This is JWP and I'm continuing my series on file systems.
|
||
|
|
Today I want to talk about ZFS.
|
||
|
|
With ZFS there's so much information out there and I got some really long things and so
|
||
|
|
I'm hoping that I can keep it from being fragmented, I've read it a couple of times and
|
||
|
|
basically ZFS is a combined file system and logical volume manager designed by Sun Microsystems
|
||
|
|
and the features of ZFS include protection against data corruption,
|
||
|
|
support for high storage capacities, efficient data compression, integration of concepts of
|
||
|
|
file system and volume management. It was one of the first file systems to use snapshots,
|
||
|
|
it has copy on right clones, continuous integrity, checking and automatic repair.
|
||
|
|
It has a feature called RAIDZ and native NFSV4 and something called ACLs.
|
||
|
|
ZFS was originally implemented as an open source software license under a common development
|
||
|
|
and distribution license, CDDL. The ZFS name is a registered trademark of Oracle,
|
||
|
|
of Oracle Corporation. Open ZFS is the umbrella project serving the open source alternative to ZFS.
|
||
|
|
In Linux, ZFS has several Linux implementations despite the fact that the GNU
|
||
|
|
general public license, GPL under which Linux kernel is licensed is incompatible with the
|
||
|
|
common development and distribution license or CDDL under which ZFS is distributed.
|
||
|
|
According to used license model, a single derived work of both projects cannot be legally distributed,
|
||
|
|
so it's not possible to simultaneously meet both license requirements due to ZFS and Linux kernel
|
||
|
|
to include ZFS and Linux kernel. ZFS would have to be cleanly re-implemented and patents
|
||
|
|
may hamper this. This problem is being worked around by providing kernel facilities through
|
||
|
|
separate kernel module, a technical solution for a legal problem that also being employed by
|
||
|
|
vendors and distributors of proprietary hardware drivers. Okay, so now we have something called
|
||
|
|
native ZFS on Linux. A native port of ZFS for the Linux products was produced by
|
||
|
|
the Lawrence Livermore National Laboratory, was released in March of 2013 with the following key
|
||
|
|
events. In 2008, it was prototyped to determine availability. In 2009, the initial ZO VL and Lester
|
||
|
|
support was given. In 2010, development moved from Github. In 2011, the Pasi-X layer was added
|
||
|
|
in 2011, the community, early adopters got it. In 2012, production usage of ZFS happened,
|
||
|
|
and in 2013, it was released as general release. Of the major Linux distributions,
|
||
|
|
Ubuntu and Gen2 have very good support for this flavor of ZFS on Linux, meaning that
|
||
|
|
the required packages can be installed from their own package repositories, and the configuring
|
||
|
|
of ZFS root system is well documented. Open ZFS announced in September of 2013 is a truly
|
||
|
|
open source successor to the ZFS project. Our community brings together developers of
|
||
|
|
I'm going to try to say this. Illy Mouls, FreeBSD, Linux, OSX platforms, and ride range of
|
||
|
|
companies that build products on top of open ZFS. Open ZFS is an outstanding storage platform
|
||
|
|
that encompasses functionality of traditional file systems, volume managers, with more consistent
|
||
|
|
reliability, functionality, and performance across all distributions.
|
||
|
|
Okay, now, I've used ZFS a lot on Open Indiana, and before that on Open Solaris,
|
||
|
|
I've never used it inside of Linux, and after studying in a while, and seeing that it can be
|
||
|
|
done in Ubuntu, I may try when I upgrade my LTS Ubuntu, I may use ZFS since it's in
|
||
|
|
the kernel now, or in the repository to do everything. All right, hey, I hope you enjoyed
|
||
|
|
this little file system thing. As always, I hope you have a great day, and if you need to reach me,
|
||
|
|
I'm at JWP5 at hotmetal.com. Already. Hey, thank you very much for your time.
