Hi,
when trying to migrate from plain LV disk backend to DRBD using the
following the following command, the conversion fails if the LV is still
marked as online. Also the instance is unbootable afterwards.

I renamed the LVs back to what ganeti expected them to be named, so the
instance gecomes bootable again.
I found out that the kernel knew about one LV having a partition:

IMHO it should be easy to catch for "gnt-instance modify" if one of the
volumes is still marked as online and then should just stop before
renaming the LV and throw an error.
Best regards,
Martin
