swapinfo:

Device          512-blocks     Used    Avail Capacity
/dev/gptid/e4112d88-89ca-11e2-a    8388608    45592  8343016     1%

looks like the gptid is truncated but gpart list shows:

. Name: vtbd0p2
   Mediasize: 4294967296 (4.0G)
   Sectorsize: 512
   Stripesize: 0

   Mode: r1w1e1
   rawuuid: e4112d88-89ca-11e2-a867-3264262b9894
   rawtype: 516e7cb5-6ecf-11d6-8ff8-00022d09712b
   label: (null)
   length: 4294967296
   offset: 82944
   type: freebsd-swap
   index: 2
   end: 8388769
   start: 162

# zpool status
  pool: tank
 state: ONLINE
  scan: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        tank        ONLINE       0     0     0
          vtbd0p3   ONLINE       0     0     0

so I guess it is indeed not zfs, right?
