[Gluster-users] RDMA support in gluster 9

[Saju Mohammed Noohu]

Hi Rupert,

Apologies for the inconvenience, even though this was discussed, somehow it
got missed in official release notes or documentation.

Few old discussions are below:
https://github.com/gluster/glusterfs/issues/692
https://lists.gluster.org/pipermail/gluster-users/2018-July/034400.html

Will surely document this as part of Gluster docs on an appropriate heading.

As evident from the above discussions, we deprecated it since we had no
means to support it. If that changes, we'll be happy to work on re-enabling
it, maybe as a compile-time option.

Thanks
Saju
