#
# OVERVIEW
#
# When run by itself, CTDB can handle IP failover and includes scripts
# to manage various services (Samba, Winbind, HTTP, etc.). When run as
# a resource in a Pacemaker cluster, this additional functionality
# should not be used; instead one should define separate resources for
# CTDB, Samba, Winbind, IP addresses, etc.
#
# As of 2010-11-17, there is no separate OCF Samba or Winbind RA, so
# it is still possible to configure CTDB so that it manages these
# resources itself. In future, once Samba and Winbind RAs are
# available, this ability will be deprecated and ultimately removed.
#
# This RA intentionally provides no ability to configure CTDB such that
# it manages IP failover, HTTP, NFS, etc.
#
#
# TODO:
# - ctdb_stop doesn't really support multiple independent CTDB instances,
# unless they're running from distinct ctdbd binaries (it uses pkill
# $OCF_RESKEY_ctdbd_binary if "ctdb stop" doesn't work, which it might
# not under heavy load - this will kill all ctdbd instances on the
# system). OTOH, running multiple CTDB instances per node is, well,
# AFAIK, completely crazy. Can't run more than one in a vanilla CTDB
# cluster, with the CTDB init script. So it might be nice to address
# this for complete semantic correctness of the RA, but shouldn't
# actually cause any trouble in real life.
# - As much as possible, get rid of auto config generation
# - Especially smb.conf
# - Verify timeouts are sane
# - Monitor differentiate between error and not running?
# - Do we need to verify globally unique setting?
# - Should set CTDB_NODES to ${HA_RSCTMP}/ctdb (generated based on
# current nodes)
# - Look at enabling set_ctdb_variables() if necessary.
# - Probably possible for sysconfig file to not be restored if
# CTDB dies unexpectedly.

<longdesc lang="en">
This resource agent manages CTDB, allowing one to use Clustered Samba in a
Linux-HA/Pacemaker cluster. You need a shared filesystem (e.g. OCFS2 or GFS2) on
which the CTDB lock will be stored. Create /etc/ctdb/nodes containing a list
of private IP addresses of each node in the cluster, then configure this RA
as a clone. This agent expects the samba and windbind resources
to be managed outside of CTDB's control as a separate set of resources controlled
by the cluster manager. The optional support for enabling CTDB management of these
daemons will be depreciated.

# This assumes you want to manage a filesystem on a shared (SCSI) bus,

#
# NOTE: If 2 or more nodes mount the same file system read-write, and
# that file system is not designed for that specific purpose
# (such as GFS or OCFS2), and is not a network file system like
# NFS or Samba, then the filesystem is going to become
# corrupted.
#
# As a result, you should use this together with the stonith
# option and redundant, independent communications paths.

# If you don't do this, don't blame us when you scramble your

<longdesc lang="en">
Resource script for Filesystem. It manages a Filesystem on a
shared storage medium.
The standard monitor operation of depth 0 (also known as probe)
checks if the filesystem is mounted. If you want deeper tests,
set OCF_CHECK_LEVEL to one of the following values:
10: read first 16 blocks of the device (raw read)
This doesn't exercise the filesystem at all, but the device on
which the filesystem lives. This is noop for non-block devices
such as NFS, SMBFS, or bind mounts.
20: test if a status file can be written and read
The status file must be writable by root. This is not always the
case with an NFS mount, as NFS exports usually have the
"root_squash" option set. In such a setup, you must either use
read-only monitoring (depth=10), export with "no_root_squash" on
your NFS server, or grant world write permissions on the
directory where the status file is to be placed.

The use of a clone setup for local filesystems is forbidden
by default. For special setups like glusterfs, cloning a mount
of a local device with a filesystem like ext4 or xfs independently
on several nodes is a valid use case.

This option allows specifying how to handle processes that are
currently accessing the mount directory.
"true" : Default value, kill processes accessing mount point
"safe" : Kill processes accessing mount point using methods that
avoid functions that could potentially block during process
detection
"false" : Do not kill any processes.
The 'safe' option uses shell logic to walk the /procs/ directory
for pids using the mount point while the default option uses the
fuser cli tool. fuser is known to perform operations that can potentially
block if unresponsive nfs mounts are in use on the system.

# Description: IPsrcaddr - Preferred source address modification
#
# Author: John Sutton <john@scl.co.uk>
# Support: linux-ha@lists.linux-ha.org
# License: GNU General Public License (GPL)
# Copyright: SCL Internet
#
# Based on the IPaddr script.
#
# This script manages the preferred source address associated with
# packets which originate on the localhost and are routed through the
# default route. By default, i.e. without the use of this script or
# similar, these packets will carry the IP of the primary i.e. the
# non-aliased interface. This can be a nuisance if you need to ensure
# that such packets carry the same IP irrespective of which host in
# a redundant cluster they actually originate from.
#
# It can add a preferred source address, or remove one.
#
# usage: IPsrcaddr {start|stop|status|monitor|validate-all|meta-data}
#
# The "start" arg adds a preferred source address.
#
# Surprisingly, the "stop" arg removes it. :-)
#
# NOTES:
#
# 1) There must be one and not more than 1 default route! Mainly because
# I can't see why you should have more than one. And if there is more
# than one, we would have to box clever to find out which one is to be
# modified, or we would have to pass its identity as an argument.
#
# 2) The script depends on Alexey Kuznetsov's ip utility from the
# iproute aka iproute2 package.
#
# 3) No checking is done to see if the passed in IP address can
# reasonably be associated with the interface on which the default
# route exists. So unless you want to deliberately spoof your source IP,
# check it! Normally, I would expect that your haresources looks
# something like:
#
# nodename ip1 ip2 ... ipN IPsrcaddr::ipX
#
# where ipX is one of the ip1 to ipN.
#
# OCF parameters are as below:
# OCF_RESKEY_ipaddress

