Add new partion and add partion to existing LVM

1. Add new partion using fdisk

• sudo fdisk /dev/[drive containing partition you want to expand]
  • ex. if you want to expand partion sda3 you would use sudo fdisk /dev/sda
• use p to list partiton talble
  use F to list free space on drive
  use n to create a new partion
  use w to save changes

2. Add new partion to existing LVM

• use lsblk to list all drives, partitions, and LVMs

2.1 Create a new physical volume (pv)

• sudo pvcreate /dev/[partiton you want to use]
  • ex. sudo pvcreate /dev/sda4

2.2 Identify the volume group (vg) you want to use

• you can use sudo vgs to list all available volume groups

2.3 Extend volume group

• sudo vgextend [volume group] /dev/[partition]
  • ex. sudo vgextend ubuntu-vg /dev/sda4

2.4 Identify the logical volume (lv) you want to use

• you can use sudo lvs to list all available logical volumes

2.5 Extend logical volume

• sudo lvextend -l +100%FREE /dev/[volume group]/[logical volume]
  • ex. sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

3. Resize filesystem so system sees changes

• sudo resize2fs /dev/[volume group]/[logical volume]
  • ex. sudo resize2fs/dev/ubuntu-vg/ubuntu-lv

Expand existing partion

1. sudo growpart /dev/[disk] [partition number]
   • ex. sudo growpart /dev/sda 3
   • note the space between disk and partion number
2. sudo resize2fs /dev/[partition]
   • ex. sudo resize2fs /dev/sda3

Expand existing LVM to use whole partition

• sudo lvextend -l +100%FREE /dev/[volume group]/[logical volume]
  • ex. sudo lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
