Subject: [Ocfs2-devel] ocfs2: Question for ocfs2_recovery_thread
Date: Sat, 18 May 2013 14:27:56 +0800 [thread overview]
Message-ID: <51971F6C.1000002@huawei.com> (raw)
Hi,
Once there is node down in the cluster, ocfs2_recovery_thread will be
triggered on each node. These threads then do the down node recovery by
get super lock.
I have several questions on this:
1) Why each node has to run such a thread? We know at last one node can
get the super lock and do the actual recovery.
2) If this thread is running but something error occurred, take
ocfs2_super_lock failed for example, the thread will exit without
clearing recovery map, will it cause other threads still waiting for
recovery in ocfs2_wait_for_recovery?
