Dependencies of the Threshold and the Retry Interval on Other Properties

The maximum length of time that is required for a single restart of a faulty resource is the sum of the values of the following properties:

To ensure that you allow enough time for the threshold to be reached within the retry interval, use the following expression to calculate values for the retry interval and the threshold:

retry_interval >= 2 x threshold × (thorough_probe_interval + probe_timeout)

The factor of 2 accounts for partial probe failures that do not immediately cause the resource to be failed over or taken offline.
