Could you help me to solve the problem, or give me some suggestion? Thanks a lot!

barakmich commented 8 years ago

Ah, I bet I know why. Ubuntu 14.04 used Upstart, and right now the volume mount plugin uses systemd to manage its lifecycle. Should add that notification to the guide.

@barakmich Thanks a lot. I will change my OS to coreos.
