Build and install Lustre, encounter issue as attachment "lustre-package-install-error"

Mainly about much of the ksym lacking.

Like:

Hi Kevin,

Lustre kernel module RPM includes dependencies to some kernel symbols. This dep-symbols are usually provided by the kernel RPM itself. This helps picking the right kernel dependency, especially on RHEL-like system.

In this case, you build a custom kernel yourself and I'm pretty sure your kernel rpm do not provide this extra Provides. You can check that in two ways:

• First, extract the provides list from your kernel package: –

 

rpm -q --provides kernel-4.18.0-80.11.2.el8_lustre.aarch64

• Second, try to force install your Lustre RPMS ignoring these missing deps. It should be usable.

Is there any reason why you patched your kernel? A non-patched kernel is good enough for most usage and would avoid this issue.
