[Ocfs2-devel] [PATCH] ocfs2/dlm: clear refmap bit of recovery lock while doing local recovery cleanup

[xuejiufei]

When recovery master down, dlm_do_local_recovery_cleanup() only
remove the $RECOVERY lock owned by dead node, but do not clear
the refmap bit. Which will make umount thread falling in dead loop
migrating $RECOVERY to the dead node.
