Checkdiskusage Option

The  Message Store option enables stopping messages from being delivered to a Message Store  partition when the partition fills more than a  specified percentage of available disk space. If disk usage goes higher than the specified threshold, the store daemon locks the partition and logs a message to the default log files. When disk usage falls below the threshold, the partition is unlocked, and messages are again delivered to the store.

See also the   option which sets a threshold for disk availability below which an alarm message will be sent to the postmaster.

The default value is: 1
