--- Comment #4 from Amar Tumballi <atumball at redhat.com> ---
Thanks for the report, but we are not able to look into the RDMA section
actively, and are seriously considering from dropping it from active support.

More on this @

> ‘RDMA’ transport support:
> Gluster started supporting RDMA while ib-verbs was still new, and very high-end infra around that time were using Infiniband. Engineers did work
> with Mellanox, and got the technology into GlusterFS for better data migration, data copy. While current day kernels support very good speed with
> IPoIB module itself, and there are no more bandwidth for experts in these area to maintain the feature, we recommend migrating over to TCP (IP
> based) network for your volume.
> If you are successfully using RDMA transport, do get in touch with us to prioritize the migration plan for your volume. Plan is to work on this
> after the release, so by version 6.0, we will have a cleaner transport code, which just needs to support one type.
