Hi David,
Thank you for comments.

However, the resource moves by a calculation of the next state transition.
By a calculation of the first trouble, can it not travel the resource?
In addition, the resource moves when the resource deletes next colocation.
colocation rsc_colocation-master-3 INFINITY: vip-rep msPostgresql:Master
There is the problem with handling of colocation of some Pacemaker?
Best Regards,
Hideo Yamauchi.
