NAME

6       ocf_heartbeat_mariadb - Manages a MariaDB promotable instance
7

SYNOPSIS

9       mariadb [start | stop | status | monitor | promote | demote | meta-data
10               | validate-all]
11

DESCRIPTION

13       Resource script for MariaDB.
14
15       Manages a complete promotable replication setup with GTID, for simpler
16       uses look at the mysql resource agent which supports older replication
17       forms which mysql and mariadb have in common.
18
19       The resource must be setup to use notifications. Set 'notify=true' in
20       the metadata attributes when defining a MariaDB promotable instance.
21
22       The default behavior is to use uname -n values in the change promoted
23       to command. Other IPs can be specified manually by adding a node
24       attribute ${INSTANCE_ATTR_NAME}_mysql_master_IP giving the IP to use
25       for replication. For example, if the mariadb primitive you are using is
26       p_mariadb, the attribute to set will be p_mariadb_mysql_master_IP.
