Description

Hello, I am trying to install lustre on our lnet routers which have connectx-5 cards installed in them using dkms on Centos 7.8 with kernel 3.10.0-1127.19.1.el7.x86_64. Also Mellanox just released their latest driver version OFED-5.2-1.0.4 yesterday Jan 4, 2021. When dkms tries to compile lustre, it fails with the following at end:

configure: LNet kernel checks

Also, I did verify that the MLNX rpms that are supposed to be installed, are installed.
On the machine I am trying to install on, I did check and ibstat states that both the cards have an active LinkUP:

Any ideas how to get this to work ?

Thanks,
