Issue

• Service with lvm resource fails to stop or recover when the file system on it cannot be unmounted:

• Red Hat cluster does not failover when active node lost access to SAN storage
• lvm resource failed to shutdown, causing the service to fail:

rgmanager[3010]: [lvm] Logical volume VolGroup/LogVol failed to shutdown

• My node did not reboot itself when it could not shutdown the lvm resource, even though self_fence="on"
• I tried to move a cluster service from node 2 to 1 with command clusvcadm -r <service> -m <node>.
  The result was failed and the service went down on node 2. To get it back working, I had to disable it a couple of times on node 2 and then re-enable it on node 2.
