Hi,
As prior e-mail described, umount would hang after journal flushing failure.
When journal flushing in ocfs2_commit_cache() fails, following umount
procedure at stage of shutting journal may be blocked due to non-zero
transactions number.
Once jbd2_journal_flush() fails, the journal will be m

That causes new master node waiting forever.
