For posterity... Assuming Docker is running, the docker.img vdisk mount point can be found by issuing the following command from the command line. mount |grep docker.img Which (on my system) shows: /mnt/pool-a/docker/docker.img on /var/lib/docker type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) /mnt/pool-a/docker/docker.img on /var/lib/docker/btrfs type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) Once the mount point is found, take a look at the contents: root@beast:/mnt/disk1# ls -l /var/lib/docker total 16 drwx--x--- 1 root root 20 Feb 6 12:32 btrfs/ drwx--x--x 1 root root 152 Feb 6 12:30 buildkit/ drwx--x--x 1 root root 12 Feb 6 12:30 containerd/ drwx--x--- 1 root root 2816 Feb 13 18:30 containers/ -rw------- 1 root root 36 Feb 6 12:30 engine-id drwx------ 1 root root 10 Feb 6 12:30 image/ drwxr-x--- 1 root root 10 Feb 6 12:30 network/ drwx------ 1 root root 20 Feb 6 12:30 plugins/ drwx------ 1 root root 0 Feb 13 18:27 runtimes/ drwx------ 1 root root 0 Feb 6 12:30 swarm/ drwx------ 1 root root 44 Feb 13 18:27 tmp/ drwxr-xr-x 1 root root 12 Feb 6 12:40 unraid/ -rw-r--r-- 1 root root 154 Feb 13 16:53 unraid-autostart -rw-r--r-- 1 root root 5366 Feb 13 17:52 unraid-update-status.json drwx-----x 1 root root 184 Feb 13 18:27 volumes/ The directories and files listed can be safely removed from the previous path. On my server, this was everything under /mnt/pool-a/docker EXCEPT for docker.img. Bottom line... I was unaware that migrating from a directory based Docker data-root to a vdisk Docker data-root would leave behind so many unneeded files and directories.

Thank you very much for the quick responses! Safe to assume I can recursively delete the /mnt/pool-a/docker/image/ directory as well? I'm assuming everything under this directory is now stored in the vdisk. Again, just looking for a sanity check.

I started out with my Docker data-root set to "directory", then installed and removed a few containers while testing out Docker support within unraid. I have since switched the Docker data-root to a vdisk and recreated all of my containers. So far, the containers and container updates run fine. Can I safely delete the entire /mnt/pool-a/docker/btrfs directory now that all of my images are being stored in the vdisk? From what I've gathered this sounds correct, but I haven't seen it worded as such. Just looking for a sanity check before I nuke the /mnt/pool-a/docker/btrfs directory.
