Nothing will immediately happen unless you have another failure. The cluster lock disk is ONLY used when it is required to break a tie. i.e. you have some other failure which results in cluster reformation with exactly 50% of the cluster wanting to form a new cluster.

The cluster can start up and shutdown without error with a failed cluster lock and nodes can join and leave the cluster too. It is only used when there is another failure.

The cluster lock disk is checked hourly and if it has failed an error message will be reported in syslog to this effect. You will also see messages in syslog when the cluster starts if the lock disk is unavailable.

To recover, replace the lock disk and issue a vgcfgrestore as described in the manual:
