OCF_HEARTBEAT_LVMLOC(7)

NAME
ocf_heartbeat_lvmlockd - This agent manages the lvmlockd daemon

SYNOPSIS

lvmlockd [start | stop | monitor | meta-data | validate-all]

DESCRIPTION

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.
