Hello, I have an issue with the following architecture: 1. master 3. slaves with streaming replication (used for backup and read-only queries)
When the master goes offline, 1 of the slaves must become master. Thus I am creating trigger_file and the slave becomes the master. The problem is that the other 2 slaves are using timeline 1, when the new master is in a different universe. How can I easile migrate the 2 slaves on the new master without creating a new base backup (which unfortunately takes too long as the databases contain arround 200GB)? Shoud I use pg_resetxlog? If yes, what is the command? The problem is that the slaves are used for reading and I really need to have them synced with the new master in matter of seconds not minutes (the slaves are distributed globally - 2 in us, 1 in europe, 1 in asia). Thank you. PS: you postgresql guys did a magnificent job with 9.0 (streaming and performance). you guys rock. -- Best regards, Dragos Moinescu -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
