To Harry Mangalam about Gluster/RDMA: make sure these modules are loaded # modprobe -v rdma_ucm # modprobe -v ib_uverbs # modprobe -v ib_ucm To run the subnet manager # modprobe -v ib_umad Make sure libibverbs and (libmlx4 or libmthca) RPMs are installed. I don't understand why they appropriate modules aren't loaded automatically. Could put something in /etc/modprobe.d/ to make this happen maybe? Infiniband should not require troubleshooting after 5-10 years of development, it should just work.
