodes,
mixed Pacemaker Remote protocol versions between Pacemaker Remote nodes and
full cluster nodes are fine, as long as the Pacemaker Remote nodes have the
older version. This can be useful, for example, to host a legacy application
in an older operating system version used as a Pacemaker Remote node.
.. index::
single: version; XML schema
* **XML schema version:** Pacemaker’s configuration syntax — what's allowed in
the Configuration Information Base (CIB) — has its own version. This allows
the configuration syntax to evolve over time while still allowing clusters
with older configurations to work without change.
.. index::
single: upgrade; methods
Upgrading Cluster Software
##########################
There are three approaches to upgrading a cluster, each with advantages and
disadvantages.

.. index::
single: upgrade; shutdown
Complete Cluster Shutdown
_________________________
In this scenario, one shuts down all cluster nodes and resources,
then upgrades all the nodes before restarting the cluster.
#. On each node:
a. Shutdown the cluster software (pacemaker and the messaging layer).
#. Upgrade the Pacemaker software. This may also include upgrading the
messaging layer and/or the underlying operating system.
#. Check the configuration with the ``crm_verify`` tool.
#. On each node:
a. Start the cluster software.
Currently, only Corosync version 2 and greater is supported as the cluster
layer, but if another stack is supported in the future, the stack does not
need to be the same one before the upgrade.
One variation of this approach is to build a new cluster on new hosts.
This allows the new version to be tested beforehand, and minimizes downtime by
having the new nodes ready to be placed in production as soon as the old nodes
are shut down.
.. index::
single: upgrade; rolling upgrade
Rolling (node by node)
______________________
In this scenario, each node is removed from the cluster, upgraded, and then
brought back online, until all nodes are running the newest version.
Special considerations when planning a rolling upgrade:
* If you plan to upgrade other cluster software -- such as the messaging layer --
at the same time, consult that software's documentation for its compatibility
with a rolling upgrade.
* If the major version number is changing in the Pacemaker version you are
upgrading to, a rolling upgrade may not be possible. Read the new version's
release notes (as well the information here) for what limitations may exist.
* If the CRM feature set is changing in the Pacemaker version you are upgrading
to, you should run a mixed-version cluster only during a small rolling
upgrade window. If one of the older nodes drops out of the cluster for any
reason, it will not be able to rejoin until it is upgraded.
* If the Pacemaker Remote protocol version is changing, all cluster nodes
should be upgraded before upgrading any Pacemaker Remote nodes.
-See the ClusterLabs wiki's
-`release calendar <https://wiki.clusterlabs.org/wiki/ReleaseCalendar>`_
-to figure out whether the CRM feature set and/or Pacemaker Remote protocol
-version changed between the the Pacemaker release versions in your rolling
-upgrade.
+See the
+`Pacemaker release calendar
+<https://projects.clusterlabs.org/w/projects/pacemaker/pacemaker_release_calendar/>`_
+on the ClusterLabs wiki to figure out whether the CRM feature set and/or
+Pacemaker Remote protocol version changed between the the Pacemaker release
+versions in your rolling upgrade.
To perform a rolling upgrade, on each node in turn:
#. Put the node into standby mode, and wait for any active resources
to be moved cleanly to another node. (This step is optional, but
allows you to deal with any resource issues before the upgrade.)
#. Shutdown the cluster software (pacemaker and the messaging layer) on the node.
#. Upgrade the Pacemaker software. This may also include upgrading the
messaging layer and/or the underlying operating system.
#. If this is the first node to be upgraded, check the configuration
with the ``crm_verify`` tool.
#. Start the messaging layer.
This must be the same messaging layer (currently only Corosync version 2 and
greater is supported) that the rest of the cluster is using.
.. note::
Even if a rolling upgrade from the current version of the cluster to the
newest version is not directly possible, it may be possible to perform a
rolling upgrade in multiple steps, by upgrading to an intermediate version
first.
