Unable to delete an unused VM disk and a non-existent VM disk

Globul · May 19, 2023

Hi,

I have 2 disk that i can't delete.

The first one refers to an old VM that no longer exists and another disk is marked as unused in the VM. The VM is stopped but I can't delete it.

Hi,

what exactly is the issue that you're encountering? Are there any error messages you get? How did you try to delete the disk?

In both case, i have :
lvremove 'pve/vm-102-disk-0' error: Logical volume pve/vm-102-disk-0 in use.

The VM 102 don't exist.

In the other case, same message but the disk i want to delete is unused in the config.

Hi, Can you help me ?

I've try several things i found in the forum with no success.
I try to delete the disks from the GUI and from the CLI, i always have the same result.

Hi,
what does fuser -vau /dev/pve/vm-102-disk-0 show? If there's no result, you can try

Code:

root@pve701 ~ # ls -l /dev/pve/vm-102-disk-0
lrwxrwxrwx 1 root root 8 May 31 10:31 /dev/pve/vm-102-disk-0 -> ../dm-20
root@pve701 ~ # ls -l /sys/block/dm-20/holders

Note that the number for dm-20 will (most likely) be different for you.

Sorry it is lvremove /dev/pve/vm-102-disk-0, the name of your volumegroup

Hi,
thanks for your reply...

Still doesn't work ... Disk in use and there is no VM 102

Code:

Same things for vm-108-disk-0 (unused disk of vm 108)

This is showing you that the logical volume in question is mapped (active.)

can you post the output of:
1. /etc/pve/qemu-server/102.conf
2. qm list
3. vgs

I dont know how you have a vm running without a config, but it is running

you can stop it using qm stop 107
reading comprehension, yadda yadda

lvchange -an pve/vm-102-disk-0
then run lvscan to verify that the lv is inactive
then lvremove pve/vm-102-disk-0

well, if you cant lvremove it following a reboot you're going to need to boot to a livecd. I honestly have no clue why the logical volume is active.
