Thanks for the quick reply.  Not purposefully.  I've always used the
logical LVM names for setup.  I pointed out the difference in device
mapper ids as:

- it was something different between the previous succesful setup and
  now
- I saw a thread from 'Orakel von Delphi' with similar symptoms.

I guess DM can number the devices however it likes between boots, but
will btier care as long as btier_setup only ever refers to the logical
volume names?

Thanks,

Chris
