Unable to Recover Destroyed KVM

I accidentally deleted one KVM VM and I don't have any backup. Now I'm trying to recover it.

I'm using following procedure to recover.

Cloned Proxmox Node 900GB
dd if=/dev/sda of=/mnt/pve/backup/

Created a new virtual Proxmox Node restore Proxmox's Drive using dd. New node is same as my original node.

Found vg file.
cd /etc/lvm/archive/
I found pve_01253-2142000420.vg is matching
description = "Created *before* executing '/sbin/lvremove -f pve/vm-310-disk-1'"

Restored volume group
vgcfgrestore pve --force -f pve_01253-2142000420.vg

is showing my vm-310-disk-1 and correct size. Also I can see disk from Proxmox GUI local-lvm

Now I'm trying to create a VM and attach this disk
I'm getting following error. I can not create any disk.

lvcreate 'pve/vm-100-disk-2' error: Thin pool transaction_id is 1258, while expected 1247. (500)

Is there any way I can copy this disk from this node to another node or any fixes fro above error.
