I have a zpool named rtank. I accidently attached a single drive to the pool.
I am an idiot I know :D Now I want to replace this single drive with a raidz
group. Below is the pool setup and what I tried:
NAME STATE READ WRITE CKSUM
rtank ONLINE 0 0 0
- raidz1 ONLINE 0 0 0
-- c4t0d0 ONLINE 0 0 0
-- c4t1d0 ONLINE 0 0 0
-- c4t2d0 ONLINE 0 0 0
-- c4t3d0 ONLINE 0 0 0
-- c4t4d0 ONLINE 0 0 0
-- c4t5d0 ONLINE 0 0 0
-- c4t6d0 ONLINE 0 0 0
-- c4t7d0 ONLINE 0 0 0
- raidz1 ONLINE 0 0 0
-- c3t0d0 ONLINE 0 0 0
-- c3t1d0 ONLINE 0 0 0
-- c3t2d0 ONLINE 0 0 0
-- c3t3d0 ONLINE 0 0 0
-- c3t4d0 ONLINE 0 0 0
-- c3t5d0 ONLINE 0 0 0
- c5d0 ONLINE 0 0 0 <--- single drive in the
pool not in any raidz
$ pfexec zpool replace rtank c5d0 raidz c3t6d0 c3t7d0 c3t8d0 c3t9d0 c3t10d0
c3t11d0
too many arguments
$ zpool upgrade -v
This system is currently running ZFS pool version 18.
Is what I am trying to do possible? If so what am I doing wrong? Thanks.

Below is the pool setup and what I tried:I think that the best you will be able to do is the turn this single drive into a mirror. It seems that this sort of human error occurs pretty often and there is not yet a way to properly fix it.

Alas you need the fix for: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=4852783 Until that arrives mirror the disk or rebuild the pool. --chris -- This message posted from opensolaris.org

I know we hate them but an "Are you sure?" may have helped here, and
may be a quicker fix than waiting for 4852783
(just thinking out loud here). Could the zfs command have worked out
c5d0 was a single disk and attaching it to the pool would have been
dumb?
