Hi This probably ties together with my previous question about not all masters begin equal. If I am using the concept of "edge" servers in each DC can each server that has been initialized as a multi-master be used in turn to initialize other multi masters? I am testing this at the moment but wanted to clarify this. The documentation refers to a data master and it is not clear whether this is a "relative master" or single server amongst the crowd that is the only authoritative source. dc1 dc2 master01 -> master 02 -> master03 -> master04 Thus, master01 initializes master02. master02 initializes master03 master03 initializes master04 Create repl agreements in the other direction but don't initialize and end up with: dc1 dc2 master01 <-> master 02 <-> master03 <-> master04 Regards ________________________________________________________________________ In order to protect our email recipients, Betfair Group use SkyScan from MessageLabs to scan all Incoming and Outgoing mail for viruses. ________________________________________________________________________
