[zfs-discuss] add/replace : strange zfs pool behaviour
Hi everybody;
I''m experimenting something weird on one of my zpool. One of my hard
drive failed (c3t3d0). The hot spare (c4t3d0) did its job, I
(physically) replaced it, and rebooted.
I have acknowledged the failure with fmadm too.
I now have this zpool config :
$ zpool status storage
pool: storage
state: ONLINE
scrub: resilver completed with 0 errors on Wed Feb 13 16:45:30 2008
config:
NAME STATE READ WRITE CKSUM
storage ONLINE 0 0 0
raidz1 ONLINE 0 0 0
c3t2d0 ONLINE 0 0 0
c4t3d0 ONLINE 0 0 0
c7t2d0 ONLINE 0 0 0
c7t3d0 ONLINE 0 0 0
I seethe disk with the "format" command :
$ sudo format

But I can''t insert it into the pool
$ sudo zpool replace storage c4t3d0 c3t3d0
invalid vdev specification
use ''-f'' to override the following errors:
/dev/dsk/c7t3d0s0 is part of active ZFS pool storage. Please see
zpool(1M).
$ sudo zpool add storage c4t3d0 c3t3d0
invalid vdev specification
use ''-f'' to override the following errors:
/dev/dsk/c7t3d0s0 is part of active ZFS pool storage. Please see
zpool(1M).
Does anyone have a clue ?
thanks.
