Pawel Jakub Dawidek has added the latest open-source ZFS file system version (28) to FreeBSD Current.

Few new things available now are:

  • Data deduplication (info)
  • Triple parity RAIDZ (RAIDZ3).
  • zfs diff (info)
  • zpool split (info)
  • Snapshot holds (info)
  • zpool import -F. Allows to rewind corrupted pool to earlier transaction group
  • Possibility to import pool in read-only mode

PJD has done a great job adding these features to FreeBSD. Is FreeBSD going to be the future of FreeBSD? Some think so: FreeBSD wordt the toekomst van ZFS (Dutch) – (translate)
