OpenShift, JBoss EAP 6 - how to re-add MySQL driver - mysql

Question

I have a Java EE 6 application on OpenShift / JBoss EAP 6, which runs out of space regularly due to big server logs.
Recently, the EAP got broken somehow. It can't find the MySQL driver anymore.
The driver is installed when adding the MySQL cartridge (rhc cartridge add mysql-5.1 -a MyApp).
Restarting everything doesn't help.
Deleting the MySQL cartridge and adding it again doesn't help.
Is there a way to add the EAP module without dropping the database?
Why the deployment-scanner subsystem is not found?
This is the related config on OpenShift (standard)
<subsystem xmlns="urn:jboss:domain:deployment-scanner:1.1">
<deployment-scanner path="deployments"
relative-to="jboss.server.base.dir" scan-interval="5000"
deployment-timeout="300" />
</subsystem>

Answer 1

Solved. The JDBC driver module has to be in git repo under .openshift/config/modules/. It wasn't there before and the web worked, so I wonder if something changed in OpenShift.
.openshift/config/modules/com/mysql/jdbc/main/mysql-connector-java-5.1.26-bin.jar
And
.openshift/config/modules/com/mysql/jdbc/main/module.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.mysql.jdbc">
<resources>
<resource-root path="mysql-connector-java-5.1.26-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api" />
<module name="javax.transaction.api" />
</dependencies>
</module>
