Abstract
Example apparatus and methods concern metadata peering that allows a file system to address a file in a local namespace while actually accessing the file using an address used by a shared secondary storage. This allows the file system to operate unmodified and more efficiently in a native mode that addresses files in the shared secondary storage using addresses local to a computer running the file system. An example method accesses an inode associated with a file that is stored in a shared secondary storage. The method accesses a local namespace identifier used by the file system to access the file and accesses a reference used by the shared secondary storage to access the file. The reference is not associated with the local namespace. The method stores an opaque value in the inode. The opaque value facilitates accessing the file in the shared secondary storage using the local namespace.
