I would ask why you are installing Lustre 2.2 at this point? That is an old version of Lustre for which no maintenance releases was or will be made. Better to stick with a version like 2.4 or 2.5 which will have maintenance releases with bug fixes. Cheers, Andreas Does i have to use the driver include in RHEL or install mellanox OFED ? If i'm not wrong, RPM from whamcloud are built against infiniband driver included in RHEL6. Is there something specific to install ? Thanks.
