Hello all,
sorry for posting again some zpool replace problems, but it seems each issue is different.
I'm running 8.0.2 release.
One of my disks was faulty. I found out on the forums different procedures, and did it through CLI:
- Offline the failed disk
- Powered off the system, physically changed the disk with a brand new one
- Powered on the system and did zpool replace, with success (some errors though).
Here is the status after the zpool replace:
[maison@freenas] ~# zpool status -v RAID
pool: RAID
state: DEGRADED
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

To clear the errors, I did a zpool scrub, it seems it helped!
Status after the scrub:
[maison@freenas] /# zpool status -v
pool: RAID
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

It seems not so bad, now. My data is available, no know errors.
But I'm not sure what is the next step to move the pool back to Online.
Any recommendation?
Thanks,
Jeremie
