Sounds to be along the lines of what I'd recently asked. http://marc.theaimsgroup.com/?l=openbsd-misc&m=115513950532728&w=2 I haven't found a really great answer to what I was looking at, which amounted to clients trying to access file handles on the new server that were only recognized in the context of the NFS session with the old server. Two ideas that were proposed to me were to use amd to access the NFS exports, and to set the NFS state directory to a shared medium so as to have common state information between nodes (also something about a -n switch to statd on that second one, but I can't find reference to statd anywhere...)
