So in the later version it works, right?

allow-migrate is already available in dmctest-0.9.1.dev.7.jar in
http://oss.linbit.com/drbd-mc/
There are also migrate_from, migrate_to timeouts that I've already
implemented and soon will be available as dmctest-0.9.1.dev.8.jar

In the old RA, there's

<shortdesc lang="en">Shutdown escalation timeout</shortdesc>
<content type="boolean" default="" />

In the github version it's been already fixed to a string type. So if you
install the new version on all nodes, restart the DRBD:MC it should be
fixed.

Thanks,
Rasto
