Client build fails on Rocky Linux 8.6

[Abhiram Chintangal]

Hi all,

I am currently testing a beegfs instance and on one of my servers that is running Rocky 8.6. At the moment, the client module build fails with the following error:

/etc/init.d/beegfs-client rebuild
- BeeGFS module autobuild

What does this error mean? I am rocky 8.6.

Appreciate any pointers.

Best,

I was able to get this going by going back to a slightly older kernel (4.18.0-348)

and now the client module builds fine.

Best,

This seems to be happening with nearly every 8.x update of the kernel on RHEL and it's getting really annoying (I thought we were supposed to be 'stable' for 10 years). We need to apply updates - because security - but we can't because then we'd lose access to our storage. It's taken months in the past for beegfs to push updates out, but thankfully the community here has been good at coming up with workarounds. Fingers crossed they can again this time.

kernel-lt from elrepo is an alternative.

we completely understand and share your pain with this. Unfortunately, RHEL
kernels can not be considered nearly as stable as they advertise to be.
APIs change with every minor release and patches from newer kernel versions
seem to be backported without any easy-to-follow logic.

In this case though, the fix is very easy. Deleting the line

#include <asm/kmap_types.h>

from /opt/beegfs/src/client/client_module_7/source/os/OsCompat.h and
recompiling the module should do the trick and allow the compilation to
succeed. We will include some updates to support new OS releases (RHEL 8.6,
Ubuntu 22.04) with our next maintenance releases.

Please let me know if there are any issue with the fix proposed above.

Best regards
- Philipp
