Mission Control: Operation Bedrock

lvcreate - a hands-on Linux lab on a real virtual machine.

The RHCSA local-storage capstone on a real RHEL 10 machine with two spare disks. Build the full LVM stack, partition to persistent UUID mount, graded on live end-state. Mission mode.

You have finished the Local Storage module, the heaviest domain on the exam. Now you lay the bedrock on a real RHEL 10 machine with two blank disks: a partition, a physical volume, a volume group, a logical volume with a filesystem, a swap area, and a persistent mount. This is the full storage stack, built the way the exam asks and graded on the live result.

Six objectives, one real machine with spare disks vdb (5 GiB) and vdc (2 GiB). Everything you build must survive a reboot, because the graders reboot before they score.

This is mission mode. No commands are shown. You read the objective, recall the tool, and build the layer. You will need root, so reach for sudo. Progress checks itself against the live storage stack.

One quick rep before you start. Before you carve anything, you look at the disks you have to work with. List the block devices and their sizes.

prompt: [root@servera ~]# answer: lsblk output: NAME SIZE TYPE MOUNTPOINTS vda 15G disk vdb 5G disk vdc 2G disk hint: lsblk lists every block device as a tree. Your two blank spares are vdb and vdc, with no partitions yet.

There are your raw materials: vdb and vdc, empty and waiting. The mission builds the storage stack on them, one layer at a time.

Boot the machine below and take the console. Read ~/BEDROCK.txt for the checklist. Six objectives: partition vdb, pool it into a volume group named vgdata, carve and mount an XFS logical volume at /apps, grow it, add swap on vdc, and make /apps mount by UUID. Work as root, and make it all persistent.

Practice Mission Control: Operation Bedrock in a real Linux terminal at The Linux Camp. Progress is verified automatically as you type commands on the machine.
