Issue Expanding lv-root Storage on Fresh Proxmox Install

[AzzamSyakir]

Hi everyone, I'm new to Proxmox and need help expanding my node storage.

I did a fresh Proxmox install on a dedicated 120GB SSD. After installation, I noticed Proxmox created multiple partitions, with the last one using the LVM file system. Since I don’t need the default storage (lv-data) for VMs, I deleted it and extended lv-root to use the remaining space.

Now, when I run lvs, it shows lv-root has increased in size. However, df -h and the Proxmox web UI still show my root storage as 39GB.

How can I fix this? Also, can someone explain in simple terms why this happens?

I've attached some screenshots for reference. Thanks!

You might just need to extend the xfs part:

xfs_growfs /dev/mapper/pve-root

xfs_growfs /dev/mapper/pve-root

Oh, that worked!, thanks I also tried:

resize2fs /dev/mapper/pve-root

and it worked as well. So, does /dev/mapper/pve-root
represent the logical volume itself, or is it a mapping inside the LV? I'm not quite sure what it exactly stands for.

Far as I know it is a logical volume, and like on an actual partition there is a step to expand the file system when making changes. But I am not an LVM expert by no means lol Glad you got it sorted out!

because of the complexion with the lvm, i just use a regular filesystem on my virtal machine, thanks a lot
