Clearly you have a corrupt filesystem. Of all these times that the filesystem has gone read-only, how many times have you done FSCKs? Have you done two FSCKs in a row? It's rare, but I've seen a second FSCK find stuff that was missed on the first run. A smart report will at least tell you if the drive has been suffering errors recently. Do you have a SMART report for the drive? <div class="gmail_quote">On Tue, Jan 26, 2010 at 5:15 AM, Muhammed Sameer <<a href="mailto:samix_119@yahoo.com">samix_119@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;">Hey, * Our server is going readonly atleast 10 - 15 times a day with the below error <snip> Jan 26 12:57:36 mailbox kernel: EXT3-fs error (device sdb1): ext3_free_blocks_sb: bit already cleared for block 53771686 Jan 26 12:57:36 mailbox kernel: Aborting journal on device sdb1.
