[SOLVED] LVM-Thin Pool Removal?

[BunkerHosted]

After changing my boot device on one of my nodes, from a 400GB SSD, to a 240GB SSD I am looking to free up some data in LVM as I must do this on 4+ other nodes.

While looking through configurations I notice that LVM-Thin is using 154GB of reserved space, using 0 actual space, and 8MB of metadata. We use ceph for storage so I am not 100% sure if this is safe to remove or not, any help would be greatly appreciated!

What is your conclusion on why it should not be safe to remove? Maybe I am missing something here.

I believe that this is safe to remove, I just am not 100% on why this is allocated as we are using ceph?

Sorry if this is a noob question, I am quite familiar with linux, but still getting accustomed to PVE.

The default installation by the Proxmox VE ISO will create a lvm-thin pool. It should be visible in the GUI as local-lvm.
