I know this sounds crazy, but if you don't have the money, and I don't anymore, then I think it's what I must do to give myself some remaining backup facility.
A few years ago I installed FreeNAS 11 and had the money to replace hardware failure, but now I don't, and I believe I have two hard disks out of three with a failure.
I was only receiving HD error reports:
Device: /dev/ada1, 272 Offline uncorrectable sectors
Device: /dev/ada1, Self-Test Log error count increased from 2 to 3 The boot volume state is DEGRADED: One or more devices has experienced an error resulting in data corruption. Applications may be affected.
Device: /dev/ada2, 8 Currently unreadable (pending) sectors
Device: /dev/ada1, 272 Currently unreadable (pending) sectors <this number is slowly rising>
but recently I've had:
Checking status of zfs pools:

entire pool from backup.

If I understand my position correctly, I have two HD's with hardware errors in different places and the ZFS is degraded.
I can't afford to replce the HD's, not for a while anyway, so my plan to make the most of the remaining hardware life is to mirror the data across all HD's. The theory being that I'll maintain at least one copy of the data somewhere across the three...
... so how do I move from the ZFS Pool FreeNAS_1 to three separate mirrors please? If indeed it is still possible. FreeNAS_2 is an unused volume so is available for scratch use.
Thanks in advance.
