Use the -l flag to gpart when creating the partitions. I'm not sure if ther=
e
is a way to label them after the fact. I found it led to a much more
descriptive/reliable pool, as I can plug the disks in anywhere and get the
same results:

  pool: tank
 state: ONLINE
 scrub: none requested
config:

    NAME                  STATE     READ WRITE CKSUM
    tank                  ONLINE       0     0     0
      raidz1              ONLINE       0     0     0
        gpt/samsung15-1   ONLINE       0     0     0
        gpt/samsung15-2   ONLINE       0     0     0
        gpt/samsung15-3   ONLINE       0     0     0
        gpt/samsung15-4   ONLINE       0     0     0
        gpt/seagate15-1   ONLINE       0     0     0
        gpt/seagate15-2   ONLINE       0     0     0

I use the geom name 'gpt/foo' when referring to the disks in zpool. All
works perfectly.

Cheers

Tom
