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@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.
