Hi all, I have a RAID-Z2 setup with 6x 500Gb SATA disks. I exported the
array to use under a different system but during or after the export one of
the disks failed:
kja at localhost:~$ pfexec zpool import
pool: chronicle
id: 11592382930413748377
state: DEGRADED
status: One or more devices are missing from the system.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.
see: http://www.sun.com/msg/ZFS-8000-2Q
config:
chronicle DEGRADED
raidz2 DEGRADED
c9t2d0 UNAVAIL cannot open
c9t1d0 ONLINE
c9t0d0 ONLINE
c9t4d0 ONLINE
c9t5d0 ONLINE
c9t3d0 ONLINE
I have no success trying to reimport the pool:
kja at localhost:~$ pfexec zpool import -f chronicle
cannot import ''chronicle'': one or more devices is currently
unavailable
The disk has since been replaced, so now:
kja at localhost:~$ pfexec zpool import
pool: chronicle
id: 11592382930413748377
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://www.sun.com/msg/ZFS-8000-4J
config:
chronicle DEGRADED
raidz2 DEGRADED
c9t2d0 FAULTED corrupted data
c9t1d0 ONLINE
c9t0d0 ONLINE
c9t4d0 ONLINE
c9t5d0 ONLINE
c9t3d0 ONLINE
but "pfexec zpool import -f chronicle" still fails with the same
message.
I''ve Google''d this several times for a fix but to no avail.
Any assistance
is appreciated.

When I powered the system on, it made frighteningly loud clicking sounds and would not be acknowledged by any system I was running, like it wasn''t even there. - Kyle -------------- next part -------------- An HTML attachment was scrubbed...

I''m running vanilla 2009.06 since its release. I''ll definitely give it a shot with the Live CD. Also I tried importing with only the five good disks physically attached and get the same message. - Kyle On Mon, Sep 21, 2009 at 3:50 AM, Chris Murray <chrismurray84 at googlemail.com>wrote:> That really sounds like a scenario that ZFS would be able to cope with. > > What operating system are you using now?
