soon ZFS under Linux

I am still testing my NAS system (seven 300Gb disks) and while testing OpenSolaris (under Belenix), and Googling I found that page:

This blog is about the Google Summer of Code project "ZFS filesystem for FUSE/Linux"

For all of You that do not know what FUSE is, FUSE is the Filesystem in Userspace #Linux kernel module. This module allows nonprivileged users to create their own filesystems without writing any kernel code.

While ZFS has many features which can benefit all kinds of users – from the simple end-user to the biggest enterprise systems:

  • Provable integrity – it checksums all data (and meta-data), which makes it possible to detect hardware errors (hard disk corruption, flaky IDE cables..). 
  • Atomic updates – means that the on-disk state is consistent at all times, there’s no need to perform a lengthy filesystem check after forced reboots/power failures.
  • Instantaneous snapshots and clones – it makes it possible to have hourly, daily and weekly backups efficiently, as well as experiment with new system configurations without any risks.
  • Built-in compression, encryption
  • Highly scalable
  • Pooled storage model – creating filesystems is as easy as creating a new directory. You can efficiently have thousands of filesystems, each with it’s own quotas and reservations, and different properties (compression algorithm, checksum algorithm, etc..).
  • Built-in stripes (RAID-0), mirrors (RAID-1) and RAID-Z (it’s like software RAID-5, but more efficient due to ZFS’s copy-on-write transactional model). 
  • Variable sector sizes, adaptive endianness etc…

In fact this is a sponsored Google summer of code project. Note that Apple is also currently porting ZFS under OS-X. That could mean that ZFS could be mainstream in a future not far away than 2 years.

And I expect to test RAID-Z…For those interested by RAID-Z raw performances, You can read this highly technical blog entry: WHEN TO (AND NOT TO) USE RAID-Z

Sun expect to have a stable ZFS version by June 2006.
