So the day has come. I woke up to an email informing me that my FreeNAS volume is in a degraded state. This data is very important to me and family. I'm running an older version of FreeNAS as stated in the title so hopefully someone can still help me. When I view the volume status I see the volume status of "DEGRADED". Three of the 4 drives are "ONLINE" and one is "UNAVAIL". When I click the "UNAVAIL" drive the only option I see is a replace button. The email I received from the server is:
The volume Edmund (ZFS) state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.
I later received another email very similar with the added information:
The volume Edmund (ZFS) state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.
Device: /dev/ada2, unable to open device
I received one more email with a wall of text that I'll add as a reply to this thread.
I never received any SMART report saying the drive was failing. I don't know if FreeNAS even sees the drive anymore or if it is completely dead. Any way to tell?
This array was a z2 array consisting of 4 drives that were 4TB each. If my understanding is correct my data will be fine even if I lose 1 more drive.
I think I can follow the manual's instructions to replace the drive with a new drive, but my questions is this. Since I can still access the drive data and my "backup" of this data is currently not up to date (the backup might be a year or more old). Should I first back up the data first or should I just replace the drive and try to repair the volume? I know my backups should have been done more frequently but life happens and it was neglected (my fault). How would you suggest I proceed?
Thanks
