OFED 1.5.4 based NFS/RDMA (i.e. xprtrdma) does not run on both platforms. It took a while to understand the setup. I believe issues with RHEL boxes have been fixed - at least iozone runs thru (as client and server) w/out trouble. Now the issue is with this 2.6.38 uOS (as client) that talks to RHEL 6.3 (as server). I don't know much about NFS V4 so the focus is on V3. -- Wendy -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
