If you just want to make one disk (b) available in order to swap it when the master disk fails (w), then labels are fine. I'm not sure what your main purpose of cloning the disks was. Two options: a) keep two disks in sync, so you can use your backup disk when the working disk fails and needs to be extracted b) make a clone of your working disk so it can be placed into another system > So the only reason to use glabel, in my case, is to boot from the clone > on another system without worrying about the actual disk label.

Labels work independent from the different settings you might find in different computers, such as different device names (due to different position on the controller). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
