I'm running a personal server at home with a CentOS 7 OS and a 12TB zpool. It's been running for a couple of years and yesterday I noticed some problems so I went in to have a look.
At first it seemed like one of my drives had failed, with zpool import
giving the following results:
pool: media
id: 1363376331138686016
state: DEGRADED
status: One or more devices contains corrupted data.
action: The pool can be imported despite missing or damaged devices.
The
fault tolerance of the pool may be compromised if imported.
see: http://zfsonlinux.org/msg/ZFS-8000-4J
config:
media DEGRADED
raidz1-0 DEGRADED
ata-ST3000DM001-1ER166_W500G55Q ONLINE
ata-ST3000DM001-1CH166_Z1F278KB UNAVAIL
sdc ONLINE
sde ONLINE
sdf ONLINE
This looks ok, however I can't seem to import the pool directly.
Running zpool import media
gives me:
cannot import 'media': I/O error
Destroy and re-create the pool from
a backup source.
I've looked around to figure out the problem but everything I've found has given me nothing.
Some other things I've tried:
zpool import -fFX
: zpool could not be importedzpool import -fFV
: zpool imported with FAULTED statuszpool status
: no pools available
Is anyone able to point me in the right direction? I'm not sure what my next course of diagnosis should be.
