[zfs-discuss] Cant''t detach spare device from pool
Hi!
I had trouble with my raidz in the way, that some of the blockdevices where not
found by the OSOL Box the other day, so the spare device was hooked on
automatically.
After fixing the problem, the missing device came back online, but I am unable
to detach the spare device, even though all devices are online and functional.
mamu at iunis:~# zpool status tank
pool: tank
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scrub: resilver in progress for 1h5m, 1,76% done, 61h12m to go
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
c9t0d1 ONLINE 0 0 0
c9t0d3 ONLINE 0 0 0 15K resilvered

c9t0d2 ONLINE 0 0 0 37,5K resilvered
c16t0d0 ONLINE 0 0 0 14,1G resilvered
cache
c18t0d0 ONLINE 0 0 0
spares
c16t0d0 INUSE currently in use
errors: No known data errors
mamu at iunis:~# zpool detach tank c16t0d0
cannot detach c16t0d0: no valid replicas
How can I solve the Problem?
Martin

You need to let the resilver complete before you can detach the spare. This is a known problem, CR 6909724. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6909724 On 18 Aug 2010, at 14:02, Dr. Martin Mundschenk wrote:> Hi! > > I had trouble with my raidz in the way, that some of the blockdevices where not found by the OSOL Box the other day, so the spare device was hooked on automatically. > > After fixing the problem, the missing device came back online, but I am unable to detach the spare device, even though all devices are online and functional. > > mamu at iunis:~# zpool status tank > pool: tank > state: ONLINE > status: One or more devices is currently being resilvered.

[zfs-discuss] Cant''t detach spare device from pool
After about 62 hours and 90%, the resilvering process got stuck. Since 12 hours nothing happens anymore. Thus, I can not detach the spare device. Is there a way to get the resilvering process back running? Martin Am 18.08.2010 um 20:11 schrieb Mark Musante:> You need to let the resilver complete before you can detach the spare.
