Ever had your Linux system refuse to boot because of a mysterious disk error? Or maybe you've stared at `df -h` wondering why it's lying to you about free space? Storage in Linux isn't just about plugging in a drive; it's a critical, often misunderstood, dance.
Watch to learn more!
In this video, we explore Storage and Disks: mounts, df/du, partitions, fstab | Linux Made Practical (Part 5). Perfect for developers and tech enthusiasts who want to understand the fundamentals.
🎯 KEY TAKEAWAYS:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Always use UUIDs in `/etc/fstab` for stability, found with `blkid`.
• Backup `/etc/fstab` before making any changes (`cp /etc/fstab /etc/fstab.bak`).
• Test `fstab` changes with `sudo mount -a` before rebooting to catch errors early.
• Understand the difference between `df` (filesystem free space) and `du` (directory used space) for accurate troubleshooting.
