Breaking a ZFS mirror - Solaris 11
So you've mirrored your system disk wrongly! This is how you would break it and fix the problem before re-mirroring:
root@solaris11server:~$ zpool status
pool: rpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scan: resilvered 108G in 20m20s with 0 errors on Fri Dec 2 10:16:44 2016
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c0t5000CCA0166ED0ECd0s0 ONLINE 0 0 0
c0t5000CCA0166F8C50d0 ONLINE 0 0 0
errors: No known data errors
Added mirror as disk not slice. Turned disk into an EFI/GPT tabled disk. Using format and selecting the disk gives this messsage:
selecting c0t5000CCA0166F8C50d0 [disk formatted] /dev/dsk/c0t5000CCA0166F8C50d0s0 is part of active ZFS pool rpool. Please see zpool(1M). Reading the primary EFI GPT label failed. Using backup label. Use the 'backup' command to restore the primary label.Do we use the back command? Don't know. We must break the mirror first though - using zpool detach:
root@solaris11server:~# zpool detach rpool c0t5000CCA0166F8C50d0
root@solaris11server:~# zpool status
pool: rpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.
scan: resilvered 108G in 20m20s with 0 errors on Fri Dec 2 10:16:44 2016
config:

rpool ONLINE 0 0 0
c0t5000CCA0166ED0ECd0s0 ONLINE 0 0 0

Now look at the partition map on our good disk:
root@solaris11server:~# prtvtoc /dev/rdsk/c0t5000CCA0166ED0ECd0s0
* /dev/rdsk/c0t5000CCA0166ED0ECd0s0 (volume "solaris") partition map
*
* Dimensions:
* 512 bytes/sector
* 625 sectors/track
* 20 tracks/cylinder
* 12500 sectors/cylinder
* 46875 cylinders
* 46873 accessible cylinders
*
* Flags:
* 1: unmountable
* 10: read-only
*
* Unallocated space:
* First Sector Last
* Sector Count Sector
* 0 12500 12499

2 5 01 0 585912500 585912499
And compare it with our bad disk:
root@solaris11server:~# prtvtoc /dev/rdsk/c0t5000CCA0166F8C50d0s0
* /dev/rdsk/c0t5000CCA0166F8C50d0s0 partition map

So let us label our bad disk with the proper SMI label - not the EFI one:
root@solaris11server:~# format -e /dev/rdsk/c0t5000CCA0166F8C50d0
selecting /dev/rdsk/c0t5000CCA0166F8C50d0

Now, let's copy the partition table of our good disk over to our bad one:
root@solaris11server:~# prtvtoc /dev/rdsk/c0t5000CCA0166ED0ECd0s0 | fmthard -s - /dev/rdsk/c0t5000CCA0166F8C50d0s2
fmthard: New volume table of contents now in place.
root@solaris11server:~# prtvtoc /dev/rdsk/c0t5000CCA0166F8C50d0s0
* /dev/rdsk/c0t5000CCA0166F8C50d0s0 partition map
*
* Dimensions:
* 512 bytes/sector
* 625 sectors/track
* 20 tracks/cylinder
* 12500 sectors/cylinder
* 46875 cylinders
* 46873 accessible cylinders
*
* Flags:
* 1: unmountable
* 10: read-only
*
* Unallocated space:
* First Sector Last
* Sector Count Sector
* 0 12500 12499
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
0 2 00 12500 585900000 585912499
2 5 01 0 585912500 585912499
All is now good, so let's attach (mirror) our system disks:
root@solaris11server:~# zpool attach rpool c0t5000CCA0166ED0ECd0s0 c0t5000CCA0166F8C50d0s0
Make sure to wait until resilver is done before rebooting.
root@solaris11server:~# zpool status
pool: rpool
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function in a degraded state.
action: Wait for the resilver to complete.
Run 'zpool status -v' to see device specific details.
scan: resilver in progress since Wed Dec 14 10:13:36 2016
1.52G scanned out of 108G at 58.9M/s, 30m52s to go
1.52G resilvered, 1.41% done

After the resilvering has finished, our system is mirrored correctly! :)
