Before this lab
What success looks like
- Identify available memory separately from free storage.
- Identify the main storage volume or mounted filesystem.
- Finish without opening repair or format tools.
Safety notes
- Do not open format, partition, or repair tools in this lab.
- Stay in read-only inspection commands and views.
Goal
Separate memory pressure from storage capacity before you act on either one.
Safe sequence
- inspect memory
- inspect the main storage volumes
- identify free space
- stop once the map is clear

Look for the difference between memory numbers and drive free-space numbers. They answer different questions.
free -h lsblk df -h
free -h tells you about memory. lsblk and df -h help you understand storage and mounted space.
Move on when
- you can identify available memory
- you can identify free storage space
- you can explain why those are not the same resource
