doh.
please try again with drbd 8.0.5.
thanks.

changelog entry:
  * Changed the maximal length of device names from 32 characters to
   128 characters. (udev based disk names might be very long nowadays)

likely your /dev/mapper/xendomains-swap_license
managed to overflow some internal buffer.
I hope we have proper limit checks in place there, now...
if not, that will be a reason for 8.0.6 pretty soon.
