KQ ZFS no longer actively being worked on – ZFS on Linux

Gerard — Tue, 04 Oct 2011 06:18:01 +0000

The ZFS file system didn’t get ported to Linux for a long time as its source-code is distributed under the CDDL license, which is incompatible with the GNU GPL, therefore making it impossible to integrate it into the mainline Linux kernel. However, KQ Infotech, and Indian tech company, ported the ZFS file-system to Linux as an out-of-tree kernel [...]

High-availability storage with GlusterFS on Ubuntu

Gerard — Fri, 15 Jan 2010 12:49:13 +0000

This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 9.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 9.10 as well) will be able to access the storage [...]

FreeNAS Bash script for ZFS scrubbing

Gerard — Sat, 29 Aug 2009 19:47:59 +0000

Gimpe has put together a bash script to automatically run a script at predifined intervals to do a scrub on each ZFS pool. Please note, this will only run on FreeNAS 0.7 (not on the 0.6x series as it doesn’t support Sun’s Zetabyte Filesystem (ZFS).

btrfs: a brief comparison with ZFS

Gerard — Fri, 31 Jul 2009 21:52:44 +0000

lwn.net has an overview of the history of the btrfs filesystem (wikipedia link). He also touches on the difference and similarities between btrf and ZFS, Sun’s Zetabyte File System, something that I was most intersted in: “People often ask about the relationship between btrfs and ZFS. From one point of view, the two file systems [...]
