Hello,

FreeBSD RELENG_7, x86, a terrible disk array, called Promise RM-8000
with 8 disks on an ahc.
The pool is a RAIDZ2.
Tomorrow the array went crazy (its firmware is a total crap), so I had
to reboot both the machine and the disk array.

The effect:
pool: people
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: resilver completed with 0 errors on Thu Nov 22 10:45:27 2007
config:

NAME STATE READ WRITE CKSUM
people DEGRADED 0 0 0
raidz2 DEGRADED 0 0 0
da8 ONLINE 0 0 0
da3 FAULTED 0 0 0 corrupted data
da5 ONLINE 0 0 0
da6 ONLINE 0 0 0
da7 ONLINE 0 0 0
da9 ONLINE 0 0 0
da10 ONLINE 0 0 0
da4 FAULTED 0 0 0 corrupted data

errors: No known data errors

I've tried everything I could think of:
zpool replace people da3
invalid vdev specification
use '-f' to override the following errors:
da3 is in use (r1w1e1)

zpool replace -f people da3
invalid vdev specification
the following errors must be manually repaired:
da3 is in use (r1w1e1)

zpool offline people da3
cannot offline da3: no valid replicas

zpool online people da3
Bringing device da3 online
(nothing has changed, the device is still FAULTED)

Hmm. Is this this bug?
