10 | validate-all]
11
13 Resource script for MariaDB.
14 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 The resource must be setup to use notifications. Set 'notify=true' in
20 the metadata attributes when defining a MariaDB promotable instance.
21 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.

174 The following is an example configuration for a mariadb resource using
175 the crm(8) shell:
176 primitive p_mariadb ocf:heartbeat:mariadb \
178 params \
179 node_list=string \
180 op monitor depth="0" timeout="30s" interval="20s" \
181 op monitor role="Promoted" depth="0" timeout="30s" interval="10s" \
182 op monitor role="Unpromoted" depth="0" timeout="30s" interval="30s"
183 ms ms_mariadb p_mariadb \
185 meta notify="true" interleave="true"
