Abstract
Locating a file object in a storage system includes determining at least one characteristic of the file object, obtaining a subset of nodes in the storage system by applying the at least one characteristic to criteria for storing file objects at particular ones of the nodes in the storage system, and examining the subset of nodes to determine if any contain the file object. A metadata location server may be used to obtain the subset of nodes. The criteria may include at least one policy relating to placement of objects corresponding to files at the time the files are created. The policies may relate to owners of the files. The characteristic information may include the owner of a target file corresponding to the file object, the date that the target file was created, a business organization associated with the target file, and/or the size of the target file.
