[DRBD-user] State change failed messages creating a DRBD 9 cluster

Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I am running the following on three RHEL 7.2 Server VMs:

When I added the second and third nodes to the cluster I got a number of 
messages like:
drbd .drbdctrl: State change failed: Peer may not become primary while 
device is opened read-only

Running dmesg on the node from which I issued all the drbdmanage commands 
I see some messages like:
Failed: peer( Secondary -> Primary )
Aborting remote state change x

I also see a couple of messages like:
Rejecting concurrent remote state change y because of state change z

Running "drbdmanage list-nodes" shows all the nodes as ok so is it safe to 
ignore these messages?
