Extend LVM disk for virtual machine server or any server

I am doing this on proxmox

1) login to the proxmox server

2) cd to the disk you need to expand

[box] cd /var/lib/vz/images[/box]

3) Increase the disk size

[box] qemu-img resize diskimage.zzz +[size in GB you want to expand]G[/box]

4) boot your VM with gparted or partition magic live iso

5) expand the volume to the new size

6) reboot the VM normally

7) run command


8) note the "VG NAME"

9) run
[box]lvextend -L+[size in GB you want to expand]G /dev/{insert VG NAME]/root[/box]

10) Done!
