Hi, is it possible to clone only a slice and not the whole drive? I have a 3.2-R System with vinum-mirrored disks. Both drives are configured the same way. The only problem is that vinum doesn't mirror root slices. So I would like to clone only the root slice from time to time to keep the second drive up-to-date. Should I do this with dd or can I do a "cp /dev/da0a /dev/da1a" Both partitions have the same size and the same position on both drives.
