 # README.
 # 
 # This agent only supports being configured as a multistate Master
 # resource.
 #
 # Slave vs Master role:
 #
 # During the 'Slave' role, galera instances are in read-only mode and
 # will not attempt to connect to the cluster. This role exists as
 # a means to determine which galera instance is the most up-to-date. The
 # most up-to-date node will be used to bootstrap a galera cluster that
 # has no current members.
 #
 # The galera instances will only begin to be promoted to the Master role
 # once all the nodes in the 'wsrep_cluster_address' connection address
 # have entered read-only mode. At that point the node containing the
 # database that is most current will be promoted to Master.
 #
 # Once the first Master instance bootstraps the galera cluster, the
 # other nodes will join the cluster and start synchronizing via SST.
 # They will stay in Slave role as long as the SST is running. Their
 # promotion to Master will happen once synchronization is finished.
 #
 # Example: Create a galera cluster using nodes rhel7-node1 rhel7-node2 rhel7-node3
 #
 # pcs resource create db galera enable_creation=true \
 # wsrep_cluster_address="gcomm://rhel7-auto1,rhel7-auto2,rhel7-auto3" meta master-max=3 --master
 #
 # By setting the 'enable_creation' option, the database will be automatically 
 # generated at startup. The meta attribute 'master-max=3' means that all 3
 # nodes listed in the wsrep_cluster_address list will be allowed to connect
 # to the galera cluster and perform replication.
 #
 # NOTE: If you have more nodes in the pacemaker cluster then you wish
 # to have in the galera cluster, make sure to use location contraints to prevent
 # pacemaker from attempting to place a galera instance on a node that is
 # not in the 'wsrep_cluster_address" list.

 $0 manages a galera Database as an HA resource.
 
 The 'start' operation starts the database.
 The 'stop' operation stops the database.
 The 'status' operation reports whether the database is running
 The 'monitor' operation reports whether the database seems to be working
 The 'promote' operation makes this mysql server run as master
 The 'demote' operation makes this mysql server run as slave
 The 'validate-all' operation reports whether the parameters are valid
