It should, assuming that the KXXfoo entries exist for the cluster
services in the right order, and that they all shut down properly. Of
course, I find this not always is the case. So for that reason, I like
to stop things manually, when I have the luxury.
As for starting, it depends. If it's a machine I have ready access to, I
generally like to start things manually. Mainly because of how heavily I
use DRBD and it's tendency to have issues on startup. Not frequent, but
frequent enough. If you do automatically start everything, pay close
attention to the start order and do plenty of testing.
