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:
Hi Cindy,
well, actually the two LUNs represent two different raid boxes that are
conencted through a FC switch to which the host is attached too.
I simply added these two FC LUNs to a pool, but from what you all are
telling me, I should be good, by adding two equal LUNs as described and
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,

Yes.
zpool attach pool existing_device new_device
Do that for each of the vdev devices you
Hi Darren,
gee, thanks. Of course the would be a resilver due for each vdev, but that
shouldn't harm, although the vdevs are quite big.
Thanks,

Hi--
Yes, you would use the zpool attach command to convert a
non-redundant configuration into a mirrored pool configuration.

Of course there will be a resilver, otherwise the mirror won't get the
existing data and it wouldn't be a mirror.

Duh. Yeah, its Monday morning.
I didn't have 6 devices to play with so I tried to fake it.
It should look like this:
# zpool status test
pool: test
state: ONLINE
scan: resilvered 85.5K in 0h0m with 0 errors on Mon Oct 4 08:54:06
2010
config:
NAME STATE READ WRITE
To answer your other questions,
I'm not sure I'm following your FC raid description:
Are you saying you created two LUNs from a FC RAID array
and added them to the pool?
If so, then yes, you can still attach more LUNs from the
array to create a mirrored pool.
A best practice is to mirror
