Artem Harutyunyan updated MESOS-4291: ------------------------------------- Sprint: Mesosphere Sprint 26, Mesosphere Sprint 27, Mesosphere Sprint 28 (was: Mesosphere Sprint 26, Mesosphere Sprint 27) > fs::enter(rootfs) does not work if 'rootfs' is read only. > --------------------------------------------------------- > > Key: MESOS-4291 > URL: https://issues.apache.org/jira/browse/MESOS-4291 > Project: Mesos > Issue Type: Bug > Reporter: Jie Yu > Assignee: Jie Yu > Labels: mesosphere, unified-containerizer-mvp > > I noticed this when I was testing the unified containerizer with the bind > mount backend and no volumes. > The current implementation of fs::enter will put the old root under > /tmp/._old_root_.XXXXXX in the new rootfs. It assumes that /tmp is writable > in the new rootfs, but this might not be true, especially if the bind mount > backend is used. > To solve the problem, what we can do is to mount tmpfs to /tmp in the new > rootfs and umount it after pivot_root. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
