> During the investigation of TS-949 it came to light that even a consistent 
> hashing solution fails to maintain access for all objects in the cache when a 
> new volume is added.  This is because a new volume will necessarily assume 
> ownership for some portion of the object/hash space.  As a side effect of 
> this ownership change, new searches for previously cached objects may return 
> the new owner instead of the previous owner (which retained the cached copy). 
>  According to the volume itself (and thus several aggregate statistics like 
> cache space usage), the objects are still valid and will remain as effective 
> dead weight until evicted during the normal cache operation.
> See comments on TS-949 for initial discussion of possible solutions.
