GlusterFS+RDMA has been deprecated 8 years ago in commit

   gluster volfile server fetch happens through unix and/or tcp,
   it doesn't support volfile fetch over rdma. The rdma code may
   actually mislead, so to make sure things do not break, for now
   we fallback to tcp when requested for rdma, with a warning.

   If you are wondering how this worked all these days, its the
   gluster libgfapi code which handles anything other than unix
   transport as socket/tcp, sad but true.

Besides, the whole RDMA subsystem was deprecated in commit
e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma
subsystem") released in v8.2.
