Ok, here is our use case: We have a small test system running on 3 file servers. cluster/distribute is used to give a flat view of the file servers. Now have the problem that one file server is going to be replaced with a larger one. Therefore we want to put the old file server into read only mode to rsync the files to the new server. Unfortunately this will take ~2days. During this time it would be nice to keep the glusterfs in read/write mode. If I understand it correctly, I should be able to use "lookup-unhashed" to reintegrate the new fileserver in the existing file system, when we switch off the old server.
