We build our own kernels from vanilla with some extra flavors, our clients currently run kernel 4.2.8 (+patch for COW and other additions).
On our clients we aren't running RHEL but afaik it should be possible to compile your own vanilla kernel for RHEL just like it is possible to compile it for other distros and since that is possible there should be no issue running a Lustre 2.8 client on RHEL 7.3 or on any other distro that allows your own kernel.

HTH,

Are you talking vanilla kernels or Red Hat kernel? Red Hat can sometimes include something from a more current kernel than their baseline that needs to be adapted to and I think that is what Andreas is suggesting happened with RHEL 7.3. Or have you tried it and found otherwise ?

Normally I don't contradict, but he's asking about the client as far as I understand.

The client can be built from source for any kernel* up to 4.2 (lustre 2.8) and Lustre 2.9 I believe was patched to work with newer kernels but we haven't tested yet.

* not quite any, you probably need at least kernel 2.6.X but that is still almost any kernel released in the past few years.

The Lustre 2.8.0 release was only built with CentOS 7.2, and AFAIK there are a number of patches needed to build against CentOS 7.3 which are included in the Lustre 2.9.0 release.

Hi Lustre experts

I was wondering the possibility to build lustre client of version 2.8.0 with CentOS 7.3 “3.10.0-514.2.2.el7.x86_64” from the SRPM of “
lustre-client-2.8.0-3.10.0_327.3.1.el7.x86_64.src.rpm
”.

Somehow there are some modifications in the kernel source. Just like the report on the mail archive (see below).

https://www.mail-archive.com/lustre-discuss@lists.lustre.org/msg13167.html

 

Could we build the rpm files of lustre client 2.8.0 with git source successfully?

I try the SRPM of lustre 2.9.0 with CentOS 7.3.1611. It works.  

Thanks in advances.

 

Best regards,

James J.-C. CHEN (Ph.D)
