Importing zfs pools

How to import disks recovered after a reinstall or upgrade. Run zpool import -d against the directory that holds your disk devices.

root@thumper #  zpool import -d /dev/dsk/
  pool: compilers
    id: 12162905211102209752
 state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:

        compilers    ONLINE
          raidz1     ONLINE
            /c0t0d0  ONLINE
            /c1t0d0  ONLINE
            /c4t0d0  ONLINE
            /c6t0d0  ONLINE
            /c7t0d0  ONLINE

Each zpool device will have a unique id. Run zpool import -d $DEVICE_DIRECTORY -f $ID where ID is either the name or the numeric id. I used the numeric id when I did the import. First try without the -f option. If the disks were exported then you won't need the -f. If you're recovering from a system crash or hardware failure it's likely the pool was not exported prior to the crash. -f forces zfs to import the pool even if it thinks it's active.

root@thumper # zpool import -d /dev/dsk -f 12162905211102209752 

If the import was successful zfs won't return any state message. Check that the pool was imported correctly by zpool status.

root@thumper # zpool status
  pool: compilers
 state: ONLINE
 scrub: none requested
config:
