[OpenIndiana-discuss] zpool vdev membership misreported

[Justin Warwick]

jrw at valinor:~$ pfexec zpool attach media c2d1 c3d1
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c3d1s0 is part of active ZFS pool rpool. Please see zpool(1M).

Yet I do not see c3d1 in zpool status.  Initially I had 4 disks total, all
Seagate SATA drives, two separate plain two-disk mirrors. I added a couple
more disks, but havn't yet added them to a pool. I noticed that the device
identifiers changed (which I did not expect). I broke the mirror on the
"media" pool (i can't remember whey I did that). Since that time I have
been getting that message which seems to mean somehow the disk is halfway
stuck in the mirror. Should I just issue the -f override? Am I asking for
trouble if i do?
