[SOLVED] Docker Service failed to start.

Hey there,

 

You'll have to forgive me I'm really not all that knowledgeable about the inner-workings of Unraid. When I click on the Docker tab I get the above message. If I reboot my server or restart Docker it doesn't come back up. The error I have in syslog is this, not really sure what exactly to do with this.

 

Jul 29 17:59:02 Node1 emhttpd: shcmd (410): /usr/local/sbin/mount_image '/mnt/user/system/docker/docker.img' /var/lib/docker 20

Anyone have a fix without losing data? If I have to, it's alright. Just hoping to avoid it. 

 

Any help is appreciated! Thanks!

You need to re-create the docker image.
