Check if LVM can access and manage system disks

sudo lvmdiskscan

List physical volume(s)

sudo pvs

List volume groups

sudo vgs

Verify physical volume(s) was created successfully

sudo pvdisplay /dev/<disk>

Verify the logical volume was created successfully

sudo lvdisplay


## Physical

Create physical volumes in LVM

```shell showLineNumbers=false
# example: sudo pv create /dev/sdb
sudo pvcreate /dev/<disk>

Volume

Create volume group based on physical volumes

# One physical disk in volume group
sudo vgcreate VolumeGroup01 /dev/sdb

# Multiple physical disks in same volume group
sudo vgcreate VolumeGroup01 /dev/sdc /dev/sdd /dev/sde

Logical

Create logical volumes based on volume group

# Allocate disk space for multiple volumes from same volume group
sudo lvcreate -n repos -L 30G VolumeGroup01
sudo lvcreate -n backup -L 50G VolumeGroup01
sudo lvcreate -n dev -L 100G VolumeGroup01

# Allocate rest of disk space
sudo lvcreate -n disk01 -l 100%FREE VolumeGroup01

Mount logical volumes

Format logical volumes and do it for all volumes

# example: sudo mkfs.ext4 /dev/VolumeGroup01/backup
sudo mkfs.ext4 /dev/<volume group>/<name of volume>

Create folders (optional)

# example: sudo mkdir -p /mnt/backup
# example: sudo mkdir -p /opt/{repos,backup,dev}
sudo mkdir -p /<path>/<name of volume>

Mount the disks

# example: sudo mount /dev/VolumeGroup01/backup /mnt/backup
# example: sudo mount /dev/VolumeGroup01/dev /opt/dev
sudo mount /dev/<volume group>/<name of volume> /<path>/<name of volume>

# Verify the mount was successful
df -h
# or
mount | grep <volume group>

Add to fstab to permanently add the disks

# use your editor of choice (nano, vi, vim, etc.)
sudo vim /etc/fstab

# Add the following
# example: /dev/VolumeGroup01/backup /mnt/backup ext4 defaults,nofail 0 0
/dev/<volume group>/<name of volume> /<path>/<name of volume> ext4 defaults,nofail 0 0
