[lustre-discuss] ​luster client mount issues

[sohamm]

Hi Rick
Client is configured for IB interface.
in my understanding i can specific the network of choice in the mount
command. tried both tcp and ib. I am still checking on the configurations
as suggested in the forumn. will get back with my findings.

Thanks
