I understand some work is happening on it. Both it and the witness
protocol (a key part of SMB3 clustering) use RPC pipes (which mean a
different thing to what we normally use that term to mean), and Mathieu
and Metze did some work at the interop lab with Microsoft this year.
It is still a long way off however, and really needs a dedicated
engineer on it before a lot of progress is likely.
Much better might be to work out a supported, automated stop-gap for our
admins, that we can support, or to do the research to determine if we
can perhaps safely use a cluster file system if one node is read write
and other nodes are read only. Even just a white paper describing what
the minimum behaviours we need for practical admin use would be helpful.
Some folks have spoken of being able to set read only and read-write
nodes in DFS for example.
