Ocfs2 users - Mar 2014 - OCFS2 imposed Read Only FileSystem on both Cluster nodes due to internal FileSystem Error

Hi,
     We observed that due to below error "ocfs2_commit_truncate: Inode
387098 has empty extent block at 387098".
The /dev/drbd0 filesystem on both Nodes we set to read only even though the
actual error was on disk of one Node.
So I wanted to know how to fence the Node when DISK I/O Error is seen in
OCFS2 filesstem.
Is this the recommended solution
echo 1 > /proc/fs/ocfs2_nodemanager/fence_method
