> Support mount propagation for host volumes.

> Key: MESOS-7306
> URL: https://issues.apache.org/jira/browse/MESOS-7306
> Project: Mesos
> Issue Type: Improvement
> Components: containerization
> Reporter: Jie Yu
> Assignee: Jie Yu
> Labels: mesosphere, storage
>
> Currently, all mounts in a container are marked as 'slave' by default.
> However, for some cases, we may want mounts under certain directory in a
> container to be propagate back to the root mount namespace. This is useful
> for the case where we want the mounts to survive container failures.
> See more documentation about mount propagation in:
> https://www.kernel.org/doc/Documentation/filesystems/sharedsubtree.txt
> Given mount propagation is very hard for users to understand, probably worth
> limiting this to just host volumes because we only see use case for that at
> the moment.
> Some relevant discussion can be found here:
