Raid 10 & HDD failure
So... we have a Raid 10 setup using 4 HDD's. These HDD's are "named" 0,1,2 and 3.
HDD #3 is experiencing read/write failures and a check via a utility program confirms that that HDD needs to be replaced.
This was found because #2 had degraded (even though #3 still displayed as "ok"). Shortly after #2 degraded, #1 also degraded.
After adjusting some settings on the controller card (AMCC 9550sx), we now have 0 and 1 as OK, but #2 cannot pass beyond a 49% rebuild status. The status keeps pausing and resetting back to 44% where it rebuilds to 49% and then the cycle starts again. #3 shows as being "ok" as well, however we know that this drive is failing and cannot be read/written to correctly and must be replaced.
My questions are:
1) Why did #1 degrade?
2) Can #3 be yanked and replaced with 0 and 1 showing as "OK", and 2 still degraded? (does not 3 rebuild from 2 and vice versa?)
Thanks for any assistance!
