... ok thanks for this link. I had a few resources in one group and now I am running without a group and it works fast and find.

I am having problems getting live migrations to work under Pacemaker as
well, but I haven't had any time to investigate. I do know that
configuring Pacemaker is a tricky business. There are a number of
different monitoring and timeout parameters that have to be set just
right in order for things like this to work. If the migration takes
longer than the default timeout to complete, it can cause Pacemaker to
think the resource has failed. I don't know if that is what you are
experiencing, but the clues are in the HA logs. Unfortunately the
Pacemaker logs are quite verbose and hideous to try and decipher; that's
where the folks on the linux-ha list may be able to help.
