[Pacemaker] how to realize group with colocation?

[李森]

I failed my apache myself for testing.

my problem is if the first resource in the group runs ok and the second
resource in the group is failed, the whole group will not move to another
host.

I want to realise that if any of the resource in a group is failed, then the
whole group is failed.and the whole group will move to another host.
