To expand on this a little: a pool does not exist in a single
location. It's sharded into placement groups (PGs), which are then
distributed across the OSDs -- but they can and do move in response to
changing cluster conditions. :)

If you mean that you're trying to mount a rados pool in linux, it
doesn't work like that. RADOS pools are closer to S3 buckets than to a
LUN or a filesystem volume...
