ZFS For Linux Finally Lands In Debian GNU/Linux Repos (softpedia.com)
prisoninmate quotes a report from Softpedia: It took the Debian developers many years to finally be able to ship a working version of ZFS for Linux on Debian GNU/Linux. For those not in the known, ZFS on Linux is the official OpenZFS implementation for Linux, which promises to offer native ZFS filesystem support for any Linux kernel-based operating system, currently supporting Arch Linux, Ubuntu, Fedora, Gentoo, Red Hat Enterprise Linux, CentOS, openSUSE, and now Debian. And it looks like their ZFS for Linux implementation borrows a lot of patches from Ubuntu, at least according to the changelog for zfs-linux 0.6.5.6-2, the version that is now available in the unstable channel for Debian users to install and test. -
Ubuntu Plans To Make ZFS File-System Support Standard On Linux
An anonymous reader writes: Canonical's Mark Shuttleworth revealed today that they're planning to make ZFS standard on Ubuntu. They are planning to include ZFS file-system as "standard in due course," but no details were revealed beyond that. However, ZFS On Linux contributor Richard Yao has said they do plan on including it in their kernel for 16.04 LTS and the GPL vs. CDDL license worries aren't actually a problem. Many Linux users have been wanting ZFS on Linux, but aside from the out of tree module there hasn't been any luck in including it in the mainline kernel or with tier-one Linux distributions due to license differences. -
The State of ZFS On Linux
An anonymous reader writes: Richard Yao, one of the most prolific contributors to the ZFSOnLinux project, has put up a post explaining why he thinks the filesystem is definitely production-ready. He says, "ZFS provides strong guarantees for the integrity of [data] from the moment that fsync() returns on a file, an operation on a synchronous file handle is returned or dirty writeback occurs (by default every 5 seconds). These guarantees are enabled by ZFS' disk format, which places all data into a Merkle tree that stores 256-bit checksums and is changed atomically via a two-stage transaction commit.. ... Sharing a common code base with other Open ZFS platforms has given ZFS on Linux the opportunity to rapidly implement features available on other Open ZFS platforms. At present, Illumos is the reference platform in the Open ZFS community and despite its ZFS driver having hundreds of features, ZoL is only behind on about 18 of them." -
ZFS Hits an Important Milestone, Version 0.6.1 Released
sfcrazy writes "ZFS on Linux has reached what Brian Behlendorf calls an important milestone with the official 0.6.1 release. Version 0.6.1 not only brings the usual bug fixes but also introduces a new property called 'snapdev.' Brian explains, 'The snapdev property was introduced to control the visibility of zvol snapshot devices and may be set to either visible or hidden. When set to hidden, which is the default, zvol snapshot devices will not be created under /dev/. To gain access to these devices the property must be set to visible. This behavior is analogous to the existing snapdir property.'" -
Open Source ExFAT File System Reaches 1.0 Status
Titus Andronicus writes "fuse-exfat, a GPLv3 implementation of the exFAT file system for Linux, FreeBSD, and OS X, has reached 1.0 status, according to an announcement from Andrew Nayenko, the primary developer. exFAT is a file system designed for sneaker-netting terabyte-scale files and groups of files on flash drives and memory cards between and among Windows, OS X, and consumer electronics devices. It was introduced by Microsoft in late 2006. Will fuse-exfat cut into Microsoft's juicy exFAT licensing revenue? Will Microsoft litigate fuse-exfat's developers and users into patent oblivion? Will there be a DKMS dynamic kernel module version of the software, similar to the ZFS on Linux project? All that remains to be seen. ReadWrite, The H, and Phoronix cover the story." -
Running ZFS Natively On Linux Slower Than Btrfs
An anonymous reader writes "It's been known that ZFS is coming to Linux in the form of a native kernel module done by the Lawrence Livermore National Laboratory and KQ Infotech. The ZFS module is still in closed testing on KQ infotech's side (but LLNL's ZFS code is publicly available), and now Phoronix has tried out the ZFS file-system on Linux and carried out some tests. ZFS on Linux via this native module is much faster than using ZFS-FUSE, but the Solaris file-system in most areas is not nearly as fast as EXT4, Btrfs, or XFS."
