Is that read/write (RW) replication? That's a difficult problem to solve. Do you achieve it through the filesystem or the database (ie: replaying the commands)? Are both replicas (or master + replica(s)) RW at the same time? Or, one is RW and others RO, and if the RW goes away, one of the RO replicas is promoted (automatically?) to RW status? Any pointers/URLs for how-to documents would be much appreciated. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
