After rebuilding a server which included moving the disks around and
replacing one, zpool status reports the following...
# zpool status
pool: export
state: DEGRADED
status: One or more devices could not be used because the label is
missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.
see: http://www.sun.com/msg/ZFS-8000-4J
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
export DEGRADED 0 0 0
mirror DEGRADED 0 0 0
c3d0 FAULTED 0 0 0 corrupted data
c6t1d0 ONLINE 0 0 0
c3d0 ONLINE 0 0 0
errors: No known data errors
#
Note there are two disks called c3d0. This is because all 3 disks have
physically moved into one of the others' slots, but one was swapped for
a new disk, so we've lost the original c3d0, but one of the other disks
in the zpool is in that position.
Now, what I want to do is detach the missing disk from the pool. I've
been in this situation twice now, and I've crossed my fingers and typed
zpool detach export c3d0
and on both occasions, it has detached the FAULTED disk rather than the
ONLINE disk, which is exactly what I wanted. However, was I just lucky
each time, or is there logic to pick the FAULTED disk when the disk name
isn't unique?
