hope so :)

that would probably help in this case.

yes, we could force a demote to Secondary, and fail all further IO,
if any.  it is probably slightly more involved than it sounds, however,
since normally a secondary may be unconfigured just so, and now we'd
have a secondary with open references to it, so it cannot go away yet.

No, I don't see us implementing it, at least not for this reason.
it does not help at all: the failing Filesystem-RA will cause
Heartbeat to reboot the box even before telling DRBD anything about it...
