[lustre-discuss] Installation of Lustre server lustre-2.15.5-1.el8

[Andreas Dilger]

I guess you need to explain whether you are trying to install the binary RPM modules (Lustre 2.15.5 RPM packages are available for 4.18.0-553.5.1 at
https://build.whamcloud.com/job/lustre-b2_15/94/arch=x86_64,build_type=server,distro=el8.10,ib_stack=inkernel/artifact/artifacts/RPMS/x86_64/)
or if you are trying to build your own packages using DKMS?

Installing the binary RPMs is *much* easier, in which case you don't need
the DKMS packages at all.

If you are building your own packages then you should use 2.15.8 since it
contains a lot more fixes than installing 2.15.5 on a new system.

Cheers, Andreas
