hi,

according to this page:

# modprobe svc_rdma
FATAL: Module svc_rdma not found.

???

# mount 10.2.2.1:/scratch /mnt -i -o rdma,port=2050
Unsupported nfs mount option: rdma

looks like I definitelly need a rdma-enabled mount, which comes in
http://www.mellanox.com/downloads/NFSoRDMA/OFED-1.2-NFS-RDMA.gz, so:

# mount.rnfs  -h
Usage: mount.rnfs [-o rdma[=host][,...] [-t nfs/nfs4]] <host:path> <mnt_point>

# mount.rnfs -o rdma 10.2.2.1:/scratch /mnt
Doing nfs/rdma mount to 10.2.2.1, mount protocol to 10.2.2.1
nfsmount: Invalid argument

???
