root@blackcube:~/bin # zpool upgrade -a

This system supports ZFS pool feature flags.

Successfully upgraded 'tank' from version 28 to feature flags.
Enabled the following features on 'tank':
  async_destroy
  empty_bpobj
  lz4_compress
  multi_vdev_crash_dump
  spacemap_histogram
  enabled_txg
  hole_birth
  extensible_dataset
  bookmarks
  filesystem_limits

Successfully upgraded 'zfspool' from version 28 to feature flags.
Enabled the following features on 'zfspool':
  async_destroy
  empty_bpobj
  lz4_compress
  multi_vdev_crash_dump
  spacemap_histogram
  enabled_txg
  hole_birth
  extensible_dataset
  bookmarks
  filesystem_limits

If you boot from pool 'zfspool', don't forget to update boot code.
Assuming you use GPT partitioning and da0 is your boot disk
the following command will do it:

        gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

ここで gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0 をしないと、起動できなくなります。

zfsブート出来なく成ってしまった場合、インストーラDVD(FreeBSD 9.3-R DVD-1など)で LIVE CD を起動し、root ログインして

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

する
