The same issue affect Lustre 2.12.7

]# modprobe -v lustre      
insmod /lib/modules/3.10.0-1160.25.1.el7_lustre.x86_64/extra/lustre/net/libcfs.ko  
insmod /lib/modules/3.10.0-1160.25.1.el7_lustre.x86_64/extra/lustre/net/lnet.ko networks=o2ib0(ib0)  
insmod /lib/modules/3.10.0-1160.25.1.el7_lustre.x86_64/extra/lustre/fs/obdclass.ko  
insmod /lib/modules/3.10.0-1160.25.1.el7_lustre.x86_64/extra/lustre/fs/ptlrpc.ko

modprobe: ERROR: could not insert 'ptlrpc': Invalid argument

 

removing remove lnet config file will enable the module loading but only tcp

]# cat /etc/modprobe.d/lustre.conf      
options lnet networks=o2ib0(ib0)
