Hello so i try again :

root@plex:/home/stagiaire# dmesg | grep sda

so i try to expand my partition :

root@plex:/home/stagiaire# sudo parted /dev/sda

 3      1076MB  30.1GB  29.0GB                     lvm

I see the godd free space :

root@plex:/home/stagiaire# sudo fdisk -l /dev/sda | grep ^/dev

/dev/sda3  2101248 58720222 56618975  27G Linux LVM

Linux told me no free space :

root@plex:/home/stagiaire# sudo pvresize /dev/sda3
  /etc/lvm/archive: mkdir failed: No space left on device
  0 physical volume(s) resized or updated / 1 physical volume(s) not resized

my partition is still low :

what is wrong please ?

thanks

/etc/lvm/archive: mkdir failed: No space left on device

lvm failed because it wants to create a backup of its layout, but / is already full -> make some free space on / before you do the pvresize

Thanks, i found a way to make it my vm is now with a good space thanks

Hello!

The steps that issa2020 did worked out for me. The thing is, that I have to do these each time I would like to extend the VMs drive. Is there some update to proxmox that solves this?

We are running:
proxmox-ve: 7.1-1 (running kernel: 5.13.19-2-pve)
