An LVM-activate resource fails to start with error lvmlockd[XXXX]: XXXXXX prepare_lockspace_dlm vg1 mismatching cluster names sys new_clustername arg old_clustername in a Pacemaker cluster

Solution Verified - Updated

Environment

  • Red Hat Enterprise Linux 8 (with the Resilient Storage Add-on)

Issue

  • An ocf:heartbeat:LVM-activate resource fails to start after changing the cluster name, and /var/log/messages shows the following log sequence.

Resolution

Update the LVM metadata on each shared volume group to use the new dlm cluster name. You can find the procedure in the following solution: How do I rename my Red Hat Enterprise Linux High Availability cluster? | Handling dlm volume groups.

Root Cause

The cluster name was changed without updating the LVM metadata of shared volume groups that use lvmlockd and dlm. The LVM metadata must be updated on each volume group so that the volume group can be activated after the cluster name has been changed.
