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,

Hello,

Thank you for this very fast reply!

Looking at the java sources I found that the problem was with the RA and
not with DMC.
Right, if i fix the RA's XML-Metadata everything works as expected.

I will check out dmctest-0.9.1.dev.x.jar

Thanks,
Steve
