Description

Rather than immediate deletion, the agent performs garbage collection of directories that are no longer deleted based on a combination of time and machine-level disk usage.

There are currently no metrics providing visibility into this process, so monitoring and alerting are not possible. This means errors can go unnoticed, as was the case with MESOS-4979.
