Here's your problem. This means that fs_drbd is not allowed to
run on that node.
> location loc-2 drbd_disk -inf: dnsvm1
You should drop this one too. Try sth like this instead of the
above two:
location prefer_dnsvm2 fs_drbd 100: dnsvm2

You should tune the timeouts.

I guess that you need to reference ms_drbd and then specify the
role as well.