.. table:: **Version Compatibility Table**
+-------------------------+---------------------------+
| Version being Installed | Oldest Compatible Version |
+=========================+===========================+
| Pacemaker 2.y.z | Pacemaker 1.1.11 [#]_ |
+-------------------------+---------------------------+
| Pacemaker 1.y.z | Pacemaker 1.0.0 |
+-------------------------+---------------------------+
| Pacemaker 0.7.z | Pacemaker 0.6.z |
+-------------------------+---------------------------+
.. index::
single: upgrade; detach and reattach
Detach and Reattach
___________________
The reattach method is a variant of a complete cluster shutdown, where the
resources are left active and get re-detected when the cluster is restarted.
This method may not be used if the cluster contains any Pacemaker Remote nodes.
#. Tell the cluster to stop managing services. This is required to allow the
services to remain active after the cluster shuts down.
.. code-block:: none
# crm_attribute --name maintenance-mode --update true
#. On each node, shutdown the cluster software (pacemaker and the messaging
layer), and upgrade the Pacemaker software. This may also include upgrading
the messaging layer. While the underlying operating system may be upgraded
at the same time, that will be more likely to cause outages in the detached
services (certainly, if a reboot is required).
#. Check the configuration with the ``crm_verify`` tool.
#. On each node, start the cluster software.
Currently, only Corosync version 2 and greater is supported as the cluster
layer, but if another stack is supported in the future, the stack does not
need to be the same one before the upgrade.
#. Verify that the cluster re-detected all resources correctly.
#. Allow the cluster to resume managing resources again:
.. code-block:: none
# crm_attribute --name maintenance-mode --delete
.. note::
While the goal of the detach-and-reattach method is to avoid disturbing
running services, resources may still move after the upgrade if any
resource's location is governed by a rule based on transient node
attributes. Transient node attributes are erased when the node leaves the
cluster. A common example is using the ``ocf:pacemaker:ping`` resource to
set a node attribute used to locate other resources.
.. index::
pair: upgrade; CIB
Upgrading the Configuration
###########################
The CIB schema version can change from one Pacemaker version to another.
After cluster software is upgraded, the cluster will continue to use the older
schema version that it was previously using. This can be useful, for example,
when administrators have written tools that modify the configuration, and are
based on the older syntax. [#]_
However, when using an older syntax, new features may be unavailable, and there
is a performance impact, since the cluster must do a non-persistent
configuration upgrade before each transition. So while using the old syntax is
possible, it is not advisable to continue using it indefinitely.
Even if you wish to continue using the old syntax, it is a good idea to
follow the upgrade procedure outlined below, except for the last step, to ensure
that the new software has no problems with your existing configuration (since it
will perform much the same task internally).
If you are brave, it is sufficient simply to run ``cibadmin --upgrade``.
A more cautious approach would proceed like this:
#. Create a shadow copy of the configuration. The later commands will
automatically operate on this copy, rather than the live configuration.
.. code-block:: none
# crm_shadow --create shadow
.. index::
single: configuration; verify
#. Verify the configuration is valid with the new software (which may be
stricter about syntax mistakes, or may have dropped support for deprecated
features):
.. code-block:: none
# crm_verify --live-check
#. Fix any errors or warnings.
#. Perform the upgrade:
.. code-block:: none
# cibadmin --upgrade
#. If this step fails, there are three main possibilities:
a. The configuration was not valid to start with (did you do steps 2 and
3?).
#. The transformation failed; `report a bug <https://bugs.clusterlabs.org/>`_.
#. The transformation was successful but produced an invalid result.
If the result of the transformation is invalid, you may see a number of
- errors from the validation library. If these are not helpful, visit the
- `Validation FAQ wiki page <https://wiki.clusterlabs.org/wiki/Validation_FAQ>`_
- and/or try the manual upgrade procedure described below.
