Intro to File Systems

What is a File System?

• Organization of data on storage devices (HDD, SSD, etc.).
• A system for managing how data is stored and retrieved.
• Hierarchical structure: Directories and files.

Basic Concepts

File

Directory

Path

Metadata (e.g., size, type, permissions).

Filesystem types: NTFS, ext4, HFS+, FAT, etc.

How Files are Stored on Disk

• Whether it's a traditional hard drive (HDD) or a solid-state drive (SSD), blocks are the smallest unit of data storage. When you save a file, the operating system breaks it down into smaller pieces called blocks (also known as sectors in some contexts). These blocks are then written to storage.

• Writing is fast in SSDs because there’s no mechanical movement involved, unlike HDDs. The SSD can access any part of the drive instantly.

• In Unix-like operating systems (such as Linux or macOS), files have something called an inode (index node). An inode contains information about a file, like: size, permissions, creation/modification time, location on disk. It is the "ID card" of a file, which tells the system all the important details about it, except the actual data (the content of the file itself).

File System Journaling

Changes are ‘COMMITTED’

New file and Old file still exist

• File Systems have tricks for ensuring data consistency, such as Journaling.

• Journaling logs file system changes before they happen, making it easier to recover from crashes and power failures.

• Benefits of Journaling
• Atomic Transactions (no halfsies)
• Crash Recovery
• Consistency of Metadata and Data

How Files are Stored on Disk

• File Path: The path is the location of the file within the file system. It’s like the address of the file on your computer. A file path could be something like /home/user/documents/file.txt or C:\Users\user\Documents\file.txt.

• Directory: Directories are like folders that organize files. They can contain both files and other directories (subdirectories), helping to create a structured, hierarchical organization of data.

• Command Line/Shell/Console/CLI/PowerShell/Bash/Prompt: You can execute commands on a computer without Mouse/Window controls. Some computers CAN ONLY BE ACCESSED this way!

Distributed File Systems

Do you think a Distributed File System still requires a path?

How does it work for a very large file that cannot be stored on one disk?

Lab b: create and edit a file in cloud storage (using cloud shell)

22

Cloud shell

• Your cloud shell is cockpit access to the wide ‘cosmos’ of the public cloud

Due:complete lab and submit evidence

Your Current Device

Can you tell?

What kind of hardware is the device you are on using?

• HDD
• SSD
• Something else
