Hi there,

Today I move my proxmox installation from a SATA SSD to a NVMe SSD. Then I plugged the SATA SSD into a linux laptop via a SATA to USB adapter and tried to wipe the drive via gparted. But gparted told me, that there is a active LVM group and that wiping the drive is not recommand.

I already tried some commands, but I ran into issues.

This is shown, when I run lvdisplay:
Code:
root@linux:~# lvdisplay pve
  WARNING: Not using lvmetad because a repair command was run.
  --- Logical volume ---

....

And the lvs -a command
Code:

When I try to remove one of the logical volumes, I get an error:
Code:
root@linux:~# lvremove /dev/pve/vm-100-disk-2
  WARNING: Not using lvmetad because a repair command was run.
Do you really want to remove and DISCARD logical volume pve/vm-100-disk-2? [y/n]: y
  /usr/sbin/thin_check: execvp failed: No such file or directory
  Check of pool pve/data failed (status:2). Manual repair required!
  Failed to update pool pve/data.

When I try to repair it, this happens:
Code:
root@linux:~# lvconvert --repair pve/data
  WARNING: Disabling lvmetad cache for repair command.
  WARNING: Not using lvmetad because of repair.
  /usr/sbin/thin_repair: execvp failed: No such file or directory
  Repair of thin metadata volume of thin pool pve/data failed (status:2). Manual repair required!

I don't care about the data on the disk. How can I repair the disk?
I guess i broke the thin pool by trying to repair it :facepalm:

Thanks!

After a reboot of my linux machine, I was able to run lvremove on all logical volumes and finally was able to remove the volume group completely
