OpenZFS, the container file system comes to Ubuntu Linux

ZFS is a combination of a volume manager (like LVM) and a filesystem (like ext4, xfs, or btrfs).

ZFS one of the most beloved features of Solaris, universally coveted by every Linux sysadmin with a Solaris background.  To our delight, we're happy to make to OpenZFS available on every Ubuntu system.  Ubuntu's reference guide for ZFS can be found here, and these are a few of the killer features:

  • snapshots
  • copy-on-write cloning
  • continuous integrity checking against data corruption
  • automatic repair
  • efficient data compression.

These features truly make ZFS the perfect filesystem for containers.
