[lustre-discuss] Error in compiling lustre-client 2.15.8 on Almalinux 9.8

[Philippe Weill]

hello
this has already been discussed on the list in june

[lustre-discuss] RHEL 9.8 and 10.2 support

you need one patch to compile lustre 2.15.8 with 9.8

from the list :
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.

# rpm -ql lustre-all-dkms-2.15.8-2.el9.src.rpm

you could find my dkms spec  and patch on
