Storage

To extend the ubuntu--vg-ubuntu-lv after increasing the size of a physical volume from Proxmox

For the purposes of simplicity, I’m going to assume that the main volume you wish to extend is /dev/sda3.

  • Check the current size with sudo lsblk or sudo fdisk -l
  • Run either sudo growpart /dev/sda 3 or use sudo cfdisk to resize the /dev/sda3 to max size
  • Extend the PV volume with sudo pvresize /dev/sda3
  • Extend the LV to 100% with sudo lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
  • Resize the filesystem with sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
