[Gluster-users] Missing "gluster volume set-transport" command

Craig,
I have been told that doing that is against best practice although I have yet to see where this best practice is documented. My recently missing files have been blamed on the fact that I deleted and re-created a volume on bricks with existing data. Due to the fact that RDMA seems to be having problems and apparently isn't even known to be working on the OFED that is shipped with any Linux distribution it would be good to have a supported way to switch between RDMA and TCP. Is there any reason that both can't be used? 

Thanks,
Mike
