Dear List,
I'm running a Rhel 6.4 cluster and periodically i'm unable to mount some volumes. The volumes are iSCSI attached and clvm confirms them to be healthy and reachable.
The mount fails, actually just hangs.
The failing volumes have the"blocked,join" status. Any ideas on how to unblock these specific volumes without rebooting the whole cluster ?
