what are you using for managing the multipathing to your SAN? /Balu <div>On 9/23/07, Swapana Ghosh <<a href="mailto:swapana_ghosh@yahoo.com">swapana_ghosh@yahoo.com </a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi In our office environment few servers mostly database servers and yesterday it happened for one application server(first time) the partion is getting "read only". I was checking the archives, found may be similar kind of issues in the 2007-July archives. But how it has been solved if someone describes me that will be really helpful. In our case, just at the problem started found the line in log file as follows: EXT3-fs error (device dm-12): edxt3_find_entry: reading directory #2015496 offset 2 Then one blank line Then the line is Aborting journal on device dm-12. ext3_abort called Ext3-fs error (device dm-12): ext3_journal_start_sb: Detected aborted journal Remounting filesysem read-only Then the continuous line as follows: EXT3-fs error (device dm-12) in start_transaction: Journal has aborted The above message is continuous until we remount the filesystem and partion becomes 'read-write'. We could not figure it out what is the root cause of the system. We are using individual EMC luns and are configured with LVM volume groups and then mounted on logical volumes.
