[OpenIndiana-discuss] Another zfs issue

[Roy Sigurd Karlsbakk]

Hi all

I have this pool that has been suffering from some bad backplanes etc. Currently it's showing up ok, but after a resilver, a spare is stuck.

          raidz2-5     ONLINE       0     0     4
            c4t1d0     ONLINE       0     0     0
            c4t2d0     ONLINE       1     0     0
            c4t3d0     ONLINE       0     0     0
            c4t4d0     ONLINE       0     0     0
            spare-4    ONLINE       0     0     0
              c4t5d0   ONLINE       0     0     0
              c4t44d0  ONLINE       0     0     0
            c4t6d0     ONLINE       0     0     0
            c4t7d0     ONLINE       0     0     0

So, the VDEV seems ok, the pool reports two data errors, which is sad, but not a showstopper, however, trying to detach the spare from that vdev doesn's seem to easy

roy at dmz-backup:~$ sudo zpool detach dbpool c4t44d0
cannot detach c4t44d0: no valid replicas

iostat -en shows some issues with drives in that pool, but none on the two in the spare mirror

    0   0   0   0 c4t1d0
    0  82 131 213 c4t2d0
    0   0   0   0 c4t3d0
    0   0   0   0 c4t4d0
    0   0   0   0 c4t5d0
    0   0   0   0 c4t6d0
    0   0   0   0 c4t7d0
    0   0   0   0 c4t44d0

Is there a good explaination why I can't detach this mirror from the VDEV?

Vennlige hilsener / Best regards
