Posted by 24x7group, 05-02-2011, 11:18 AM I suggest getting that disk replaced asap, it shouldn't happen this much.
Posted by just-centos, 05-02-2011, 11:28 AM i tell my DC to replace HDD but they said "we checked completely all of your server hardwares and there isn't any hardware issue" they believe that is a sofware problem because after reboot any problems solved and repeat again.
Posted by shell-box, 05-02-2011, 11:49 AM You might want to check the smart data on the drive with the issue. smartctl --all /dev/sdb if smart is installed. Have you tried fscking the drive? I had a similar problem a long time ago, fscking it would fix it for a while.. I believe eventually the drive had to be replaced.
Posted by tanfwc, 05-02-2011, 12:56 PM I had a experience where the raid controller card is going to die which cause this problem. I had it replace and everything is back to normal. You might want to ask how your DC confirm that it is not a hardware problem?
Posted by trustedadmins, 05-03-2011, 05:04 AM You need to check the 'dmesg' and '/var/log/messages' at te time the drive has become read-only. You will probabily be getting some 'libata' error message similar to the following. ================= ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen ata3.00: cmd ea/00:00:00:00:00/00:00:00:00:00/a0 tag 0 res 40/00:00:01:4f:c2/00:00:00:00:00/00 Emask 0x4 (timeout) ata3.00: status: { DRDY } ================= You can debug it further with the specific codes in the error message, referring to kernel.org.