+ errors from the validation library. If these are not helpful, try the manual
+ upgrade procedure described below.
#. Check the changes:
.. code-block:: none
# crm_shadow --diff
If at this point there is anything about the upgrade that you wish to
fine-tune (for example, to change some of the automatic IDs), now is the
time to do so:
.. code-block:: none
# crm_shadow --edit
This will open the configuration in your favorite editor (whichever is
specified by the standard ``$EDITOR`` environment variable).
#. Preview how the cluster will react:
.. code-block:: none
# crm_simulate --live-check --save-dotfile shadow.dot -S
# dot -Tsvg shadow.dot -o shadow.svg
You can then view shadow.svg with any compatible image viewer or web
browser. Verify that either no resource actions will occur or that you are
happy with any that are scheduled. If the output contains actions you do
not expect (possibly due to changes to the score calculations), you may need
to make further manual changes. See :ref:`crm_simulate` for further details
on how to interpret the output of ``crm_simulate`` and ``dot``.
#. Upload the changes:
.. code-block:: none
# crm_shadow --commit shadow --force
In the unlikely event this step fails, please report a bug.
.. note::
It is also possible to perform the configuration upgrade steps manually:
#. Locate the ``upgrade*.xsl`` conversion scripts provided with the source
code. These will often be installed in a location such as
``/usr/share/pacemaker``, or may be obtained from the
`source repository <https://github.com/ClusterLabs/pacemaker/tree/main/xml>`_.
#. Run the conversion scripts that apply to your older version, for example:
.. code-block:: none
# xsltproc /path/to/upgrade06.xsl config06.xml > config10.xml
#. Locate the ``pacemaker.rng`` script (from the same location as the xsl
files).
#. Check the XML validity:
.. code-block:: none
# xmllint --relaxng /path/to/pacemaker.rng config10.xml
The advantage of this method is that it can be performed without the cluster
running, and any validation errors are often more informative.
What Changed in 2.1
###################
The Pacemaker 2.1 release is fully backward-compatible in both the CIB XML and
the C API. Highlights:
* Pacemaker now supports the **OCF Resource Agent API version 1.1**.
Most notably, the ``Master`` and ``Slave`` role names have been renamed to
``Promoted`` and ``Unpromoted``.
* Pacemaker now supports colocations where the dependent resource does not
affect the primary resource's placement (via a new ``influence`` colocation
constraint option and ``critical`` resource meta-attribute). This is intended
for cases where a less-important resource must be colocated with an essential
resource, but it is preferred to leave the less-important resource stopped if
it fails, rather than move both resources.
* If Pacemaker is built with libqb 2.0 or later, the detail log will use
**millisecond-resolution timestamps**.
* In addition to crm_mon and stonith_admin, the crmadmin, crm_resource,
crm_simulate, and crm_verify commands now support the ``--output-as`` and
``--output-to`` options, including **XML output** (which scripts and
higher-level tools are strongly recommended to use instead of trying to parse
the text output, which may change from release to release).

+on the ClusterLabs wiki.
What Changed in 2.0
###################
The main goal of the 2.0 release was to remove support for deprecated syntax,
along with some small changes in default configuration behavior and tool
behavior. Highlights:
* Only Corosync version 2 and greater is now supported as the underlying
cluster layer. Support for Heartbeat and Corosync 1 (including CMAN) is
removed.
* The Pacemaker detail log file is now stored in
``/var/log/pacemaker/pacemaker.log`` by default.
* The record-pending cluster property now defaults to true, which
allows status tools such as crm_mon to show operations that are in
progress.
* Support for a number of deprecated build options, environment variables,
and configuration settings has been removed.
* The ``master`` tag has been deprecated in favor of using the ``clone`` tag
with the new ``promotable`` meta-attribute set to ``true``. "Master/slave"
clone resources are now referred to as "promotable" clone resources.
* The public API for Pacemaker libraries that software applications can use
has changed significantly.

