Can't delete a LVM?

[Nanja]

I seem to be having issues deleting this. I currently have no VM or CT up and running, so it shouldn't be in use.
Whatever I do, it says cannot be deleted or file system in use. I tried rebooting several times and it wouldn't work.

I followed all the options here in this guide. I just can't seem to get it to work.

  --- Logical volume ---
  LV Path                /dev/dedi-vg/root

Any help would be appreciated =D
unmounting also doesn't help, because it's in use.

Hi,
first of all are you sure that this is not your default LVM, also used for PVE? Can you share the output of lsblk -o +FSTYPE

 

[Nanja]

eh, I followed this guide.

wipefs -fa /dev/sda5
dd if=/dev/zero of=/dev/sda5 bs=1M count=1000
udevadm settle
reboot

So I can't check anymore, I can't even boot the machine. I don't have IPMI so I can't reinstall OS on this unmanaged dedicated server. Waiting to see how much this company charges me for a reinstall.

Well, seems like you wiped your system disk, including PVE...

I hope you get a free of charge reinstall.
