riak-admin diag output

Hi my riak admin diag shows output as below(3-node cluster)

I'm assuming long numbers are vnodes. Strange thing is:

5708990770823839524233143877797980545530986496 exist twice for the same node

19981467697883438334816003572292931909358452736 once on the list

How do I interpret this?

How can I list all vnodes and nodes that they are exist on, riak-admin
vnode-status

shows only primary locations, what about copies?
