Instruction for test

While galera cluster is up, create a new user for the test

    create user 'testuser'@'%' identified by 'test';

Allow user to log in to a tcp socket

    grant all privileges on 'testuser'@'%';

Stop galera.

    pcs resource disable galera

Once stopped, change /etc/my.cnf.d/galera.cnf to have mysql listen to
port 4242 on an available interface:

    bind_address=0.0.0.0
    port=4242

Then configure /etc/sysconfig/clustercheck to make the resource
agent contact mysqld on the tcp port above. Modify the entries so
that the file looks like:

    MYSQL_USERNAME="testuser"
    MYSQL_PASSWORD="test"
    MYSQL_HOST="127.0.0.1"
    MYSQL_PORT="4242"

(don't set MYSQL_HOST to "localhost" otherwise mysql will try to
connect via UNIX socket)

Start galera again.

    pcs resource enable galera

After all machine are marked as master, verify that mysqld is listening
to port 4242.

    netstat -tnlp | grep mysqld

If so, the test is working as expected since the resource agent polls
mysqld regularly to ensure that galera has started properly and is
still running.

For cleaning up, stop galera, reset the two config files to their
original values, and restart galera. Once started, you can delete the
test user

    drop user 'testuser'@'%';
