Hi Wolf,
Which Solaris release is this?
If it is an OpenSolaris system running a recent build, you might
consider the zpool split feature, which splits a mirrored pool into two
separate pools, while the original pool is online.
If possible, attach the spare disks to create the mirrored pool as
a first step.
See the example below.
Thanks,
Cindy
You can attach the spare disks to the existing pool to create the
mirrored pool:
# zpool attach tank disk-1 spare-disk-1
# zpool attach tank disk-2 spare-disk-2
Which gives you a pool like this:
# zpool status tank
pool: tank
state: ONLINE
scrub: resilver completed after 0h0m with 0 errors on Tue Apr 27
14:36:28 2010
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c2t9d0 ONLINE 0 0 0
c2t5d0 ONLINE 0 0 0
mirror-1 ONLINE 0 0 0
c2t10d0 ONLINE 0 0 0
c2t6d0 ONLINE 0 0 0 56.5K resilvered
errors: No known data errors
Then, split the mirrored pool, like this:
# zpool split tank tank2
# zpool import tank2
# zpool status tank tank2
pool: tank
state: ONLINE
scrub: resilver completed after 0h0m with 0 errors on Tue Apr 27
14:36:28 2010
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
c2t9d0 ONLINE 0 0 0
c2t10d0 ONLINE 0 0 0
errors: No known data errors
pool: tank2
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
tank2 ONLINE 0 0 0
c2t5d0 ONLINE 0 0 0
c2t6d0 ONLINE 0 0 0

We would like to delete and recreate our existing zfs pool without losing any
data. The way we though we could do this was attach a few HDDs and create a new
temporary pool, migrate our existing zfs volume to the new pool, delete and
recreate the old pool and migrate the zfs volumes back. The big problem we have
is we need to do all this live, without any downtime. We have 2 volumes taking
up around 11TB and they are shared out to a couple windows servers with
comstar. Anyone have any good ideas?
