Qian Zhang updated MESOS-8279:
------------------------------
Sprint: Mesosphere Sprint 72
> Persistent volumes are not visible in Mesos UI using default executor on
> Linux.
> -------------------------------------------------------------------------------
>
> Key: MESOS-8279
> URL: https://issues.apache.org/jira/browse/MESOS-8279
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 1.2.2, 1.3.1, 1.4.1
> Reporter: Jie Yu
> Assignee: Qian Zhang
>
> The reason is because on Linux, if multiple containers in a default executor
> want to share a persistent volume, it'll use SANDBOX_PATH volume source with
> type PARENT. This will be translated into a bind mount in the nested
> container's mount namespace, thus not visible in the host mount namespace.
> Mesos UI operates in the host mount namespace.
> One potential solution for that is to create a symlink (instead of just a
> mkdir) in the sandbox. The symlink will be shadowed by the bind mount in the
> nested container, but in the host mount namespace, it'll points to the
> corresponding persistent volume.
