The bug happens in cases like below:
1. some nodes of your cluster crashes
2. then, the entire cluster crashes (stops without "dog cluster shutdown")

In such a case, previous sheepdog uses wrong vnode information after
rebooting. So different data placement maps are used in single
cluster.

Thanks,
Hitoshi
