This is true for the PV in vg_system. This PV was created during installation and I didn't get debian installer to work with multipath (install disk-detect/multipath/enable=true didn't work), so I created it directly on a scsi device. I'm guessing you made this assumption based on the "Found duplicate PV" messages...?

The other PV in vg_services was, if I recall correctly, created on the multipath device-mapper device.

Ah, I understand now.
So how are we going to precede here?

If you're going to tell me, that you can't push this to stable, I'll put a working package on our internal mirror. I opened this bugreport because I feel like this should be fixed officially, so others don't run into the same issues.
It'd already be nice if the "[fd43c41] Drop udev rule to invoke multipath per path." Fix was pushed to stable, as it seems to resolve the boot issue. What are the rules for code in /debian, since there is no 'upstream' of this?
