ZFS revision 28 in 9-CURRENT

ZFS pool revision 28 has been recently imported into FreeBSD 9-CURRENT. Among others, things to enjoy:

  • Data deduplication
  • RAID triple parity -- RAIDZ3
  • zfs diff command (describes differences between snapshots)
  • zpool split command (splitting mirrored pools)
  • Snapshot holds (e.g. keeping old snapshots when receiving from a source that removed them)
  • zpool import -F (allows to rewind corrupted pool to earlier transaction group)

FreeBSD 8.2 goodies

The FreeBSD 8.2 release brings one some very interesting features for the enterprise environment:

  • Xen HVM support in FreeBSD/amd64 and Xen PV support in FreeBSD/i386 improved
  • ZFS on-disk format updated to version 15
  • KVA memory space sizing for FreeBSD/amd64 (reduces “kmem_map too small” panics when using ZFS)
  • GPT (GUID Partition Table) support improvements
  • aibs(4) driver has been added for hardware sensors support in ASUS motherboards

This is the first public manifesto for the project and thus may be further developed/changed in the future.
