Re: [HPDD-discuss] Installing Lustre on Ubuntu 14.04
Hi,
I am planning to set up a cluster running Lustre FS with all nodes running on Ubuntu 14.04
in our lab and looking for references of any such deployments and possibly pointers in
that direction.
I am aware that officially Lustre supports only Cent OS or RHEL for servers (MDS/OSS). But
I wanted to try with Ubuntu as the OS on all clients, OSS and MDS nodes.
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.
