My boot disk is a pair of mirrored 64Gig SSDs.

root@proxmox1:/dev/pve# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
data pve twi-aotz-- 27.62g 0.00 1.58
root pve -wi-ao---- 14.75g
swap pve -wi-ao---- <7.38g

root@proxmox1:/dev/pve# df /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/pve-root 15117272 13895752 431812 97% /

My problem is that my root partition is only 14.75G and it's full. (It was fuller, I just deleted some logs)
As I understand it, the data VL is mapped to the local-lvm storage and is a thin volume.
I don't use that - ever. Everything else is in a ZFS pool.

Can I somehow get rid of local-lvm and this data LV so that I can expand my root LV into the remaining space?

I tried running lvreduce on it, but apparently you can't do that on a thin volume.
