Is the volume's transport type only 'rdma' ? or 'tcp,rdma' ? If its only 
'rdma', then appending ".rdma" to volume name is not required. The 
appending of ".rdma" is only required when there are both type of 
transports on a volume (ie, 'tcp,rdma'), as from the client you can 
decide which transport you want to mount.

default volume name would point to 'tcp' transport type, and appending 
".rdma", will point to rdma transport type.

Hope that is clear now.
