Hi @dandv ,
I just looked at my disk usage on my Linode-based discourse node and found that the devicemapper sparse data file was using almost my whole disk space allocation. So I am about to embark on the process I gather that you already did: moving my Discourse forum from one Ubuntu 14.04 Linode to another with aufs enabled.
I’ll use the steps you kindly contributed above to provision the new linode. Based on what you wrote in the restoring backups thread, I assume that I should also copy over my app.yml file to the new docker install.
Can you say if there is anything else that you needed to do to completely and seamlessly move your forum from the devicemapper host to the aufs host?
TIA
