Description Shehjar Tikoo 2010-08-10 02:57:32 UTC 
I hope it is clear that portmapper will only allow a single GlusterFS (program, version) pair registration on a single machine, preventing us from running multiple bricks on the same server. Unless, every glusterfsd has a different (program, version) pair, but that basically voids the backward compatibility support that was to be brought in using the (program,vers) support.

To do what I think we're trying to do, we'll need a GlusterFS specific portmapper that allows connecting to a specific brick on the server. We could do this through a new tool that uses a triple like (program, vers, brick-id/vol-id or whatever else), instead of a tuple like the (program. version).
