@nrbbrtx:
LVM2 has deprecated clvm in favor of lvmlockd (lvm2-lockd in Focal) only
for VG access coordination AND it can use either DLM (dlm-controld) or
sanlock (sanlock) as lock managers.
http://manpages.ubuntu.com/manpages/focal/man8/lvmlockd.8.html
>From an upstream discussion thread, the lvmlockd benefits over clvm are:
"""
- lvmlockd supports two cluster locking plugins: dlm and sanlock. sanlock
plugin can supports up to ~2000 nodes that benefits LVM usage in big
virtualization / storage cluster, while dlm plugin fits HA cluster.
- lvmlockd has better design than clvmd. clvmd is command-line level based
locking system, which means the whole LVM software will get hang if any LVM
command gets dead-locking issue. However, lvmlockd is *resources* based cluster
locking. The resources to protect is VG and LV so that the deadlock issue will
be isolated inside the resource and
operations on other VG/LV can still proceed.
- lvmlockd can work with lvmetad.
"""
Now, instead of using the clvm pacemaker resource agent, you should use:
lvmlockdagent manages the lvmlockd daemon.
from the available resource agents list:
