Description
Large cluster designers would like to be able to get as much information about a CephFS file's location as possible. Certainly it should include:
Each object used by the file
The PG of each object
The location of each PG.
Other bonuses might include making it easier to identify the object on-disk (the actual object file, not just the owner), so that they can see if a problem in a CephFS file is caused by a specific disk issue.
