This should have been “undo your fix”. @rimelek thank you for pointing it out.
Your “fix” is to revert to the fallback storage driver, just because you have everything working with it. If “whatever works” is good enough for you, then stick with it.
My suggestion was to properly migrate to the superior overlay2 storage driver and benefit from its stability, efficiency and its higher performance.
There must be a reason overlay2 suddenly became available as storage driver.
Now the docker is installed on lxc container, but i thinking to move to a vm with ubuntu server or debian.
What is the best way to move the container to another host?
