Mounting old Proxmox HDD to new installation

Hello all!

Let me explain my situation. I have a server with two spinning HDDs (hardware RAID, so they show as a single drive to the system) where I installed Proxmox. So this drive is a boot drive, it has root file system as well as all my virtual machines and containers.

Now I added a pair of SSDs. I unplugged the old drives, not to corrupt them. I installed Proxmox on these new SSDs and used ZFS RAID1 option during the installation. The installation went well and I can log into the web GUI of the new deployment. I connected back the old spinning drives and I want to access VMs from the old drives. However, I was not successful.

I used the solution provided by the original author of this reddit post https://www.reddit.com/r/Proxmox/comments/w8o7va/import_old_lvm_storage_drive_to_new_proxmox/
I got so far as to add the LVM, however, that's where my luck ended here:

(sda1 is the old drive I want to access)

New storage:
Code:
root@proxmox:~# cat /etc/pve/storage.cfg  
dir: local
        path /var/lib/vz
        content vztmpl,backup,iso

zfspool: local-zfs
        pool rpool/data
        content images,rootdir
        sparse 1
Old storage:
Code:
dir: local
        path /var/lib/vz
        content iso,vztmpl,backup

lvmthin: local-lvm
        thinpool data
        vgname pve
        content rootdir,images
My goal is to mount the local-lvm from the old drive to be able to access VMs stored there



Has anyone dealt with anything similar before and managed to solve it?
