Hi Folks,

I have a question on pacemaker split brain. Once a cluster is partationed
due to the network problem. If my understanding on the code is correct, two
subcluster all have their private DC regardless who holds the quorum.
So how the quorum winner subcluster take control of the whole cluster and
fence the other partation? I didn't see the election algorithm introduce the
concept of quorum.

Could you answer me?

Thanks
