Hi Simmons,
Thanks for the response. Now I got the confidence that I could deploy Lustre servers on Ubuntu nodes. :)
I am planning to use ZFS as the backing store. So as you mentioned, I should not be having a problem with that.Also, I am planning to use the latest Lustre version - 2.7.
In Lustre.org downloads section for 2.7 release, I see the below:
Can I go with the packages in el6.6 for my deployment?
(I am guessing that 'el' implies Enterprise Linux and 'sles' implies Solaris enterprise linux)
Regards,
Akhilesh.

While not officially supported by Intel I have build Lustre clients to run Ubuntu 14.04 systems. In fact I sent some patches to the Intel master branch to ensure it was supported.
>Though there are enough references on the net showing that clients in the cluster were running Ubuntu, I found it difficult to find much information about servers running on Ubuntu.
Currently the Intel branch can run kernels up to 3.15 so it should work; wink wink. As for server support it depends on what file system back end you want to use. If you run with a ZFS backend then you will have no problem with building lustre servers on Ubuntu. This is not the case for ldiskfs.
>The current Ubuntu 14.04 LTS runs on 3.13.0-49-generic kernel version. I looked up GitHub of the latest kernel version and it shows that the lustre client's code has been incorporated into the kernel. I >am unable to find any information wrt to the servers.
If you use the upstream lustre client some feature of newer lustre servers will not be supported. So for now I would stick to the Intel version.
>So, should I downgrade my kernel to 2.6.X version, recomplie it with the patch and use it for lustre server(s) installation?
Yuck, no.
