If you are using dkms, you shouldn't install kmod-lustre-*, you should just need zfs-dkms and lustre-zfs-dkms to get the kernel modules you need.

Hi mhanafi, while building zfs, did you try "./configure --with-spec=redhat"?
Hi mdiep and utopiabound, could you please advise?

[Mahmoud Hanafi]

I tried following the steps I got the exact same errors. Tried to compile zfs + lustre from scratch I still got the missing ksym errors.

Hi Mahmoud,
A similar issue was reported in LU-15976 and can be reproduced.
Before the issue is resolved, could you please try the following steps to install the packages? The steps worked in Lustre testing system.

I am attaching output from the install. All the lustre and zfs rpm are in a local_repo downloaded from 

https://downloads.whamcloud.com/public/lustre/latest-feature-release/el8.5.2111/server/RPMS/x86_64/
