Personally I feel more save with updates when the whole cluster node is offline, not standby. When you are going to boot anyway, it won't make much of a difference. Also you don't have to remember to put the node back online in the configuration. For your case: After Rebooting the first node, the second one was DC. If you reboot that, the first node becomes DC, but when booting node 2 it still have the old config saying it it the DC. So both nodes have to agree on that. Maybe that's why the cluster is "unclean" for a while. Did it "go away" after some time?
