            Stopping the server with the full disk allows MaxScale to detect it.

            For GaleraMon, the best solution to this would probably be to change Galera, so that it terminates a node if the node's disk fills up. There is a feature request about this:

            It wouldn't be enough for MaxScale to stop routing queries to the node with the full disk. Since all transactions have to be certified by all nodes, the node will continue causing problems for the cluster until it is removed from the cluster. Therefore, the best solution would probably be for Galera to auitomatically remove the node from the cluster.
