Oracle Linux 8: System Administration I — Lesson 2: Partitions, LVM, Filesystems, Swap, Mounts, and Storage Operations

Learning Objectives

• Explain the architecture, workflow, or business purpose behind block devices, partitions, UUIDs, and persistent device naming.
• Apply physical volumes, volume groups, logical volumes, and resizing and XFS and ext4 creation, mounting, fstab, quotas, and capacity in a controlled scenario.
• Validate outcomes and troubleshoot risks involving swap, permissions, recovery checks, storage incidents, and evidence.

Detailed Topics

• block devices, partitions, UUIDs, and persistent device naming
• physical volumes, volume groups, logical volumes, and resizing
• XFS and ext4 creation, mounting, fstab, quotas, and capacity
• swap, permissions, recovery checks, storage incidents, and evidence

Instructor Demonstration

Demonstrate block devices, partitions, UUIDs, and persistent device naming within a new Oracle Linux application host prepared, secured, validated, and handed to production support, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 2.

Hands-On Exercise

Implement a controlled exercise covering physical volumes, volume groups, logical volumes, and resizing and XFS and ext4 creation, mounting, fstab, quotas, and capacity, then introduce and resolve an exception involving swap, permissions, recovery checks, storage incidents, and evidence while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across block devices, partitions, UUIDs, and persistent device naming, physical volumes, volume groups, logical volumes, and resizing, XFS and ext4 creation, mounting, fstab, quotas, and capacity, swap, permissions, recovery checks, storage incidents, and evidence without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Partitions, LVM, Filesystems, Swap, Mounts, and Storage Operations in a realistic Oracle Linux 8: System Administration I scenario and validate the result with documented evidence.
