Use this information to track and troubleshoot the hosting appliance's hard drive resources. If drive usage is consistently high, consider migrating some of the domains or adding another hard drive to the appliance.

You can configure an additional drive to extend the /home directory or to mirror the initial drive (see the Online Guide for detailed instructions).

Note: If you don't have an active RAID array, mirroring the existing drive is the suggested configuration.

To be notified by e-mail when drive usage exceeds the warning or critical threshold, specify the threshold values here, then go to the Alerts page to enable the Drives alert.
