Hi,
I had issues with boot loader and kernel upgrade with migrating from version 7 to 8.
Wiped and re-installed ProxMox 8. My vmdata LVM is still available but I cannot access or create a VM. Is there a way to recover, get access to the partition with VM data? Or wipe? Getting error 500 when trying to wipe because of LVM, of course. Here is the result:


Code:
root@pve-labs:~# lvs
  LV            VG     Attr       LSize    Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert

Ahhh I was able to remove the LV and the VG using lvm command. Then I could wipe the disk using the graphic interface or could have worked with dd /dev/zeros I guess. Anyway, it worked.
Next step was to initialize the disk with GPT and now I can finally create a new LVM-thin and re-create VMs!
