Hi Peter,
The root pool disk labeling/partitioning is not so easy.
I don't know which OpenIndiana release this is but in a previous
Solaris release we had a bug that caused the error message below
and the workaround is exactly what you did, use the -f option.
We don't yet have an easy way to clear a disk label, but
sometimes I just create a new test pool on the problematic disk,
destroy the pool, and start over with a more coherent label.
This doesn't work for scenarios. Some people use the dd command
to wipe an existing label, but you must use it carefully.
Thanks,
Cindy

Hi,
I was following the instructions in ZFS Troubleshooting Guide on how to
replace a disk in the root pool on x86 system. I'm using OpenIndiana,
ZFS pool v.28 with mirrored system rpool. The replacement disk is brand new.
root:~# zpool status
pool: rpool
state: DEGRADED
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are
unaffected.
action: Determine if the device needs to be replaced, and clear the errors
using 'zpool clear' or replace the device with 'zpool replace'.

I'm not very familiar with Solaris partitions and slices so somewhere in
the format/partition commands I must to have made a mistake because when
I try to replace the disk I'm getting the following error:
root:~# zpool replace rpool c2t5000CCA369C55DB8d0s0 c2t5000CCA369C89636d0s0
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c2t5000CCA369C89636d0s0 overlaps with
/dev/dsk/c2t5000CCA369C89636d0s2
root:~#
I used -f and it worked but I was wondering is there a way to completely
"reset" the new disk? Remove all partitions and start from scratch.
Thank you
Peter
