I've got an on board Nvidia raid controller with my boot drives in Raid 0 and my storage drives in Raid 1. I suddenly started having problems with at least one of my hard drives, I'm hoping someone might be able to help me shed some light on what is going on. I can't paste specific error messages at the moment but will be able to later.
So far the symptoms are thus:
Occasionally the OS (ubuntu 9.04) decides that the mirror is read only. When I tried to reboot I was getting I/O errors and it was listing a sector. What is strange is the I/O errors were listed for /dev/sda which is one of the striped drives. I threw smartmontools on there and checked the logs for the drives. The two drives in the Raid 0 have a few read errors but nothing obviously wrong, (that I saw). The mirrored drives both have an extremely high read error count, and if I recall correctly they were identical. What I'm wondering is if anyone has any idea if this means there's something wrong with the actual array, is there something wrong with the raid controller, or am I unfortunate enough to have two drives in a mirror die at once? The drives in the mirror are identical 1TB Samsung drives, purchased together, which is why I'm afraid I may be losing both. Any ideas/suggestions/help would be appreciated.
Also the raid controller lists both arrays as "Healthy".
Thanks in advance!
