Create basic directory structure
All new features specs go into in_progress directory.
Once signed off, it should be moved to done directory.
For now,
This change moves all the Gluster 4.0 feature specs to
in_progress. All other specs are under done/release-version.
More cleanup required will be done incrementally.

For many users, having a separate -network exclusively for servers is highly desirable for both performance -reasons (segregating administrative traffic and/or second-hop NFS -traffic from ongoing user I/O) and security reasons (limiting -administrative access to the private network). While such configurations -can already be created with routing/iptables trickery, full and explicit -support would be a great improvement. - -Owners ------- - -Jeff Darcy <jdarcy@redhat.com> - -Current status --------------- - -Proposed, awaiting summit for approval. - -Related Feature Requests and Bugs ---------------------------------- - -One proposal for the high-level syntax and semantics was made [on the -mailing -list](http://www.gluster.org/pipermail/gluster-users/2014-November/019463.html). - -Detailed Description --------------------- - -At the very least, we need to be able to define and keep track of -multiple names/addresses for the same node, one used on the back-end -network e.g. for "peer probe" and and NFS and the other used on the -front-end network by native-protocol clients. The association can be -done via the node UUID, but we still need a way for the user to specify -which name/address is to be used for which purpose. - -Future enhancements could include multiple front-end (client) networks, -and network-specific access control. - -Benefit to GlusterFS --------------------- - -More flexible network network topologies, potentially enhancing -performance and/or security for some deployments. - -Scope ------ - -### Nature of proposed change - -The information in /var/lib/glusterd/peers/\* must be enhanced to -include multiple names/addresses per peer, plus tags for roles -associated with each address/name. - -The volfile-generation code must be enhanced to generate volfiles for -each purpose - server, native client, NFS proxy, self-heal/rebalance - -using the names/addresses appropriate to that purpose. - -### Implications on manageability - -CLI and GUI support must be added for viewing/changing the addresses -associated with each server and the roles associated with each address. - -### Implications on presentation layer - -None. The changes should be transparent to users. - -### Implications on persistence layer - -None. - -### Implications on 'GlusterFS' backend - -None. - -### Modification to GlusterFS metadata - -See [nature of proposed change](#Nature_of_proposed_change "wikilink"). - -### Implications on 'glusterd' - -See [nature of proposed change](#Nature_of_proposed_change "wikilink"). - -How To Test ------------ - -Set up a physical configuration with separate front-end and back-end -networks. - -Use the new CLI/GUI features to define addresses and roles split across -the two networks. - -Mount a volume using each of the several volfiles that result, and -generate some traffic. - -Verify that the traffic is actually on the network appropriate to that -mount type. - -User Experience ---------------- - -By default, nothing changes. If and only if a user wants to set up a -more "advanced" split-network configuration, they'll have new tools -allowing them to do that without having to "step outside" to mess with -routing tables etc. - -Dependencies ------------- - -None. - -Documentation -------------- - -New documentation will be needed at both the conceptual and detail -levels, describing how (and why?) to set up a split-network -configuration. - -Status ------- - -In design. - -Comments and Discussion ------------------------ - -Some use-cases in [Bug 764850](https://bugzilla.redhat.com/764850). -Feedback requested.
