[OpenIndiana-discuss] ZFS Pool configuration hanging around

[Michelle Knight]

Thanks Bernd,

Here are the results... Note that there is a backup pool already mounted and 
running.

I think that part of my problem is that I didn't know to write a new label to 
a disk before putting it in another pool. I thought it was overwrite any 
previous pool label.  I was obviously wrong ... as usual :-)


mich at jaguar:/root# zpool import
  pool: backup
    id: 15407100200514227053
 state: FAULTED
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
        devices and try again.
        The pool may be active on another system, but can be imported using
        the '-f' flag.
