I'm interested in extracting the mappings of a particular device, too. In fact, I've implemented this (along with extracting the mappings in binary format) and have only recently opened a PR: https://github.com/jthornber/thin-provisioning-tools/pull/49. It seems that we've replicated some work here, I'm not sure whether we're supposed to send patches to this list or open PR on github. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
