Testing with Mariadb GALERA #47

I like so much reactive mysql and I am trying to testing with mariadb galera for high availability and load balancer HAProxy in front ... all nodes have: max_binlog_size = 100M in config file but after a few seconds crash with this error: (perhaps then jumping between different logs nodes it's the problem ...)

Error: ER_MASTER_FATAL_ERROR_READING_BINLOG: log event entry exceeded max_allowed_packet; Increase max_allowed_packet on master; the first event 'mariadb-bin.000001' at 3275, the last event read from 'mariadb-bin.000001' at 3275, the last byte read from 'mariadb-bin.000001' at 3294.

Beware - MariaDB's binary log is not fully compatible with MySQL's, so the binary log following code implemented by the zongji package is getting confused.

If you want Galera, I would recommend that you test Meteor with Persona Server XtraDB cluster, which has a Galera-enabled version:

Thanks vlasky I will try .... but I think the problem is that HAProxy is giving different node log files in each request ... with one mariadb only works great ...
