Lecture 12 - Implementations of file systems, distributed file systems #

Scope of the lecture #

• Implementations of file systems
  • Linux file systems: ext2, ext3, ext4, proc, swap, ZFS
  • MSWwin - FAT12/16/32, exFAT, NTFS
  • Disk management: partitioning, formatting, booting (BIOS/MBR, UEFI/GPT)
• Distributed File Systems - optional content.
  • Basic concepts: distributed system, distributed file system (DFS), client, server, service, transparency.
  • DFS structure
  • Naming structures: Location transparency, Location independence
  • 3 basic naming schemes
  • Remote file access: remote-service and caching (disk/main memory). Consistency. Cache update policy.
  • Stateful vs stateless file services: pros and cons
  • File replication. Data deduplication. Areas of application.
  • Network File System (NFS)
