Yes. This works nicely with the new version. One remark I have is that
it is uncomfortable to work with if you have other (less important)
reasons to move the master: the left over "priority space" to work with
is rather small. You have to use values totalling less than 90 or you
will overrule the RA. If you have multiple considerations (multiple
network connections for example), you run out of space quickly.

It only appeared when drbd was syncing and it seems to have disappeared
after upgrading drbd (from 8.3.0 to 8.3.2). It was a line that gave
information about the sync progress.

It is in my experience.

Thanks for the feedback.
