I have two pools (both raidz2 - truenas core) one is 6 drives that are ~8 years old and chugging along fine. No critical data on them. (Hgst I think)
I have a 2nd pool that is 8 drives of Seagate x14 14th exos I got in 2021 - this is the one with a failed drive.
I was just alerted to one of the drives failing:
Device: /dev/ada4, ATA error count increased from 0 to 50.
Then
Device: /dev/ada4, 8 Offline uncorrectable sectors.
Then
Pool exotank state is DEGRADED: One or more devices are faulted in response to persistent errors. Sufficient replicas exist for the pool to continue functioning in a degraded state. The following devices are not healthy: * Disk ST14000NM001G
Questions:
-
I'm ordering a replacement drive will arrive within 2 days. Should I power down my server for now until new one arrives? Or leave it chugging along?
-
was considering adding more space anyway and replacing drives as I go along, so I might as well order a bigger drive now (26tb) and put it in. If I replace current dead drive with 26tb, and then in a few months replace the other 7 drives with 26tb.. it'll then increase my pool size to 8x26tb right?
Since I was planning on increasing my size and pulling these out seems like I might as well go ahead now and buy a 26tb.
Replacing 8x14 with 8x26 would give me a bump from 84 TB to 144tb (as I'm at 70% capacity at 84TB anyway).