What Changed in 1.0
###################
New
___
* Failure timeouts.
* New section for resource and operation defaults.
* Tool for making offline configuration changes.
* ``Rules``, ``instance_attributes``, ``meta_attributes`` and sets of
operations can be defined once and referenced in multiple places.
* The CIB now accepts XPath-based create/modify/delete operations. See
``cibadmin --help``.
* Multi-dimensional colocation and ordering constraints.
* The ability to connect to the CIB from non-cluster machines.
* Allow recurring actions to be triggered at known times.
Changed
_______
* Syntax
* All resource and cluster options now use dashes (-) instead of underscores
(_)
* ``master_slave`` was renamed to ``master``
* The ``attributes`` container tag was removed
* The operation field ``pre-req`` has been renamed ``requires``
* All operations must have an ``interval``, ``start``/``stop`` must have it
set to zero
* The ``stonith-enabled`` option now defaults to true.
* The cluster will refuse to start resources if ``stonith-enabled`` is true (or
unset) and no STONITH resources have been defined
* The attributes of colocation and ordering constraints were renamed for
clarity.
* ``resource-failure-stickiness`` has been replaced by ``migration-threshold``.
* The parameters for command-line tools have been made consistent
* Switched to 'RelaxNG' schema validation and 'libxml2' parser
* id fields are now XML IDs which have the following limitations:
* id's cannot contain colons (:)
* id's cannot begin with a number
* id's must be globally unique (not just unique for that tag)
* Some fields (such as those in constraints that refer to resources) are
IDREFs.
This means that they must reference existing resources or objects in
order for the configuration to be valid. Removing an object which is
referenced elsewhere will therefore fail.
* The CIB representation, from which a MD5 digest is calculated to verify
CIBs on the nodes, has changed.
This means that every CIB update will require a full refresh on any
upgraded nodes until the cluster is fully upgraded to 1.0. This will result
in significant performance degradation and it is therefore highly
inadvisable to run a mixed 1.0/0.6 cluster for any longer than absolutely
necessary.
* Ping node information no longer needs to be added to ``ha.cf``. Simply
include the lists of hosts in your ping resource(s).
Removed
_______
* Syntax
* It is no longer possible to set resource meta options as top-level
attributes. Use meta-attributes instead.
* Resource and operation defaults are no longer read from ``crm_config``.
.. rubric:: Footnotes
.. [#] Before CRM feature set 3.1.0 (Pacemaker 2.0.0), the minor-minor version
number was treated the same as the minor version.
.. [#] Currently, Corosync version 2 and greater is the only supported cluster
stack, but other stacks have been supported by past versions, and may be
supported by future versions.
.. [#] Any active resources will be moved off the node being upgraded, so there
will be at least a brief outage unless all resources can be migrated
"live".
.. [#] Rolling upgrades from Pacemaker 1.1.z to 2.y.z are possible only if the
cluster uses corosync version 2 or greater as its messaging layer, and
the Cluster Information Base (CIB) uses schema 1.0 or higher in its
``validate-with`` property.
.. [#] As of Pacemaker 2.0.0, only schema versions pacemaker-1.0 and higher
are supported (excluding pacemaker-1.1, which was a special case).

Frequently Asked Questions
--------------------------
:Q: Who is this document intended for?
:A: Anyone who wishes to read and/or edit the Pacemaker source code.
Casual contributors should feel free to read just this FAQ, and
consult other chapters as needed.
----
.. index::
single: download
single: source code
single: git
single: git; GitHub
:Q: Where is the source code for Pacemaker?
