I recently switch from image to directory for dockers binaries, and today I wanted to move this directory to a different disk.

 

- I disabled docker service

- Used the browser file manager to move the binaries folder to a new drive

- Updated the docker directory field with the new path

- Started docker

 

Only to get the following in my syslog:

Should I not be able to do what I am doing?

Nope, you have to wipe it and recreate on the new drive.

Image is easy to move, folder can't be moved as it makes use of filesystem featrues that won't survive a simple copy. 

 

Also it seems the drive you want it on is zfs, folder on zfs drives is known to be problematic and break often/cause server crashes. Switch back to image if you want your Docker system on a zfs drive.

Thanks - I was afraid of that.
