Unfortunately, there's no general purpose way - the faq explains why (I just fixed the wiki so it's there again :) http://bcache.evilpiepirate.org/FAQ/ However, Gabriel de Perthuis has a tool to do in place conversion - I can't remember if it was limited to lvm devices or not - Gabriel, what was the link to that again?
