zfs discuss - Sep 2006 - moving fs from a dead box

Folks,

Let''s say you have a box that dies with zfs filesystems from a san on  
them (a mirror config) and so you can''t export the fs.  Can you move  
the fs to a new box?  How so?

If you configure your SAN so new host can see disks just type ''zpool
import'' and you should see that pool from dead host then just type
''zpool import pool_namd''. If your dead host wasn''t
shutdown properly
you will have to force import with ''zpool import -f pool_name".

However make sure you are not importing the same pool on more than one
host at the same time. Also be careful while bringing dead host online
- either on SAN level make sure it can''t see disks in a pool or boot
to single user and remove /etc/zfs/zpool.cache file so it won''t
automatically try to import pool.

Nothing else special is needed.
