I've just pushed an interface change for multisnap. >From now on the 'new-thin' message to the pool target takes just one argument, the id of the new device. The size field has been dropped, instead the new device has a zero size. When a multisnap target is loaded it implicitly resizes the thin device based on the size of the target. Truncation will lose data that is off the end of the new device immediately. - Joe https://github.com/jthornber/linux-2.6/tree/multisnap -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
