Disks and file systems
Manage storage, mounts and space.
📖 Key ideas
- df -h shows disk usage; du -sh folder shows folder size.
- lsblk lists disks and partitions.
- File systems: ext4, xfs, btrfs.
- mount attaches file systems; /etc/fstab mounts at boot.
- LVM allows flexible resizing of volumes.
💡 Real-life example: Mounting is plugging a new cupboard into the house so its shelves appear in a room.
