Local Storage

Partition disks with MBR and GPT. Build the full LVM stack from physical volumes through logical volumes. Extend volumes without data loss. Configure swap and persistent mounts in fstab.

Labs in this module

MBR and GPT Partitioning - Partition a spare disk on RHEL 10. Survey with lsblk, read a disk table with fdisk -l, then carve a sized, typed partition with the interact
Physical Volumes and Volume Groups - Build the bottom two layers of LVM. Stamp a partition into a physical volume with pvcreate and inspect it with pvs and pvdisplay; then pool
Create and Remove Logical Volumes - Carve usable storage out of a volume group with lvcreate: size by capacity with -L 1G or by exact extent count with -l 40 (the classic exam
Extend Volumes Non-Destructively - Grow a logical volume and its filesystem online without unmounting or losing data. Extend the LV by a delta with lvextend -L +512M or fill t
Swap: Partitions and Logical Volumes - Add swap to a RHEL 10 system non-destructively and make it survive reboots. Build a swap area from a partition or a logical volume, then run
fstab by UUID + Emergency Recovery - Mount filesystems persistently by UUID in /etc/fstab and recover a machine a bad line dropped into emergency mode. Read the UUID with blkid
Mission Control: Operation Bedrock - The RHCSA local-storage capstone on a real RHEL 10 machine with two spare disks. Build the full LVM stack, partition to persistent UUID moun
