Use smartctl from the smartmontools package. If mdadm says that
/dev/sdc (or cat /proc/mdstat) is at fault then use "smartctl -a
/dev/sdc" and it will print out all kinds of info on the drive
including its serial number which should be on a sticker on the case
of the drive. The programs included with smartmontools might have warned you of an impending failure. I have a smart self long test run om my drives 2 times a week. ...Bob On 06/16/2010 09:32 AM, Steven wrote: On Wed, June 16, 2010 13:13, Siju George wrote:Hope some one finds this helpful :-) --Siju Rebuilding RAID 1 Array in Linux with a new hard disk after a disk fault. =========================================================================Thanks, this might prove useful. However I do have a question... which might be just as important. How to identify which drive has failed in an array? I have 6 disks, 4 are used in raid (mdadm), the other 2 contain /boot, / and /home. /dev/sdc /dev/sdd /dev/sde /dev/sdf Each have 1 partition. /dev/md0 (raid 1) consists of /dev/sdc1 and /dev/sdd1 /dev/md1 (raid 1) consists of /dev/sde1 and /dev/sdf1 If a drive fails, how do I know which drive? This is a desktop system, not a server. |
