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:

# 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?
