Example OS: Ubuntu

Make sure to adjust the LV, PV, dev name before run the command.

Resize in Proxmox UI

Resize the file system in UI, under VM -> Hardware -> Click on the disk to resize, click “Resize disk” button.

Check Capacity on Partition

Confirm increase in disk space (1TB in my case):

lsblk

Output:

NAME                      MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda                         8:0    0    1T  0 disk
├─sda1                      8:1    0    1M  0 part
├─sda2                      8:2    0    1G  0 part /boot
└─sda3                      8:3    0    1T  0 part
  └─ubuntu--vg-ubuntu--lv 253:0    0   31G  0 lvm  /

Resize Partition

Resize the partition using parted

sudo parted

Output:

GNU Parted 3.3

Expand LV

Extend the logical volume now

sudo lvextend -r -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv

Output:

  Size of logical volume ubuntu-vg/ubuntu-lv changed from <31.00 GiB (7935 extents) to 1.03 TiB (270079 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.

The filesystem on /dev/mapper/ubuntu--vg-ubuntu--lv is now 276560896 (4k) blocks long.

Expand PV

Resize the physical volume (may or may not need)

sudo pvresize /dev/sda3

Output:

Physical volume "/dev/sda3" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized

Check Capacity on Partition after Resizing

Confirm resize complete

$ lsblk

Output:

NAME                      MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda                         8:0    0    1T  0 disk
