Guys, I’m using this HDD (ST8000NM000A-2KE101) as a parity drive in a snapraid configuration, most of the time it is in spin down mode. A couple of days ago scrutiny shown a failed status with ‘command timeout’. Do you think it could be a real problem or is it because of the recovery time from the spin down status?
Why don’t you look at the drive’s SMART data?
That is the SMART data.
Usually parity drives are spun up. Hard to read or write the parity data if it’s not. I would make sure that otherwise it performs properly, and be ready to order a replacement if it doesn’t.
Snapraid parity is offline, so that’s not strictly accurate.
You build the parity, and then until you do a sync/scrub/rebuild they don’t do shit, so there’s no reason to keep them spun up.
If the drive are slow spinning up, then this is probably not a fatal concern, but there’s zero details here.
