Just read about ZFS making it into Ubuntu 19.10 installer as an experimental feature here, sounds pretty cool!
What is ZFS?
ZFS (originally called Zettabyte File System) is a revolutionary filesystem introduced by Sun Microsystems in 2005. ZFS took a few years to crystallise and was eventually shipped with Solaris 10 in 2009. It brought a number of fresh ideas to the world of enterprise storage and ZFS management of filesystems:
- new parity checking modes, even more reliable than RAID5/RAID6
- storage pool that can consist of different sized disks (typically you expect all disks to be of the same size and model)
- self-healing
- extra focus on the data consistency on disk – meaning ZFS caters for typical software and hardware errors
- smart implementation and use of filesystem journaling
- snapshots
- data deduplication
ZFS in Ubuntu 19.10
To be clear, this is big deal not because ZFS is finally available in Ubuntu – it's been around for quite some time thanks to the ZFS on Linux project. But this is the first time native support will be available in Ubuntu installer and also allow you to not just ZFS enable data disks but use it for root partition.
