Pls help with storage reassignment


May 16, 2023
Hi, I don't remember precisely (it's a home lab, I'm not an IT pro) why I had my system drive divided to a LVM-Thin volume ("data") and a Directory volume, but now I have the system on Directory (as expected) and the LVM-Thin volume is almost empty and unused. What I want to do is remove the LVM-thin volume and add the free space to the directory volume.

The situation is like this, the 54GB volume is the free one that I want to remove. The 39.6GB volume is the system volume I want to add the freed space to. Basically it's a 128GB SSD that I want to use all for the system. All VMs and LXCs are on a separate 1TB NVMe.

Can I just Destroy the "data" volume from GUI (<node>/LVM-Thin)? And if yes, then what? Thank you very much for any tips.

you should
1: shutdown the vm gracefully
2: detach the storage volume
3: boot the VM and make sure everything works and no data is missing
4: then destroy the volume.
The volume looks empty (definitely no VM or LXC on it) :) I'm asking if Proxmox saves anything on these or if it's safe to remove, AND how do I add this space to the system volume afterwards.
