NAME
ocf_heartbeat_CTDB - CTDB Resource AgentSYNOPSIS
- CTDB [start | stop | monitor | meta-data | validate-all]
DESCRIPTION
- 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) on which the CTDB lock will be stored. Configure shares in smb.conf on all nodes, and create /etc/ctdb/nodes containing a list of private IP addresses of each node in the cluster. Configure this RA as a clone, and it will take care of the rest. For more information see http://linux-ha.org/wiki/CTDB_(resource_agent)
SUPPORTED PARAMETERS
ctdb_recovery_lock
- The location of a shared lock file, common across all nodes. This must be on shared storage, e.g.: /shared-fs/samba/ctdb.lock (required, string, no default)
smb_private_dir
- The directory for smbd to use for storing such files as smbpasswd and secrets.tdb. Old versions of CTBD (prior to 1.0.50) required this to be on shared storage. This parameter should not be set for current versions of CTDB, and only remains in the RA for backwards compatibility. (optional, string, no default)
ctdb_config_dir
- The directory containing various CTDB configuration files. The "nodes" and "notify.sh" scripts are expected to be in this directory, as is the "events.d" subdirectory. (optional, string, default /etc/ctdb)
ctdb_binary
- Full path to the CTDB binary. (optional, string, default /usr/bin/ctdb)
ctdbd_binary
- Full path to the CTDB cluster daemon binary. (optional, string, default /usr/sbin/ctdbd)
ctdb_socket
- Full path to the domain socket that ctdbd will create, used for local clients to attach and communicate with the ctdb daemon. (optional, string, default /var/lib/ctdb/ctdb.socket)
ctdb_dbdir
- The directory to put the local CTDB database files in. Persistent database files will be put in ctdb_dbdir/persistent. (optional, string, default /var/lib/ctdb)
ctdb_logfile
- Full path to log file. To log to syslog instead, use the value "syslog". (optional, string, default /var/log/ctdb/log.ctdb)
ctdb_debuglevel
- What debug level to run at (0-10). Higher means more verbose. (optional, integer, default 2)
smb_conf
- Path to default samba config file. (optional, string, default /etc/samba/smb.conf)
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
- Starts the resource. Suggested minimum timeout: 90.
stop
- Stops the resource. Suggested minimum timeout: 100.
monitor
- Performs a detailed status check. Suggested minimum timeout: 20. Suggested interval: 10.
meta-data
- Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.
validate-all
- Performs a validation of the resource configuration. Suggested minimum timeout: 30.
EXAMPLE
The following is an example configuration for a CTDB resource using the crm(8) shell:
-
primitive example_CTDB ocf:heartbeat:CTDB \ params \ ctdb_recovery_lock=string \ op monitor timeout="20" interval="10" depth="0"
