August 31, 20214 yr Hi forum, yesterday my cachedrives became full and now my docker service doesn't work/falils to start. Perhaps you guys have some insight. I believe this started when I followed this guide to shrink one of my vdisks (which is on the cache drive.... I know). https://www.youtube.com/watch?v=wJBrEoq8mHo. Perhaps I screwed something up... So what are the next steps for me to unscrew this situation? Can someone give me some advices? I would like to be able to run the docker services again and also move the vdisk somewhere else for now.

August 31, 20214 yr Community Expert Disable Docker in Settings and change it back to 20G, which is plenty. That is its current size and you haven't been using much of that. It looks like you tried to change it to 35G but you definitely don't need to make it larger than 20G. Leave Docker disabled until you get some room on cache. Your user shares Use Cache settings look mostly OK, though isos is cache-no and has some files on cache. And appdata has overflowed to the array. Most of your user shares have no files on cache so I suspect it is appdata taking up most of that space. Probably you have some container downloading into it. Go to User Shares, click the Compute All button, wait for the result. If it doesn't show the results after several minutes, refresh the page. Then post a screenshot.

"Leave Docker disabled until you get some room on cache.", how do I do that? The drives (SSD:s) are in the server (I could easily disconnect them and transfer the data via a HDD-reader) but is there an easier way? Edited August 31, 20214 yr by boniac

If you don't enable it again then it is disabled.
August 31, 20214 yr Community Expert As expected appdata is the biggest user of cache, though domains is also using quite a bit. Any idea why your appdata share is 126GB total? I run 16 dockers, including plex, which is notorious for using a lot of appdata, and my total appdata is less than 16GB. Which dockers do you run?
August 31, 20214 yr Community Expert And domains is using nearly 100GB. A VM can access Unraid storage so it isn't necessary to create a vdisk for everything they need to have access to. What VMs do you have?

Just one Windows 10 vm with Origin installed for The Sims 4 and some other games. 44 minutes ago, trurl said: If you don't enable it again then it is disabled.

August 31, 20214 yr Community Expert What do you get from the command line with this? du -h -d 1 /mnt/user/appdata

September 1, 20214 yr Author Shall I try to move everything from the cache drive to a safe storage place, accordingly to this guide? https://wiki.unraid.net/Replace_A_Cache_Drive ? Just to confirm, the shares that should be backed up is: appdata domains isos system windowsdisk (my VM share)

Now I have enough free disk space but docker still gives me "Docker Service failed to start.". Any clue?
