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.

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.
