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 On 04/12/12 11:35, Peter Wood wrote:
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'. see: http://www.sun.com/msg/ZFS-8000-9P scan: resilvered 17.6M in 0h0m with 0 errors on Wed Apr 11 17:45:16 2012 config: NAME STATE READ WRITE CKSUM rpool DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 c2t5000CCA369C55DB8d0s0 OFFLINE 0 126 0 c2t5000CCA369D5231Cd0s0 ONLINE 0 0 0 errors: No known data errors root:~# 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?
