David, The whole point of clustering is to remove single points of failure. How does one set up bucardo on multiple nodes so that you don’t end up with the only bucardo daemon offline, and effectively without a cluster?
Tyler Hains Independent Consultant From: [email protected] [mailto:[email protected]] On Behalf Of David Christensen Sent: Monday, January 08, 2018 5:26 PM To: ning chan <[email protected]> Cc: [email protected] Subject: Re: [Bucardo-general] Multi-Master configuration in Bucardo Hi Ning, You should only run the bucardo commands on a single node (the server that you are running the “bucardo daemon” on). That node can be, but need not be, one of the database nodes. There is a single Bucardo daemon, not one that runs on each nose, so it is unnecessary (and unadvised) to have them running on each node. When setting up a multi-master database cluster, you will just add each of the databases in the database groups as sources; it will work out that you mean to do a multi-master cluster. Updating your example: ./bucardo add db mmdb01 dbname=test host=mmdb01 user=bucardo ./bucardo add db mmdb02 dbname=test host=mmdb02 user=bucardo ./bucardo add db mmdb03 dbname=test host=mmdb03 user=bucardo ./bucardo add all tables -T test1 herd=mmdb_herd ./bucardo add dbgroup mmdb_db_group mmdb01:source ./bucardo add dbgroup mmdb_db_group mmdb02:source ./bucardo add dbgroup mmdb_db_group mmdb03:source ./bucardo add sync mmdb_sync herd=mmdb_herd dbs=mmdb_db_group autokick=0 ./bucardo validate mmdb_sync ./bucardo update sync mmdb_sync autokick=1 ./bucardo start As far as the stalling behavior, that is currently how Bucardo is written, so this is a known issue.
