Hi Cindy,
very well - thanks.
I noticed that either the pool you're using and the zpool that is
described inb the docs already show a mirror-0 configuration, which
isn't the case for my zpool:
zpool status obelixData
pool: obelixData
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
obelixData ONLINE 0 0 0
c4t210000D023038FA8d0 ONLINE 0 0 0
c4t210000D02305FF42d0 ONLINE 0 0 0
errors: No known data errors
Actually, this zpool consists of two FC raids and I think I created it
simply by adding these two devs to the pool.
Does this disqualify my zpool for upgrading?
Thanks,
budy

Hi--
Yes, you would use the zpool attach command to convert a
non-redundant configuration into a mirrored pool configuration.
http://docs.sun.com/app/docs/doc/819-5461/gcfhe?l=en&a=view
See:
Example 4–6 Converting a Nonredundant ZFS Storage Pool to a Mirrored
ZFS Storage Pool
If you have more than one device in the pool, you would continue to
attach a new disk to each existing device, like this:
# zpool status test
pool: test
state: ONLINE
scan: resilvered 85.5K in 0h0m with 0 errors on Mon Oct 4 08:44:35 2010
config:
NAME STATE READ WRITE CKSUM
test ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
c3t1d0 ONLINE 0 0 0
c3t2d0 ONLINE 0 0 0
c3t3d0 ONLINE 0 0 0
# zpool attach test c3t1d0 c4t1d0
# zpool attach test c3t2d0 c4t2d0
# zpool attach test c3t3d0 c4t3d0
This would create a mirrored pool with 3 two-way mirrors.
I would suggest attaching one disk at a time, letting it
resilver and then run a scrub to ensure that each new disk is
functional.
Thanks,
Cindy

Hi,
once I created a zpool of single vdevs not using mirroring of any
kind. Now I wonder if it's possible to add vdevs and mirror the
currently existing ones.
Thanks,
budy
