Hi,

I have current two way mirror configuration for my rpool.

To achieve CMU level redundancy i wanted to remove the second disk of existing mirror rpool and add new hard disk(same size) from different CMU.

Is this can be done online, Any standard procedure to do so..

root~# zpool status rpool

  pool: rpool

state: ONLINE

  scan: resilvered 84.9G in 11m32s with 0 errors on Fri Sep  2 17:29:12 2016

config:

        NAME          STATE     READ WRITE CKSUM

        rpool         ONLINE       0     0     0

          mirror-0    ONLINE       0     0     0

            c1t1d0s0  ONLINE       0     0     0

            c1t0d0s0  ONLINE       0     0     0

errors: No known data errors

root# echo|format|grep -i hitachi

     120. c1t0d0 <HITACHI-H109060SESUN600G-A690 cyl 64986 alt 2 hd 27 sec 668> ============> CMU6
