Design a distributed file system.

Focus on the key components of a distributed file system, including data storage, redundancy, and access protocols. Discuss how you would ensure data consistency and availability across multiple nodes, considering factors like partition tolerance and fault tolerance. Be prepared to explain your choices for data replication strategies and how you would handle data synchronization. Additionally, consider the scalability of your design and how it would accommodate increasing amounts of data and user requests. Finally, think about security measures to protect data integrity and user access.