:A: The `source code for Pacemaker <https://github.com/ClusterLabs/pacemaker>`_ is
kept on `GitHub <https://github.com/>`_, as are all software projects under the
`ClusterLabs <https://github.com/ClusterLabs>`_ umbrella. Pacemaker uses
`Git <https://git-scm.com/>`_ for source code management. If you are a Git newbie,
the `gittutorial(7) man page <http://schacon.github.io/git/gittutorial.html>`_
is an excellent starting point. If you're familiar with using Git from the
command line, you can create a local copy of the Pacemaker source code with:
**git clone https://github.com/ClusterLabs/pacemaker.git**
----
.. index::
single: git; branch
:Q: What are the different Git branches and repositories used for?
:A: * The `main branch <https://github.com/ClusterLabs/pacemaker/tree/main>`_
is the primary branch used for development.
* The `2.1 branch <https://github.com/ClusterLabs/pacemaker/tree/2.1>`_ is
the current release branch. Normally, it does not receive any changes, but
during the release cycle for a new release, it will contain release
candidates. During the release cycle, certain bug fixes will go to the
2.1 branch first (and be pulled into main later).
* The `2.0 branch <https://github.com/ClusterLabs/pacemaker/tree/2.0>`_,
`1.1 branch <https://github.com/ClusterLabs/pacemaker/tree/1.1>`_,
and separate
`1.0 repository <https://github.com/ClusterLabs/pacemaker-1.0>`_
are frozen snapshots of earlier release series, no longer being developed.
* Messages will be posted to the
`developers@ClusterLabs.org <https://lists.ClusterLabs.org/mailman/listinfo/developers>`_
mailing list during the release cycle, with instructions about which
branches to use when submitting requests.
----
:Q: How do I build from the source code?
:A: See `INSTALL.md <https://github.com/ClusterLabs/pacemaker/blob/main/INSTALL.md>`_
in the main checkout directory.
----
:Q: What coding style should I follow?
:A: You'll be mostly fine if you simply follow the example of existing code.
When unsure, see the relevant chapter of this document for language-specific
recommendations. Pacemaker has grown and evolved organically over many years,
so you will see much code that doesn't conform to the current guidelines. We
discourage making changes solely to bring code into conformance, as any change
requires developer time for review and opens the possibility of adding bugs.
However, new code should follow the guidelines, and it is fine to bring lines
of older code into conformance when modifying that code for other reasons.
----
.. index::
single: git; commit message
:Q: How should I format my Git commit messages?
:A: An example is "Feature: scheduler: wobble the frizzle better".
* The first part is the type of change, used to automatically generate the
change log for the next release. Commit messages with the following will
be included in the change log:
* **Feature** for new features
* **Fix** for bug fixes (**Bug** or **High** also work)
* **API** for changes to the public API
Everything else will *not* automatically be in the change log, and so
don't really matter, but types commonly used include:
* **Log** for changes to log messages or handling
* **Doc** for changes to documentation or comments
* **Test** for changes in CTS and regression tests
* **Low**, **Med**, or **Mid** for bug fixes not significant enough for a
change log entry
* **Refactor** for refactoring-only code changes
* **Build** for build process changes
* The next part is the name of the component(s) being changed, for example,
**controller** or **libcrmcommon** (it's more free-form, so don't sweat
getting it exact).
* The rest briefly describes the change. The git project recommends the
entire summary line stay under 50 characters, but more is fine if needed
for clarity.
* Except for the most simple and obvious of changes, the summary should be
followed by a blank line and a longer explanation of *why* the change was
made.
* If the commit is associated with a task in the `ClusterLabs project
manager <https://projects.clusterlabs.org/>`_, you can say
"Fixes T\ *n*" in the commit message to automatically close task
T\ *n* when the pull request is merged.
----
:Q: How can I test my changes?
:A: The source repository has some unit tests for simple functions, though this
is a recent effort without much coverage yet. Pacemaker's Cluster Test
Suite (CTS) has regression tests for most major components; these will
automatically be run for any pull requests submitted through GitHub, and
are sufficient for most changes. Additionally, CTS has a lab component that
can be used to set up a test cluster and run a wide variety of complex
tests, for testing major changes. See cts/README.md in the source
repository for details.
