Oh, just to clarify, dm-cache itself can be used to cache a pv, sitting between the raw device and lvm; it's just that lvm will not support setting that up, you would have to do that directly with dmsetup... I posted an inquiry on that topic back in December: https://www.redhat.com/archives/dm-devel/2013-December/msg00038.html It was pretty much confirmed that it would work, it would just be a rather manual process. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
