[Pacemaker] Being fenced node is killed again and again even the connection is recovered!

Hi Folks,

I setup a three nodes cluster with SBD STONITH configured.
After I manually isolate one node by running "ifconfig eth1 down" on the
node. The node is fenced as expected.
But after reboot, even the network is recovered, the node is killed again
once I start openais&pacemaker.
I saw the state of the node become from OFFLINE to ONLINE from `crm_mon -n`
before being killed. And I saw SBD slot from reset->clear->reset.

I attached the syslog and corosync log.
And my CIB configuration is very simple.

Could you help me check what's the problem? In my mind, it's not expected
behaviour.
