I've been playing around with zfs for a bit, and ran into a problem
where i corrupted an entire drive (on purpose) by way of dd
if=/dev/urandom of=/dev/ad12 .. as expected, the zpool noticed:
su-2.05b# zpool status
pool: array1
state: ONLINE
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 Mon Jul 23 23:05:53 2007
config:
NAME STATE READ WRITE CKSUM
array1 ONLINE 0 0 0
raidz1 ONLINE 0 0 0
ad10 ONLINE 0 0 0
ad12 UNAVAIL 0 0 0 corrupted data

ad18 ONLINE 0 0 0
ad20 ONLINE 0 0 0
ad22 ONLINE 0 0 0
ad24 ONLINE 0 0 0
errors: No known data errors
now i want to resilver that disk, but the problem is this:
su-2.05b# zpool replace -f array1 ad12
invalid vdev specification
the following errors must be manually repaired:
ad12 is in use (r1w1e1)
but nothing is using that disk as far as i can tell! has anyone
successfully done this?
would it be better to use slices instead of whole disks for zfs on
freebsd? i want to get some experience with this so that i know
what not to do when a disk breaks for real :)
