What file systems are suitable for sharing a Block Volume among multiple compute instances for read/write without data loss?

• A. NTFS and FAT32
• B. Serial File Systems like NFS
• C. Parallel and Distributed File Systems
• D. Local File Systems only

Answer: (C)

The selection of parallel and distributed file systems as suitable for sharing a Block Volume among multiple compute instances for read/write operations without data loss is grounded in their architecture and functionality. These types of file systems are specifically designed to manage concurrent access smoothly and provide high availability and fault tolerance. Parallel and distributed file systems, such as Lustre or GlusterFS, allow multiple nodes to read from and write to the data simultaneously. This architecture is essential in high-performance computing environments where data consistency and integrity are crucial, especially when multiple compute instances are accessing the same data set. Their ability to handle high throughput and distribute data across multiple storage resources ensures that performance does not degrade as demand increases. In contrast, local file systems typically restrict access to a single compute instance, making them unsuitable for this use case, as they do not support multi-user access. Serial file systems, such as NFS, can support multiple readers, but they may encounter issues such as locking and data integrity when multiple instances attempt simultaneous writes. Therefore, parallel and distributed file systems stand out as the most effective solution for shared data access among multiple compute instances, ensuring data is not lost and maintaining reliable performance.
