my rhel8 system is actually an Alma Linux 8.5 installation, this is the first time the compatiblity to an alleged rhel8.5 software fails...


The system is running kernel '4.18.0-348.2.1.el8_5'
This version string can also be found in the package names in
https://downloads.whamcloud.com/public/lustre/lustre-2.15.0/el8.5.2111/server/RPMS/x86_64
- this is usually a good sign.

However, installation of kmod-lustre-2.15.0-1.el8 yields the well known "depmod: WARNINGs", like
> /lib/modules/4.18.0-348.2.1.el8_lustre.x86_64/extra/lustre/net/ko2iblnd.ko needs unknown symbol __ib_alloc_pd


The kernel from downloads.whamcloud.com/public/lustre/lustre-2.15.0/el8.5.2111/server/RPMS/x86_64 identifies itself as "CentOS" and does not want to boot - no option either.


Any hints how to proceed?

The ko2iblnd module is built against the in-kernel OFED, so if you are using MOFED you will need to rebuild the kernel modules themselves.  If you don't use IB at all you can ignore these depmod messages.

Cheers, Andreas
