File System Fundamentals
File System Role
A file system organizes data on storage
devices.
It manages how data is stored and
retrieved.
Key Components
• Metadata
• Inodes
• Directories
• Data blocks
Operations
File system operations include creating
files.
Reading, writing, and deleting files.

Advanced File System Technologies
ZFS (Zettabyte File System)
• Pooled storage model
• Copy-on-write
• Data integrityfeatures
Btrfs (B-tree file system)
• Copy-on-write
• Snapshots and subvolumes
• Online defragmentation
