>             Project: Mesos
>          Issue Type: Bug
>          Components: agent, containerization
>    Affects Versions: 1.5.1, 1.5.2
>         Environment: DCOS 1.11.6
> Mesos 1.5.2
>            Reporter: Ken Liu

> DCOS service json file is like following. When you type wrong uri, for example, "file://root/test/http.tar.bz2", but the correct one is "file:///root/test/http.tar.bz2". Then it will leave all the persistence mount on the agent, and after gc_delay timeout, the mount path is still there.
> It means if it failed 10 times, then there is 10 persistence volume mount on the agent.
> *Excepted Result: When task is failed,  dangling mount points should be unmounted correctly.*
