Well... On the one hand, I'm trying to understand why one would break a cluster in to multiple name spaces. (Obviously this gets back to managing very large clusters.)
On the other. Why would someone want to have a copy of a file in two different name spaces? I'm making an assumption that when we have 3x replication that the replicas don't cross name space boundaries. (Is this correct?) My take is that one would copy a file to a second name space because they want a physical copy in both name spaces for redundancy in case a name space goes down. They would do this only for mission critical files, or if the data is being shared by two different groups who want their own copy of the data and they work solely within a single name space. The reason I am asking is that I'm trying to see how people view and use namespaces. Does that make sense?
