LAB-DISK-02 - Mounting and Partitions
Understand mounting and partition concepts in a safer practice-oriented way before making live changes to real storage devices.
Mounting and Partitions
Understand mounting and partition concepts in a safer practice-oriented way before making live changes to real storage devices.
- Understand mounting and partition concepts in a safer practice-oriented way before making live changes to real storage devices.
- Repeat the workflow without copy-paste or step-by-step prompting.
- Never test partitioning, formatting, or mount changes against data you cannot afford to lose.
Part A: The Field Guide
Mounting is the act of making a filesystem accessible at a chosen location in the directory tree.
This is different from partitioning and different from formatting.
That difference matters because the risks are different:
- inspection is low risk
- mounting changes accessibility
- formatting or repartitioning can destroy existing data
Safety Rule
If you are not on a disposable training device or VM, keep this lab observational. Understanding the layout is already valuable and much safer than live repartitioning.
Part B: The Drill Deck
Terminal required: focus on inspection first.
G Guided Step by step - type exactly this and compare the result >
Exercise G1: Inspect the storage layout
- Run
lsblk - Run
mount | head - Run
df -h - Compare the device names, mount points, and filesystem usage views
Exercise G2: Find one mount point
- Pick one mounted filesystem from
df -h - Find the same mount point in
mount - Explain how those two commands are describing related parts of the same system state
Exercise G3: Read fstab carefully
- Run
cat /etc/fstab - Notice that this file describes mount behavior expected at boot
- Explain why a mistake here deserves caution even if the syntax looks like simple text
S Solo Task described, hints available - figure it out >
Exercise S1: Concept separation
In your own words, explain the difference between:
- partitioning a disk
- formatting a filesystem
- mounting a filesystem
Exercise S2: Safe planning mindset
Describe the checks you would do before mounting a new external drive on a real machine.
M Mission Real scenario - no hints, combine multiple skills >
Mission M1: Write a safe storage checklist
Write a short checklist for any real storage change:
- identify the exact device
- verify whether data already exists
- confirm whether the action is inspection, mount, format, or partition change
- back up if needed
- verify the result afterward
If that checklist feels natural, the storage teaching is landing correctly.
