> Cleanup stale bind mounts for port mapping isolator during slave recovery.
> --------------------------------------------------------------------------

> Key: MESOS-2547
> URL: https://issues.apache.org/jira/browse/MESOS-2547
> Project: Mesos
> Issue Type: Improvement
> Affects Versions: 0.21.0, 0.21.1, 0.22.0
> Reporter: Jie Yu
> Assignee: Jie Yu
> Fix For: 0.23.0
>
>
> Leaked bind mount under /var/run/netns for port mapping isolator is a known
> issue. There are many ways it can get leaked. For example, if the slave
> crashes after creating the bind mount but before creating the veth, the bind
> mount will be leaked. Also, if the detached unmount does not finish in time
> and the subsequent os::rm fails, the bind mount will be leaked as well.
> Since leaked bind mount is inevitable, we need to clean them up during
> startup (slave recovery).
