HI,

just a comment on the client side Ubuntu Lustre kernel module.

I am running Lustre 2.6 in production on Centos 6 Servers and Trusty Ubuntu client systems.

I have nothing to add regarding the server setup, but be careful with the Trusty Lustre kernel module.
Have a look at the mail I have send to this list on 09/10/2014: subject "LNET: out of memory at /build/buildd/linux-3.13.0/drivers/staging/lustre/"

The Ubuntu Lustre kernel module was quite unstable at that time and it seemed Lustre patches have not been added to the Ubuntu stock kernel.
The problem has been resolved by building a custom vanilla 3.12.30 kernel and building Lustre from source. Since then, all Trusty clients are stable.

just in case.

-Nico

Thanks Eli.

I was trying to build the server on Ubuntu and couldn't find much help. Yes. I agree that not much work is needed for client since the client module is already incorporated as part of the kernel.

Shifted to CentOS now due to time constraints for my project. If James could provide the details on how to do that, I would be glad to test during my spare time and post the details/results to the community.

Regards,
Akhilesh.

Sorry to hear :(

For clients you don't need anything special, the stock kernel should
suffice (though you may want a newer kernel for bugfixes etc).

For the servers I can't tell you (yet), but it seemed from James' post
that he built that successfully...

Eli

PS: this is the ./configure we use to build our clients:

./configure --disable-modules --disable-server --enable-client
--prefix=/usr/local/lustre/[version]
