    Ok makes sense, but can I just destroy my current pool in the failed state and then import it with the -f option and it should show up with all 4 drives...

    pool: pool02
     state: UNAVAIL
    status: One or more devices could not be opened.  There are insufficient
    	replicas for the pool to continue functioning.
    action: Attach the missing device and online it using 'zpool online'.
       see: http://illumos.org/msg/ZFS-8000-3C
      scan: none requested
    config:

    	NAME        STATE     READ WRITE CKSUM      CAP            Product /napp-it   IOstat mess
    	pool02      UNAVAIL      0     0     0  insufficient replicas
    	  c12d0     ONLINE       0     0     0
    	  c13d0     ONLINE       0     0     0
    	  c14d0     UNAVAIL      0     0     0  cannot open
    	  c15d0     UNAVAIL      0     0     0  cannot open

    Zfs puts identifying information on all the pool disks so that they may be properly imported by pool name without regard for device identifiers.  'zpool import' scans all of the available devices, searching for devices which are in that pool.

    If you don't want to physically move the drives again, then just re-import the pool.

    It is always a good idea to export a pool before moving its drives around and then import the pool afterward.  Usually it just takes a few seconds to import the pool.
