Subject: [Ocfs2-devel] [PATCH] ocfs2/dlm: clear refmap bit of recovery lock while doing local recovery cleanup
Date: Tue, 2 Feb 2016 09:18:26 +0800 [thread overview]
Message-ID: <56B003E2.5080104@huawei.com> (raw)
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.
