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 [...]

Run ZFS on Linux

Gerard — Tue, 08 Feb 2011 23:01:34 +0000

Although ZFS exists in an operating system whose future is at risk, it is easily one of the most advanced, feature-rich file systems in existence. It incorporates variable block sizes, compression, encryption, de-duplication, snapshots, clones, and (as the name implies) support for massive capacities. Get to know the concepts behind ZFS and learn how you [...]

zxfer – a handy ZFS tool

Gerard — Thu, 03 Feb 2011 22:54:41 +0000

zxfer, available under the BSD license, is a really handy and much promising ZFS tool. It transfer ZFS filesystems, snapshots, properties, files and directories, which can be done with a single command, while having similar end-to-end assurance of data integrity as the ZFS filesystem itself. Some more detailed features are: recursive transfer of filesystems minimal dependencies. [...]

ZFS data integrity tested

Gerard — Sat, 27 Feb 2010 08:39:35 +0000

Robin Harris over at the ZDnet.com Storage Bits blog analyses a new UW-M paper analyzing the fault tolerance claims of ZFS: “File systems guard all the data in your computer, but most are based on 20-30 year old architectures that put your data at risk with every I/O. The open source ZFS from Sun Oracle [...]

FreeNAS on Debian = no ZFS

Gerard — Fri, 27 Nov 2009 22:44:46 +0000

Due to license restrictions, Sun’s Zetabyte File System (ZFS) cannot be ported over to Linux. Though many are welcoming a Debian-based FreeNAS, the absense of ZFS gives reason for great disappointment: ZFS was the only reason to use FreeNAS. That was the USP of the product. No ZFS in Linux means I’ll just migrate to [...]

Apple shuts down ZFS open source project

Gerard — Wed, 18 Nov 2009 22:48:29 +0000

Apple‘s efforts to support the development of ZFS, an advanced file system originally created by Sun, were officially terminated today in a notice posted by MacOS Forge. The tersely worded message only stated that “The ZFS project has been discontinued. The mailing list and repository will also be removed shortly.” … Apple’s interest in porting [...]

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 [...]

SUN ZFS Triple-Parity RAID-Z

Gerard — Wed, 29 Jul 2009 09:57:04 +0000

The standard in the RAID industry for storage is RAID-6, with recovery from a double drive failure. But it’s not going to be good enough as disk capacities increase, prolonging failed disk rebuild times and so lengthening the window of unrecoverable failure if a third disk fails before the recovery from a double drive failure is [...]
