I have an issue on one of my machines in my cluster where nothing will start. I've tracked this down to systemd and I'm unsure how to go about finding the root of the issue from here. I am able to mount nfs mounts from the command line without issue, but if I try to use the systemd unit file systemctl just hangs forever. Here is the debug output I get from trying to run the mount:

sudo SYSTEMD_LOG_LEVEL=debug systemctl start docker_repo.mount

motdgen seems to be running ok, but I get nothing but hangs for anything that I try.

sudo systemctl status docker_repo.mount

● docker_repo.mount - /docker_repo

Loaded: loaded (/etc/systemd/system/docker_repo.mount; static; vendor preset: disabled)

Active: inactive (dead) since Mon 2015-03-23 21:33:32 UTC; 8s ago

Where: /docker_repo

What: server:/docker_repo

Mar 23 21:02:16 coreos_cluster01 systemd[1]: Mounted /docker_repo.

The successful mount is from my command line mount check. Anyone know where to begin here? Should I just nuke it from orbit and start over?
