Is the rootvolume not replicated? Not unless you recreate the rootvolume. At the time the volume is created the 'replication group' is specified (the E0000100 number). createvol_rep uses that number to find on which servers the volume replicas should be located and creates those replicas. Their volume-ids and other information is then written to the VRList. The VRList file is then converted to the binary VRDB (volume replication database) which is queried by the clients. When you add a new server, it doesn't have volume replicas for existing volumes and none of the VRDB entries actually refer to anything on the new server. At some point in the future we will be able to grow the replication group for an existing volume (we're getting closer every release) but for now you have to create new volumes for the new replication group.
