When trying to install lustre-client at an environment with IB, I installed first lustre-client-dkms and the build finished with success, when installing lustre-client, it failed due to missing kmod-lustre-client. Basically, lustre-client-dkms is providing lustre-client-kmod while lustre-client requires kmod-lustre-client.

-------------------------------------
[root@hpc-04 iso]# rpm -qp --requires lustre-client-2.9.0-1.el7.x86_64.rpm | grep lustre
kmod-lustre-client = 2.9.0
-------------------------------------
[root@hpc-04 iso]# rpm -q --provides lustre-client-dkms
lustre-client-dkms = 2.9.0-1.el7
lustre-client-kmod = 2.9.0
lustre-client-modules = 2.9.0
-------------------------------------

With the previous version 2.8.0
-------------------------------------
rpm -qp --requires lustre-client-2.8.0-3.10.0_327.3.1.el7.x86_64.x86_64.rpm | grep lustre
lustre-client-modules = 2.8.0
-------------------------------------
rpm -qp --provides lustre-client-dkms-2.8.0-1.el7.noarch.rpm
lustre-client-dkms = 2.8.0-1.el7
lustre-client-kmod = 2.8.0
lustre-client-modules = 2.8.0
