--------------------------------

             Summary: Incorrect agent gc could empty up entire persistent volume content
                 Key: MESOS-7366
                 URL: https://issues.apache.org/jira/browse/MESOS-7366
             Project: Mesos
          Issue Type: Bug
            Reporter: Zhitao Li
            Assignee: Jie Yu
            Priority: Critical


When 1) a persistent volume is mounted, 2) umount is stuck or something, 3) executor directory gc being invoked, agent seems to emit a log like:

```
 Failed to delete directory  <executor_dir>/runs/<uuid>/volume: Device or resource busy
```

The triggering environment is a custom executor w/o rootfs image.

Please let me know if you need more signal.
