Preparing a disk in FreeNAS using geom commands

Working on disk /dev/da0:

# gpart create -s gpt /dev/da0
# gpart add -t freebsd-swap -b 128 -s 2147483648b da0
# gpart add -t freebsd-zfs -b 4194432 -s 7999415652352b da0

Note: Size (-s) is given in bytes (b)

Operations can be verified

# gpart list da0

Further notes:

  1. Swap partition starts from 128th 512-byte block (beginning of 64kB boundary)
  2. Swap size is 4096*1024*512-byte (4194304 blocks)
