Oracle Clustered File System2 (OCFS2)
System hangs while mounting or unmounting OCFS partitions.
The problem occurs when OCFS partitions are unmounted on two nodes at
exactly the same time.
CAUTION: Do not reboot more than one system at the same time.
NOTE: It is not recommended to re-start the network on a live node. When trying to
re-start the network service from any live node in the cluster, the node hangs
indefinitely. This behavior is expected for OCFS2.
