Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-Virus-Scanned: Maia Mailguard 1.0.1 X-Spam-Status: No, hits=-1.18 tagged_above=-10 required=5 tests=BAYES_00=-1.9, SARE_SPEC_REPLICA=0.72 X-Spam-Level: X-Archive-Number: 201108/101 X-Sequence-Number: 38088 Hi All; I have a client that wants the following: - 2 masters (master to master replication) - multiple read only slaves off each master - the ability to failover in case of a master node failure to include re-directing the slaves off the failed master to now point to the remaining active master Questions: - Is Bucardo the only viable master to master solution? - Can I setup HOT standby's or SLONY off of a Bucardo master? - Can I shift a slave's 'master' without a full reset?
