Configure RDMA for Mellanox InfiniBand

[kohcheeguan]

Master Node: beegfs-mgmtd, beegfs-meta, beegfs-client
Storage Node 1: beegfs-storage, beegfs-client
Storage Node 2: beegfs-storage, beegfs-client

OS Version: 20.04.6 LTS
Mellanox Version: 24.10

I have tried to configure beegfs-client for the RDMA for InfiniBand, it prompts as below when I am starting the beegfs-client :

/usr/src/mlnx-ofed-kernel-24.10.OFED.24.10.2.1.8.1/include/linux/compiler_attributes.h:4:10: fatal error: ../../compat/config.h: No such file or directory
4 | #include "../../compat/config.h"
| ^~~~~~~~~~~~~~~~~~~~~~~

Is there any way to regenerate the file "/compat/config.h"?

Cross-posting a relevant answer from this BeeGFS Google Group thread:

Check whether /usr/src/mlnx-ofed-kernel-*/include/ exists and contains the expected OFED headers.
Also, make sure you used --add-kernel-support when installing the Mellanox OFED drivers.

I haven’t hit this exact error before, but in my experience, issues like this usually mean the OFED kernel support wasn’t fully installed so that advice seems sound.
