zfs discuss - Jul 2008 - HELP changing concat to a mirror

Hi

I have managed to get this:
HOSTNAME$ zpool status
  pool: zp01
 state: ONLINE
 scrub: resilver completed with 0 errors on Wed Jul  2 11:55:27 2008
config:

        NAME        STATE     READ WRITE CKSUM
        zp01        ONLINE       0     0     0
          c0t2d0    ONLINE       0     0     0
          c0t3d0    ONLINE       0     0     0

But I wanted to get these in a mirror - I am unable to remove c0t3d0 from the
pool. There is already data in the pool with filesystems mounted. So I do not
wish to destroy the pool.

Please help
Mark

Currently your only option is to copy data somewhere else, destroy pool
and create a new one. Disk removal is being worked on I believe, but it
gets kinda complex when you have a bunch of snapshots, clones etc..

Mark,

If you don''t want to backup the data, destroy the pool, and
recreate the pool as a mirrored configuration, then another
option it to attach two more disks to create 2 mirrors of 2
disks.

See the output below.
