RHEL 8

Configuring Local Storage

Storage is at the heart of every Linux system and something that you will need to know as a Linux administrator. This course will teach you how to use block devices in Linux, preparing them with partitions and creating logical volumes with LVM2.

Administering Linux servers has to involve managing disk and local storage. In this course, RHEL 8: Configuring Local Storage, you’ll learn to list and analyze your local block devices, creating new loopback devices as required. First, you’ll explore the tools used to list block devices. Next, you’ll discover how to add more block devices using losetup, creating loopback devices and partitioning them using parted. Finally, you’ll learn how to create and manage LVM2 logical volumes. When you’re finished with this course, you’ll have the skills and knowledge of Linux storage enabling you to partition an existing disk or create new loopback devices. You also be able to manage ongoing storage in a dynamic manner using LVM2.

Reviews summary

Rhel 8 storage: clear, practical, foundational

According to learners, this course provides a clear and practical foundation for configuring local storage on RHEL 8, particularly excelling in its coverage of LVM2. Many appreciate the well-structured content and the instructor's ability to offer crystal clear explanations, making complex topics accessible. The hands-on labs and helpful demonstrations are frequently cited as essential for solidifying understanding and offering real-world applicability. While largely positive, some intermediate learners indicate it may feel too entry-level if seeking advanced troubleshooting or deeper dives, suggesting it's ideal for those new to RHEL storage or preparing for certification.

Excellent and clear explanations of LVM2 concepts.

"The instructor's explanations of LVM2 were crystal clear, making complex concepts easy to grasp."

"The logical progression of topics from block devices to LVM2 was perfect."

"I particularly appreciated the detailed walkthroughs for creating and managing logical volumes."

Labs and demos are crucial for reinforcing learning.

"The hands-on labs were essential and really helped solidify my understanding of configuring local storage on RHEL 8."

"The practical approach to LVM and partitioning is exactly what I needed. Everything is clearly explained and demonstrated."

"The labs were well-designed and directly applicable. I feel much more confident in my sysadmin tasks now."

Course delivers concepts with clarity and strong practical application.

"This course is incredibly well-structured and highly practical. The instructor's explanations of LVM2 were crystal clear, making complex concepts easy to grasp."

"Excellent course! The content is perfectly aligned with what you need for managing storage in a Linux environment. The instructor breaks down topics like LVM into manageable segments..."

"Very practical and to the point. The instructor does a great job of explaining the 'why' behind the commands, not just the 'how'."

Some lab setups or instructions may require troubleshooting.

"My only minor gripe is that a few lab setups were a bit tricky to replicate without extensive prior knowledge, but the overall value is high."

"Some lab instructions felt a little outdated or didn't quite match the RHEL 8 environment I was using, leading to some frustration."

Ideal for beginners, may lack depth for advanced users.

"The course covers the basics adequately, but I found some parts a bit too rushed, especially the more complex LVM operations. As someone with some prior Linux experience, I was hoping for a deeper dive."

"Good for absolute beginners, maybe less so for intermediate users."

"It teaches the basics, but it felt a little too entry-level for me. I was hoping for more advanced topics or troubleshooting."
