Ceph MDS (Metadata Server)

Ceph MDS (Metadata Server) manages the organization and tracking of files within a Ceph storage system. Think of it as a librarian that keeps an index of where each file and folder is stored across multiple disks and servers. It handles directory structures, filenames, permissions, and metadata, allowing clients to quickly locate and access their data. By efficiently managing metadata, Ceph MDS ensures smooth, scalable, and reliable file access in large, distributed storage environments, much like a well-organized library system that quickly guides users to the right books.
