Hi Woke up this morning to find that my server is making some noises which are no normally associated with healthy disks. Looking on the system everything still looks fine in mdadm but there are some errors against sdg in dmesg indicating a media error and this combined with the noises its making makes me think its on the way out. The server is running 10.3 (32bit) and the disks are all 500gb SATA drives. Also the raid array does not hold the base OS filesystems just data filesystems.
Now sdg is part of a 6 disk RAID5 array (md0) using Linux software raid. I am assuming that the process to replace the disk is something like this: 1). Make sure I have an up to date backup of everything important off the server 2). Fail the disk in the Raid array by using a mdadm command? (as its not showing in there as having issues yet so I'll need to force it) 3). Remove disk from array using mdadm command? 4). Establish which physical disk is sdg (I have it down to 2 already i think) 5). Shutdown server 6). Replace disk with another of the same size (fortunately i have a spare). 7). start up server 8). Add disk to array (as new spare?) 9). re-sync the array onto the new disk I am not to sure about steps 2 and 3 and steps 8 and 9 so if anyone has any information, (or any good links to information on how to do this), I would be grateful if you could share you insights.
