From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joseph Qi Date: Thu, 23 Jul 2015 10:37:32 +0800 Subject: [Ocfs2-devel] Do you know this issue? thanks In-Reply-To: <55AFBD47020000F90000F7DF@relay2.provo.novell.com> References: <55AFBD47020000F90000F7DF@relay2.provo.novell.com> Message-ID: <55B0536C.8020603@huawei.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com 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)?
