Ok, I'd found that bit in the docs, but it's good to get confirmation.

Aha!  The black-magic incantation I need to recite under a full moon 
when
the planets are aligned... :-D  Thanks!

Ok, this I can handle.  However, I have one more question.  Since DRBD
already does my unclean-shutdown detection for me, I don't want the
fileserver to force a salvage in the following circumstance:

Server A              Server B
[Running]             [Running]
[Dies]
                       [Takes over /vicepa]
                       [Salvages /vicepa]
[Started]
[Takes over /vicepa]
[Salvages everything] <== This is a duplicate

Is there any file I can delete before starting the bosserver to indicate
that all filesystems it finds are already clean?

Cheers,
