[Pacemaker] It affects it that the update of the attribute by attrd is late, and a resource starts with a standby node.

Sorry....

For pingd, we address 2 of the next.

 * 192.168.4.2
 * 192.168.4.3

When one address cannot communicate, this problem occurs.
When cluster can communicate with both addresses, the resource starts in a srv01 node definitely.
