Thanks Rick! Perhaps just having someone confident in navigating this kind of thing like yourself posting the steps that they have followed to the mailing list would be a public service that would bridge this gap for those less comfortable?

If you need RHEL 9.8 support for Lustre 2.15, you might want to look at https://jira.whamcloud.com/browse/LU-20071.  In particular, there is a proposed patch under review (https://review.whamcloud.com/c/fs/lustre-release/+/65797).  It's a relatively small change and you should be able to apply it (possibly with some modification) without too much difficulty.  The patch is based on the b2_15.  I recently had to rebuild an older version of lustre 2.15 for RHEL 9.8 support, and I was able to modify this patch to do the job.

Thanks for the information. It would be really helpful if there was a clearly described way of how to construct lustre client rpms with the patches for a newer RHEL version. That would indeed allow us to switch to a more recent kernel if security issues require this.
Is that documentation available somewhere? As far as I can see the RHEL 9.8 patches have not been merged into the b2_15 branch. Does a 2.15.9 RC branch exist somewhere?
