I have never seen this bug. >From the bug expression, it is caused by inode in memory and disk mismatch. Previously we found jbd2_journal_restart is not called correctly in ocfs2 and will cause inconsistent. I am not sure if it has relations. So could you check if there is any error occurred before (like storage link down)?
