I’ve just done a `git pull` on the /var/discourse directory of my host, and am now getting warnings about using devicemapper. I followed the basic install instructions for digital ocean when I set it up last year, and haven’t messed with any docker settings.

What’s the best way to proceed? Should I be trying to change the storage driver, or starting up a new droplet and restoring a backup?
