NAME

ocf_heartbeat_CTDB - CTDB Resource Agent

SYNOPSIS

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"
