LVM Lab

Objective: Create, format, and extend logical volumes using LVM.

1. Locate the Device to be Used for LVM
```
lsblk
```
Note: This lab uses /dev/sdb, which shows a size of 40GB.
2. Prepare the Device for LVM
```
sudo parted /dev/sdb
```
Note: Review available commands and arguments within parted.

Inside parted:
```
mklabel gpt
mkpart lvm_lab1 1MB 5GB
set 1 lvm on
```
- lvm_lab1 = partition name
- 1MB 5GB = start and end positions
- set 1 lvm on enables the LVM flag on partition 1
3. Create Two Additional 5GB Partitions

Create two additional 5GB partitions using the same method as above.
4. Exit parted
```
quit
```
5. Verify the New Partitions
```
lsblk
```
Expected Partitions:
- /dev/sdb1
- /dev/sdb2
- /dev/sdb3
6. Create a Physical Volume
```
sudo pvcreate /dev/sdb1
sudo pvs
```
Note: /dev/sdb1 should now be listed as a Physical Volume.
7. Create a Volume Group
```
sudo vgcreate lab_vg /dev/sdb1
sudo pvs
sudo vgs
```
Note: Verify that lab_vg exists and includes the Physical Volume.
8. Create a Logical Volume
```
sudo lvcreate -L 3G -n lab_lv lab_vg
sudo lvs
```
Note: The logical volume has been created but is not yet formatted or mounted.
