Managing File Systems and Storage in RHEL 9

Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

To start, you will earn how to manage storage devices and partitions in RHEL 9 using essential Linux commands like lsblk, fdisk, parted, and mkfs. In this challenge, you’ll identify available storage devices, create partitions using both fdisk and parted, and format them with the appropriate file system. By mastering these disk management techniques, you’ll be able to efficiently allocate and manage storage in enterprise Linux environments, ensuring optimal performance and reliability.

In this challenge, you will learn how to manually mount file systems and configure persistent storage management. In this challenge, you’ll practice mounting partitions, verifying access, and automating storage mounting using /etc/fstab. You’ll also explore mounting using UUID and LABEL to ensure reliable disk identification.

Finally, you will learn how to manage storage using Logical Volume Manager (LVM). You will start by creating physical volumes using pvcreate, then combine them into volume groups with vgcreate. After that, you will create logical volumes to store data. You will also learn how to expand storage when needed by adding more space to a volume group using vgextend and increasing the size of a logical volume with lvextend. Finally, you will adjust the file system using resize2fs to make sure the extra space is usable.

Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
