A clustered file system is a type of computer system that allows two or more computers to share information stored on a single file or group of files. This is helpful when you have lots of files to store or access, as it allows you to use multiple computers to store and access your data all at once. In a clustered file system, each computer stores a copy of the files, and the computers all talk to each other so they can stay synchronized. That way, you can access the files from any of the computers, and any changes you make will be reflected across all the computers.
