Obviously the case I have included in the first mail shows up the problem immediately, but in fact it is reasonably hard to trigger and I spent quite a while getting to the state of being able to trigger the uninitialized pages on demand. While Pitrtools it is a wrapper, the use of "--exclude=backup_label" is incorrect and needs to be removed. regards Mark
