| Is it possible to provide a single volume file to serve a gluster file system over ib-verbs and tcp | simultaneously? Yes. Its possible. Run 'glusterfs-volgen' with '--transport tcp,ib-verbs' as option. It will generate the required export volumes. (Technically, you have to define two protocol/server volume with same options other than 'transport-type' which will be 'tcp' for one, and 'ib-verbs' for another). Regards, Amar
