Not yet. But currently you can 'dog cluster info -s' to see the global policy
scheme x:y (that you 'dog cluster format -c x:y').

With erasure coding, 'copies' will have another meaning that the number of total
data + parity objects. In your case, it is 2+1=3. But as you said, this is
confusing, I think of adding a extra field to indicate redundancy scheme per vid.

Well, for about issue, I can't reproduce it. Could you give me more envronment
information such as 32 or 64 bits of your OS? what is your distro?

Thanks
