[lustre-discuss] lustre-client-dkms-2.15.4 is still checking for python2

[Andreas Dilger]

I've cherry-picked patch https://review.whamcloud.com/53947 "LU-15655<https://jira.whamcloud.com/browse/LU-15655> contrib: update branch_comm to python3" to b2_15 to avoid this issue in the future.  This script is for developers and does not affect functionality of the filesystem at all.

Cheers, Andreas

I found the file that still references python2.
The file contrib/scripts/branch_comm contains ‘#!/usr/bin/env python2’
After changing that to python3 and building the dkms-rpm I can install the generated lustre-client-dkms-2.15.4-1.el9.noarch.rpm on AlmaLinux 9.3

I have no idea what that script does, or if it functions with python2 instead of python2 as env.

Installing the DKMS is fine.  You can ignore the python2 dependency.

If you can debug *why* it is depending on python2 then a patch would be welcome.  Please see:

I have always installed both… Hasn’t caused issues luckily.

The binary installs, but the dkms version insists it needs python2.
If I use the binary, it will break with every minor kernel version update right? I’ll have to wait with updating the kernel until the lustre client catches up?

Thanks,

It looks like there may be a couple of test tools that are referencing python2, but it definitely isn't needed
for normal operation.  Are you using the lustre-client binary or the lustre-client-dkms?  Only one is needed.

For the short term it would be possible to override this dependency, but it would be good to understand
why this dependency is actually being generated.

FYI
It seems that lustre-client-dkms-2.15.4 is still checking for python2 and does not install on AlmaLinux 9.3

# dnf --enablerepo=lustre-client install lustre-client lustre-client-dkms

Error:
Problem: conflicting requests

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

According to the changelog this should have been fixed (https://wiki.lustre.org/Lustre_2.15.4_Changelog<https://urldefense.com/v3/__https:/wiki.lustre.org/Lustre_2.15.4_Changelog__;!!OUGTln_Lrg!UFvRWmjp6SVJYjhBBuGKITiKvpICPOjXV_6cu90wK4MQf_w6X1xHXFcuxOYFOaIXkwOtBMGE6qXh1oyHJPdWyA$>).
