Extending an LVM storage pool in Proxmox

Format the drive

First, list the available disks:

fdisk -l

Format the disk you want to add, creating a partition, in this case we will create sdf1 on the disk sdf:

cfdisk /dev/sdf

Create a physical volume

pvcreate /dev/sdf1

Extend it:

vgextend pve /dev/sdf1

lvextend /dev/pve/data -L +7.3T

(Replace +7.3T with the size of the disk space being added)

Done!
