[lustre-discuss] Getting started with Lustre on RHEL 8.8

[Andreas Dilger]

Hello,
The preferred path to set up Lustre depends on what you are planning to do with it?  If for regular usage it is easiest to start with RPMs built for the distro from https://downloads.whamcloud.com/public/lustre/latest-release/<https://downloads.whamcloud.com/public/lustre/latest-release/el8.8/server/RPMS/x86_64/> (you can also use the server RPMs for a client if you want).

The various "client" packages for RHEL, SLES, Ubuntu can install directly on the vendor kernels, but the provided server RPMs also need the matching kernel.  You only need one of the ldiskfs (ext4) or ZFS packages, not both.

It isn't *necessary* to build/patch your kernel for the server, though the pre-built server download packages have patched the kernel to add integrated T10-PI support (which many users do not need).  You can get unpatched el8 server RPMs directly from the builders:
https://build.whamcloud.com/job/lustre-b2_15-patchless/48/arch=x86_64,build_type=server,distro=el8.7,ib_stack=inkernel/artifact/artifacts/

If you plan to run on non-standard kernels, then you can build RPMs for your particular kernel. The easiest way is to just rebuild the SPRM package:

If you want to do Lustre development you should learn how to build from a Git checkout:

Cheers, Andreas

Hi, I am setting up a lab environment for lustre. I have 3 VMs of RHEL 8.8, I have studied the documentation but it does not provide detail for el 8 rather el 7. Please guide me how to start
Thank You
