August 10, 20223 yr Community Expert Filesystem Size Used Avail Use% Mounted on /dev/loop3 50G 49G 1.1G 98% /var/lib/docker Docker image is full, this is usually the result of a misconfigured container.
August 10, 20223 yr Author How can I verify? And if so how do I fix? Still very new to this so as much detail you can provide would be appreciated.
August 10, 20223 yr Community Expert The linked thread has some good explanations of what causes this so be sure to read. Then https://wiki.unraid.net/Manual/Docker_Management#Re-Create_the_Docker_image_file You had 50G, but 20G is probably more than enough and making it larger won't fix problem of filling it, it will only make it take longer to fill. https://wiki.unraid.net/Manual/Docker_Management#Re-Installing_Docker_Applications Reinstall one at a time and examine each one with consideration of the discussion in that other thread to see if you can figure out what might be happening. On the Dashboard page, you can see the percentage of docker.img used in the Memory section. It should only grow, and not a lot, when you install another docker. If it is growing when you aren't installing anything then some container is writing into it instead of to mapped host storage. After you get some of your containers reinstalled, click the Container Size button at bottom of Docker page and post a screenshot.
August 10, 20223 yr Community Expert Related, but not the cause of your problem. appdata share has files on the array. Ideally, all of appdata, domains, system shares should be on fast SSD pool (cache), and set to stay there (cache:prefer or cache:only). If these are on the array, docker/VM performance will be impacted by slower parity array, and array disks can't spin down since these files are always open. You should set appdata to cache:prefer so mover can move it to cache. And since nothing can move open files, you will have to disable Docker and VM Manager in Settings so these can be moved.
