The default configuration for disk_full_action is SUSPEND, which only suspends audit logging. Suspending audit logging can lead to security problems because the system is no longer keeping track of which syscalls were made.

The security role sets the configuration to SYSLOG so that messages are sent to syslog when the disk is full. If syslog messages are being sent to remote servers, these log messages should alert an administrator about the disk being full. There are additional options available, like EXEC, SINGLE or HALT.

To configure a different disk_full_action, set the following Ansible variable:

security_disk_full_action: SYSLOG

For details on available settings and what they do, run man auditd.conf. Some options can cause the host to go offline until the issue is fixed. Deployers are urged to carefully read the auditd documentation prior to changing the disk_full_action setting from the default.
