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.
