My Docker tab is missing from the UnRAID server page. I also have an appdata Share drive on Disk 2 that I cannot get rid of. I don't mind losing the Plex Media Server appdata since I can just re-install and re-set up the Plex docker. How do I get my Docker tab back?

I expect that your appdata share was supposed to be on the cache drive? If that is the case, you probably forgot to set the appdata share to cache only.

 

Rename your appdata share on disk 2 to appdataold. If its visible from the GUI, User Shares you can do it there.  Then in User Shares add a new share, Share name: appdata then set Use cache disk: Only and the apply.

 

Next step is either to copy all files from appdataold to appdata. This is best done from the command line with Midnight Commander so if you feel comfortable with that login with Putty (or whatever you use) and type MC that is the inbuilt file manager and copy everything (folders and files).

 

To be able to remove the appdataold share it needs to be empty so delete everything in that share. Then you can go back to User Shares and appdataold. Share empty? should now be yes and you can delete it from within the GUI. Then go to settings and Docker and enable it. If it’s already enable disable it enable it again and set it to the docker.img on appdata

 

Edit: When doing the copying, copy from a user share to a user share: From /mnt/user/appdataold to /mnt/user/appdata

Never! copy from a disk share to a user share, like from /mnt/disk2/appdataold to /mnt/user/appdata

After fixing up your appdata, odds are that your docker.img is messed up (probably due to it filling up due to improper filling out of paths within the container).  Easiest fix would be to delete the image then recreate it and add all of your containers back in through the my* templates

That worked!!

 

Thanks again!
