I need to unmount because I have an app that will sometimes refuse to start until I unmount and remount.\r\n\r\nWhen I do `umount /mnt/stateful_partition/crouton/chroots/mychroot` i get the message `umount: /mnt/stateful_partition/crouton/chroots/mychroot: not mounted`.  The two errors are contradictory.  One says it is mounted and the other says it isn't.  Could the path in the first message be wrong?\r\n\r\nCan someone tell the right way to unmount a chroot?\r\n\r\n**Edit:** I just realized that a good way to solve this is to find what process is causing the problem and killing it.  Any hints on how to do this?"},"comment":{"url":"https://api.github.com/repos/dnschneid/crouton/issues/comments/134831241","html_url":"https://github.com/dnschneid/crouton/issues/2041#issuecomment-134831241","issue_url":"https://api.github.com/repos/dnschneid/crouton/issues/2041","id":134831241,"user":{"login":"mark-hahn","id":811455,"avatar_url":"https://avatars.githubusercontent.com/u/811455?v=3","gravatar_id":"","url":"https://api.github.com/users/mark-hahn","html_url":"https://github.com/mark-hahn","followers_url":"https://api.github.com/users/mark-hahn/followers","following_url":"https://api.github.com/users/mark-hahn/following{/other_user}","gists_url":"https://api.github.com/users/mark-hahn/gists{/gist_id}","starred_url":"https://api.github.com/users/mark-hahn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mark-hahn/subscriptions","organizations_url":"https://api.github.com/users/mark-hahn/orgs","repos_url":"https://api.github.com/users/mark-hahn/repos","events_url":"https://api.github.com/users/mark-hahn/events{/privacy}","received_events_url":"https://api.github.com/users/mark-hahn/received_events","type":"User","site_admin":false},"created_at":"2015-08-26T04:50:32Z","updated_at":"2015-08-26T04:50:32Z","body":"Thanks ..."}}
