Introduction
This article contains a glossary of terms related to FedFS.
Glossary
Domain Root Directory
A domain root directory is the top-level directory of a FedFS domain's namespace.
FedFS Domain
A FedFS domain is a file name space that can cross multiple shares on multiple file servers.
Globally Useful Name
The Globally Useful Name is a pathname in the FedFS domain namespace which is the same no matter which client is used to access the file.
Junction
A junction is a link between two shared file systems. The two shared file systems may not reside on the same server. There may be more than one replica of the linked-to shared file system, stored on several different file servers. Junctions store a list of locations.
Junction Resolution
The process where a file server converts the contents of a junction to a list of locations that can be used during a referral.
Location
Each replica of the linked-to file system is called a fileset location, or location, for short. A location is represented as an export path paired with a server name or IP address.
Namespace Database
The Namespace Database, also known as the NSDB, is a central repository of FedFS domain namespace information that is shared among all file servers in a FedFS domain.
Referral
A referral event occurs when a file server reports to a client that the object (typically a directory) it is trying to access has moved. The client responds by requesting a list of locations where it can find the object.
