Oracle Linux 8: System Administration III — Lesson 2: Storage, Filesystems, LVM, and High-Availability Data Services

Technical Scope

• LVM design, snapshots, thin provisioning, and growth planning
• XFS administration, quotas, tuning, and repair
• multipath, iSCSI, device discovery, and persistent naming
• storage failure isolation, recovery tests, and evidence capture

Instructor Demonstration

Demonstrate LVM design, snapshots, thin provisioning, and growth planning within an enterprise Oracle Linux estate standardized through automation, hardened services, storage changes, performance incidents, and controlled recovery, then capture the exact configuration, command, transaction, report, trace, or code evidence that proves the expected result.

Applied Workshop

Implement a controlled workshop covering XFS administration, quotas, tuning, and repair and multipath, iSCSI, device discovery, and persistent naming, then test a failure, exception, or business-control scenario involving storage failure isolation, recovery tests, and evidence capture.

1. Confirm the environment, identities, data, dependencies, controls, and expected result.
2. Complete the product-specific configuration, development, analysis, or business-process task.
3. Capture commands, configuration, output, logs, transactions, reports, or test evidence.
4. Explain the operational, security, performance, data-quality, or business trade-off.

Validation Standard

The Storage, Filesystems, LVM, and High-Availability Data Services result must be reproducible, traceable to approved inputs, and consistent with expected Oracle product or business-process behavior.

• The intended target, scope, and ownership are verified.
• The result is supported by reproducible evidence and expected-value checks.
• Security, performance, reliability, data quality, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance or release.

Failure Analysis

Diagnose issues in LVM design, snapshots, thin provisioning, and growth planning, XFS administration, quotas, tuning, and repair, multipath, iSCSI, device discovery, and persistent naming, or storage failure isolation, recovery tests, and evidence capture without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.

Practical Outcome

Complete a validated implementation or analysis for Storage, Filesystems, LVM, and High-Availability Data Services and defend the result with documented evidence.
