zfs discuss - Apr 2011 - Can''t detach dev from 3-way mirror

Hi guys, I''ve been struggling with this for days.. I have a pool
that''s full of 3-way mirrors backed by iscsi targets, I botched the
machine (iscsi target) that handles 1/3 of the mirrors and now I''m
trying to detach the devices which are UNAVAIL and nowehere to be
found in /dev anymore :)

? ? ? ? ? ?c3t52d0 ?ONLINE ? ? ? 0 ? ? 0 ? ? 0

etc.. etc..

now try and remove the unavail drive:

root at xarchive01:~# zpool detach archive c3t19d0
cannot detach c3t19d0: no such pool or dataset
root at xarchive01:~#

Doesn''t matter which UNAVAIL disk I try, (there are a few more) I
always get the same error

I''m running nv134 (Nexenta)
SunOS xarchive01 5.11 NexentaOS_134f i86pc i386 i86pc Solaris
# zpool get version archive
NAME     PROPERTY  VALUE    SOURCE
archive  version   26       default

Thanks! :)
