Pune’s KQInfoTech announces beta availability of ZFS file-system for Linux

About an year ago, we had reported that Pune based KQInfoTech is working on porting Sun’s ZFS file system to linux. They have now announced that a “Technology Preview” of the port is now complete, and the ported ZFS for Linux is now available in beta. They are looking for interested folks to try out the beta and help them with finding bugs and other issues.

But first some background, taken from previous PuneTech articles about KQInfoTech.

What is KQInfotech?

KQ InfoTech Logo
KQInfoTech is a Pune company that's trying to combine mentorship programmes for technology students, along with technology services to the industry and open source projects. Click on the logo to see other PuneTech articles on KQInfoTech's various initiatives.

Pune-based KQInfoTech is an organization started by Anurag Agarwal and Anand Mitra, both of whom chucked high-paying jobs in the industry because they felt that there was a desperate need to work on the quality of students that is being churned out by our colleges. For the 2 years or so, they have been trying various experiements in education, at the engineering college level. All their experiments are based on one basic premise: students’ ability to pay should not be a deterrent – in other words, the offerings should be free for the students; KQInfoTech focuses on finding alternative ways to pay for the costs of running the course. As a part of this initiative, they provide services to industry, and take on open source projects, and the students in their mentorship program actually do the work under their guidance.

What is ZFS?

ZFS – the Zettabyte File System – is an enormous advance in capability on existing file systems. It provides greater space for files, hugely improved administration and greatly improved data security. Wikipedia has this to say:

ZFS is a combined file system and logical volume manager designed by Sun Microsystems. The features of ZFS include support for high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, RAID-Z and native NFSv4 ACLs.

Why ZFS on Linux by KQInfotech?

ZFS is arguably one of the best file-systems available today, and Linux is one of the most widely used operating systems for servers by new startups. So, having ZFS available on Linux would be great. And, With many years of experience in Veritas building VxFS, another one of best file-systems in the world, the founders of KQInfoTech do have the technical background to be able to do a good job of this.

At this point, ZFS is not available on Linux. See the Linux section of ZFS entry on Wikipedia for more details.

So what does this port contain?

This port of ZFS is an extension to the port of DMU layer by Brian Behlendorf. We have added the missing ZPL layer to Brian’s port. With this addition it becomes possible to mount the zfs filesystem on linux and leverage ZFS’s features on linux.

What next?

If you’re interested in participating in the beta and helping out, or you’re one of the people whose business would really be helped by having ZFS available on Linux, apply for the beta, or get in touch with KQInfoTech: zfs-query@kqinfotech.com.

Pune’s KQInfoTech is porting Sun’s ZFS File-System to Linux

Pune-based KQInfoTech is working on porting Sun‘s ZFS file-system to the Linux Platform. ZFS is arguably one of the best file-systems available today, and Linux is one of the most widely used operating systems for servers by new startups. So, having ZFS available on Linux would be great. And, With many years of experience in Veritas building VxFS, another one of best file-systems in the world, the founders of KQInfoTech do have the technical background to be able to do a good job of this. Check out the full announcement on their blog:

We have a ZFS building as a module and the following primitive operations are possible.

  • Creating a pool over a file (devices not supported yet)
  • Zpool list, remove
  • Creating filesystems and mounting them

But we are still not at a stage, where we can create files and read and write to them

See the full article, for more details and some interesting issues related to the license compatibility between ZFS and Linux.

On ZFS Technologies

KQInfoTech invites everybody interested in storage and systems to join them in a discussion of ZFS from Sun. This is the second talk in the series. The first talk had discussed various features of ZFS and introduced basic of ZFS, while this seminar we will be attempting to take a deeper plunge into ZFS, trying to look at various aspects of ZFS architecture and getting a better understanding of the same.

However, it is not necesssary to have attended the first seminar to be able to attend this one. There will be a quick refresher for those who missed out on the first one, to bring everyone up to speed on the basics of ZFS.

There are no fees for participation. However in view of limited seats, prior registration is crucial.

Seminar: Introduction to ZFS (Sun/Solaris filesystem) and its features – 7 May

What: Introduction to ZFS and its features
When: 6pm 7th May 2009
Where: Auditorium, Building C, Pune IT Park, Bhau Patil Road, Aundh Road
Fees and Registration: This event is free for all. Please register here if you plan to attend this talk.

The engineers at Sun and members of the open source community have drawn from some of the best practices currently on the market, and contributed their own ideas and expertise to develop a new streamlined, cohesive approach to file system design.  ZFS has made such an impact that other UNIX vendors and open source enthusiasts have already intimated their plans to port it to their own operating systems. With ZFS, Sun addresses the important issues of integrity and security, scalability, and difficulty of administration that often plague other UNIX file systems.

KQInfotech presents a series of talks on the ZFS. We start with introducing the audience to ZFS and its compelling feature set and progressively dive deeper into its actual implementation and internal details over the series. The first talk in the series which will be held on 7th May 2009 will cover the various features of ZFS and will demo a large number of them. The subsequent ones will dive into the internal details of ZFS and its features.

This event is free for all to attend. Please register here if you plan to attend
