What is a distributed file system?
A distributed file system is a physically distributed implementation of the classical time-sharing model of the traditional file system, allowing users to manipulate, organize, and share data seamlessly, regardless of its actual location on the network.
A distributed file system resides on different machines and/or sites, and offers a unified, logical view of data scattered across machines/sites, whether local or remote.
Metadata in object storage systems can be augmented with custom attributes to handle additional file-related information. Doing so with a traditional storage system would require a custom application and database to manage the metadata (these are known as “extended attributes”).
