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 CTDB lock and Samba state 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_lockThe 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. This must be on shared storage, e.g.:
/shared-fs/samba/private (required, 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): startStarts 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 \ smb_private_dir= string \ op monitor timeout="20" interval="10" depth="0"
