Resize storage pool with new disk

[kenaddams42]

Hi,
I am new to Proxmox and LVS, and I hope someone will be able to help.

I run out of space, see below.

I am not really familiar with LVS yet but I understand, new 3 VMs are virtually allocated 32Gb and only use 60.7G.

I also understand 13.87Gb are available to resize any of these volumes, right ?

Now, I added a new disk (recognized as /dev/sda and the former disk where Proxmox is installed on /dev/sdb):





Can I extend my "local-lvm" storage with the new disk space ?




Thanks, and stay safe

Replying to myself - I found this tuto describing how to add a new partition to a Volume Group in order to expand free space.
It is based on Debian commands but it works well.

Just use lvextend -l +your_sizeG-v /dev/mapper/pve-data at the end to resize the data volume.
