Yes, @transport arg here is transport to use for fetching volfile.

Yes, this is correct too.

This is doc written with assumption that rdma would work too.

I think no. To test, you would have to set rdma as only transport option in
glusterd.vol and see what happens in volfile fetch.


IMO, fetching volfile over rdma is an overkill and would not be required.
RDMA should be kept only for IO operations.

We should just remove it from the docs.
