Is this in a two-node cluster?

Yes.

I'm sorry. 
It caused misunderstanding.

It is time when STONITH is carried out in the environment of two nodes by a standby node.

A resource is started without waiting for completion of STONITH from a DC node.
While STONITH is not completed, this problem happens if an active node fell.

I confirmed the same confirmation based on OpenAIS.

No.
It is node A to reboot. 
- Node A is the one that node B is going to shoot.

>

Yes.
A dummy resource is started at the time of DC node B. 
When node B is not DC, it is not started.

Re: When STONITH is not completed, a resource starts.

Hi Andrew,

The log is attached to the first email.

Or do you need other log?

The answer to the first question is no.
Because the reason is because nodes to reboot were different from your recognition.

The answer to the second question is a yes. 
Only a dummy resource starts. 
But I do not confirm it when I set more group resources.
