lvmlockd [start | stop | monitor | meta-data | validate-all]
This agent manages the lvmlockd daemon. "lvmlockd" is like "clvmd". Both are used by LVM commands to coordinate access to shared storage, but with different design and implementations. "lvmlockd" can use two lock managers: dlm and sanlock. This agent only supports "dlm + lvmlockd". If dlm (or corosync) are already being used by other cluster software, you are advised to select dlm, then configure "controld" resource agent for dlm and this agent for "lvmlockd". Otherwise, consider sanlock for "lvmlockd" if dlm/corosync is not required.
Using lvmlockd requires the settings in LVM configuration file (/etc/lvm/lvm.conf): "locking_type = 1" and "use_lvmlockd = 1". This RA will change the settings respectively if needed.
For more information, refer to manpage lvmlockd.8.

Example CRM Shell
The following is an example configuration for a lvmlockd resource using the crm(8) shell:
primitive p_lvmlockd ocf:heartbeat:lvmlockd \ op monitor timeout="90s" interval="30s" depth="0"
The following is an example configuration for a lvmlockd resource using pcs(8)
pcs resource create p_lvmlockd ocf:heartbeat:lvmlockd \ op monitor timeout="90s" interval="30s" OCF_CHECK_LEVEL="0"
