Prepare local storage: disks, partitions, file systems and mounting
Prepare a server's local storage: identify disks, partition them, choose and create a file system (ext4, XFS, Btrfs), mount it persistently or on demand, manage swap, monitor capacity, quotas and performance.

Beyond the lessons
Assess, practise, pass the proof
Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.
Assess yourself
14 quizzes
At the end of the lessons: passed at 70%, they confirm the skill.
Practice
8 guided labs
- Mount a filesystem on demand with autofs
- Diagnose a full filesystem and reclaim space
- Create and label an XFS filesystem, then mount it
- Mount a filesystem persistently by UUID in /etc/fstab
- Create GPT partitions on a disk with parted
- Tune a mount for performance with noatime (persistently)
- Add and manage swap space
- Enable XFS user quotas and enforce a limit
Proof
No proof
A practical proof is a challenge, a capstone or a declared lab.
Used by the mission “Put a server into production”, which has its proof.
