Re: [Linux-cluster] fencing loop in a 2-node partitioned cluster



And these are the logs I see on the wo nodes:
the first node:

the OPERATIONAL state.

The result is that both nodes went in power off state and I manually
needed to power on them.

As I also have debug enabled for qdisk, these are the logs for it:
