Scheduling File System Updates

When the sites' file systems are updated with recent RPM updates, Parallels Pro Control Panel runs in maintenance mode. During the maintenance mode, the sites hosted on the server are inaccessible. It is recommended that you schedule this maintenance during a period of low activity.

You can schedule the maintenance to occur periodically to ensure that the sites' file systems are updated with the latest files. You can schedule this update process by running the scheduleMaintenance script as the root user. The scheduleMaintenance script schedules the execution of the synchronizeFST script by updating the cron file with the schedule settings you specify for the scheduleMaintenance script. You can view the existing schedule information in the file /etc/cron.d/scheduleMaintenance.

The following table lists the options you can use with the script.
