Suggested Action for System Administrator

The pool has been written to from another host, and was not cleanly exported from the other system. Actively importing a pool on multiple systems will corrupt the pool and leave it in an unrecoverable state. To determine which system last accessed the pool, run the 'zpool import' command:

# zpool import
  pool: test
    id: 14702934086626715962
state:  ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
        the '-f' flag.

config:

        test              ONLINE
          c0t0d0          ONLINE

# zpool import test
cannot import 'test': pool may be in use from other system, it was last
accessed by 'tank' (hostid: 0x1435718c) on Fri Mar  9 15:42:47 2007
use '-f' to import anyway

If you are certain that the pool is not being actively accessed by another system, then you can use the '-f' option to 'zpool import' to forcibly import the pool.
