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. # ####################################################################### # Initialization: : ${OCF_FUNCTIONS_DIR=${OCF_ROOT}/lib/heartbeat} . ${OCF_FUNCTIONS_DIR}/ocf-shellfuncs ####################################################################### # Default parameter values: # Some distro's ctdb package stores the persistent db in /var/lib/ctdb, # others store in /var/ctdb.

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. For more information see http://linux-ha.org/wiki/CTDB_(resource_agent) CTDB Resource Agent The location of a shared lock file or helper binary, common across all nodes. See CTDB documentation for details. CTDB shared lock file Should CTDB manage starting/stopping the Samba service for you? This will be deprecated in future, in favor of configuring a separate Samba resource. Should CTDB manage Samba? Should CTDB manage starting/stopping the Winbind service for you? This will be deprecated in future, in favor of configuring a separate Winbind resource. Should CTDB manage Winbind? Name of smb init script. Only necessary if CTDB is managing Samba directly. Will usually be auto-detected. Name of smb init script Name of nmb init script. Only necessary if CTDB is managing Samba directly. Will usually be auto-detected. Name of nmb init script Name of winbind init script. Only necessary if CTDB is managing Winbind directly. Will usually be auto-detected. Name of winbind init script If there are very many shares it may not be feasible to check that all of them are available during each monitoring interval. In that case this check can be disabled. Skip share check during monitor? If the amount of free memory drops below this value the node will become unhealthy and ctdb and all managed services will be shutdown. Once this occurs, the administrator needs to find the reason for the OOM situation, rectify it and restart ctdb with "service ctdb start". With CTDB 4.4.0 and later this parameter is ignored. Minimum amount of free memory (MB) When set to yes, the CTDB node will start in DISABLED mode and not host any public ip addresses. Start CTDB disabled? The directory containing various CTDB configuration files. The "nodes" and "notify.sh" scripts are expected to be in this directory. CTDB config file directory Full path to the CTDB binary. CTDB binary path Full path to the CTDB cluster daemon binary. CTDB Daemon binary path Full path to the domain socket that ctdbd will create, used for local clients to attach and communicate with the ctdb daemon. With CTDB 4.9.0 and later the socket path is hardcoded at build time, so this parameter is ignored. CTDB socket location (ignored with CTDB 4.9+) The directory to put the local CTDB database files in. Persistent database files will be put in ctdb_dbdir/persistent. CTDB database directory Full path to log file. To log to syslog instead, use the value "syslog". CTDB log file location Full path to ctdb runtime directory, used for storage of socket lock state. CTDB runtime directory location Indicates that ctdb should wait up to TIMEOUT seconds for a response to most commands sent to the CTDB daemon. CTDB timeout in seconds What debug level to run at (0-10). Higher means more verbose. CTDB debug level Maximum number of open files (for ulimit -n) Max open files Path to default samba config file. Only necessary if CTDB is managing Samba. Path to smb.conf 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. Samba private dir (deprecated) Which backend to use for storing user and possibly group information. Only necessary if CTDB is managing Samba. Samba passdb backend Which backend to use for SID/uid/gid mapping. Only necessary if CTDB is managing Samba. Samba idmap backend Which fileid:algorithm to use with vfs_fileid. The correct value depends on which clustered filesystem is in use, e.g.: for OCFS2, this should be set to "fsid". Only necessary if CTDB is managing Samba.
