[lustre-discuss] Client 2.12.5 on 4.18.0-193.6.3.el8_2.x86_64 does not load

[Torsten Harenberg]

Dear all,

due to the attacks to HPC centers, we were advised to update the kernels
to the newest version available.

It seems that the Lustre 2.12.5 client does not load on the very recent
CentOS 8 kernel anymore:

[root at arc6 yum.repos.d]# rpm -qa | grep lustre
lustre-client-2.12.5-1.el8.x86_64
lustre-client-dkms-2.12.5-1.el8.noarch

[root at arc6 yum.repos.d]# uname -a
Linux arc6.pleiades.uni-wuppertal.de 4.18.0-193.6.3.el8_2.x86_64 #1 SMP
Wed Jun 10 11:09:32 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

[root at arc6 yum.repos.d]# modprobe -a lustre
modprobe: ERROR: could not insert 'lustre': Invalid argument

[root at arc6 yum.repos.d]# dmesg | tail

Complete de- and re-install does not help.

Is that known? Any advice other than downgrading the kernel again?

Thanks and kind regards

  Torsten