If set, the volume group will be activated exclusively. This option works one of
two ways. If the volume group has the cluster attribute set, then the volume group
will be activated exclusively using clvmd across the cluster. If the cluster attribute
is not set, the volume group will be activated exclusively using a tag and the volume_list
filter. When the tag option is in use, the volume_list in lvm.con must be initialized. This
can be as simple as setting 'volume_list = []' depending on your setup.

# when managing volume groups in the cluster. For Example, if you have a

<!DOCTYPE resource-agent SYSTEM "ra-api-1.dtd">
<resource-agent name="Route" version="0.1">
<version>1.0</version>
<longdesc lang="en">
Enables and disables network routes.
Supports host and net routes, routes via a gateway address,
and routes using specific source addresses.
This resource agent is useful if a node's routing table
needs to be manipulated based on node role assignment.
Consider the following example use case:
- One cluster node serves as an IPsec tunnel endpoint.
- All other nodes use the IPsec tunnel to reach hosts
in a specific remote network.
Then, here is how you would implement this scheme making use
of the Route resource agent:
- Configure an ipsec LSB resource.
- Configure a cloned Route OCF resource.
- Create an order constraint to ensure
that ipsec is started before Route.
- Create a colocation constraint between the
ipsec and Route resources, to make sure no instance
of your cloned Route resource is started on the
tunnel endpoint itself.

Resource script for Xinetd. It starts/stops services managed
by xinetd by enabling or disabling them in the configuration file.
The xinetd daemon itself must be running: we are not going to start or
stop it ourselves.
All services should have a line saying either "disable=yes" or "disable=no".
The script just changes those settings before reloading xinetd.
Important: in case the services managed by the cluster are the
only ones enabled, you should specify the -stayalive option for
xinetd or it will exit on Heartbeat stop. Alternatively, you may
enable some internal service such as echo.

This is the resource agent for the Apache Web server.
This resource agent operates both version 1.x and version 2.x Apache
servers.
The start operation ends with a loop in which monitor is
repeatedly called to make sure that the server started and that
it is operational. Hence, if the monitor operation does not
succeed within the start operation timeout, the apache resource
will end with an error status.
The monitor operation by default loads the server status page
which depends on the mod_status module and the corresponding
configuration file (usually /etc/apache2/mod_status.conf).
Make sure that the server status page works and that the access
is allowed *only* from localhost (address 127.0.0.1).
See the statusurl and testregex attributes for more details.

#
# This agent only supports being configured as a multistate Master
# resource.
#
# Slave vs Master role:
#
# During the 'Slave' role, galera instances are in read-only mode and
# will not attempt to connect to the cluster. This role exists only as
# a means to determine which galera instance is the most up-to-date. The
# most up-to-date node will be used to bootstrap a galera cluster that
# has no current members.
#
# The galera instances will only begin to be promoted to the Master role
# once all the nodes in the 'wsrep_cluster_address' connection address
# have entered read-only mode. At that point the node containing the
# database that is most current will be promoted to Master. Once the first
# Master instance bootstraps the galera cluster, the other nodes will be
# promoted to Master as well.
#
# Example: Create a galera cluster using nodes rhel7-node1 rhel7-node2 rhel7-node3
#
# pcs resource create db galera enable_creation=true \
# wsrep_cluster_address="gcomm://rhel7-auto1,rhel7-auto2,rhel7-auto3" meta master-max=3 --master
#
# By setting the 'enable_creation' option, the database will be automatically
# generated at startup. The meta attribute 'master-max=3' means that all 3
# nodes listed in the wsrep_cluster_address list will be allowed to connect
# to the galera cluster and perform replication.
#
# NOTE: If you have more nodes in the pacemaker cluster then you wish
# to have in the galera cluster, make sure to use location contraints to prevent
# pacemaker from attempting to place a galera instance on a node that is
# not in the 'wsrep_cluster_address" list.

While managing replication, the default behavior is to use uname -n

manually by adding a node attribute \${INSTANCE_ATTR_NAME}_mysql_master_IP
giving the IP to use for replication. For example, if the mysql primitive
you are using is p_mysql, the attribute to set will be
p_mysql_mysql_master_IP.

This option allows you to specify a maximum transfer
rate in kilobytes per second. This option is
most effective when using rsync with large files
(several megabytes and up). Due to the nature of
rsync transfers, blocks of data are sent, then if
rsync determines the transfer was too fast, it will
wait before sending the next data block. The result
is an average transfer rate equaling the specified
limit. A value of zero specifies no limit.
