March 14, 201610 yr I go to Settings>Docker, select Yes, set the image to 10gb, and point it to "/mnt/cache/docker.img". When I hit Apply I see "Starting Docker..." in the bottom left which disappears after a few seconds. Nothing else happens. What am I missing? Here's the log...

March 14, 201610 yr Author No new tab. I also just noticed that the log says the following Mar 13 19:08:07 unSERVER logger: SSD detected: no My cache is a 250gb SSD.
March 16, 201610 yr I'm not an expert with Dockers, but it appears to have issues with the networking and bridging. The syslog terminates just as the dockers are starting to be setup, but the docker log indicates network and bridging issues. Networking appears to be working fine though, including the VPN tunnel, so try turning on bridging in the network settings.
March 16, 201610 yr I also just noticed that the log says the following Mar 13 19:08:07 unSERVER logger: SSD detected: no My cache is a 250gb SSD. I think that refers to the btrfs system just built, docker.img. The system vars show your Cache drive correctly as the Samsung SSD with "[rotational] => 0". All of the other drives are "[rotational] => 1".
March 16, 201610 yr Can you try disabling the use of the OpenVPN plugin temporarily, reboot the system, and try again? Just want to see if there is a conflict there somehow.

Appears OpenVPN is the issue. I now have a Docker tab! Now to figure out why. I attached a new diagnostic zip. unserver-diagnostics-20160316-1712.zip
