Hi all,

I'm new to Proxmox, I need some help.
BY mistake, when installing Proxmox on my server, I allowed Proxmox to auto split the drives as it wanted, without realizing that now I have a very small partition for backups.

I have two drives:
sda: 2.2TB
sdb: 2.2TB

sdb is fully used for VMs
sda was supposed to be used for ISO and backups, but Proxmox split it into two 'local' (100GB) and 'lvm-thin'(2TB), and is allowing me to store backups only on 'local'

How can I fix this, remove LVM-thin and expand 'local'? If yes, how?

Some terminal output:
sda 8:0 0 2.2T 0 disk
├─sda1 8:1 0 1007K 0 part
├─sda2 8:2 0 1G 0 part
└─sda3 8:3 0 2.2T 0 part

Dont beat yourself up about not doing the best partitioning at the time of the install. You are not the first one, so the topic has been covered a lot. This google search may help "proxmox remove local-lvm and expand root"
A few sample results:

WOW, three lines of code, and the job is done:
lvremove /dev/pve/data
lvresize -l +100%FREE /dev/pve/root
resize2fs /dev/mapper/pve-root


Massive THANK YOU :)
