Can't delete unused disks

[muzicman0]

I have 2 disks that are attached to a VM, but are unused. I can't delete them, as the system says they are in use. They are assigned to VM201, but originally I didn't have a VM201. Once I created the 201 VM, I ran a rescan to attach them so I could delete them, but they still won't delete.

What can I do?

Does the VM have snapshots? Please show the full message.

Here is the msg. I have backups on a PBS server, but no snapshots locally that I am aware of. How would I check? Thanks for the response!



[EDIT]I have 2 disks. the other one is .....-disk-1.

How would I check?

In the Snapshots tab of the VM.

Please post current VM configuration:
qm config VMID

As well as list of disks:
pvesm list STORAGE

Good luck

The error you are getting is directly from lvremove, i.e. on OS level.
It implies that the OS/Kernel has a lock/hold on the disk. Possibly outside of Proxmox.

First ensure that this disk is not used by any active VM, check other VM configurations.
The search your favorite engine for tips on determining why an LVM slice could be busy. There are multiple articles that list various steps.
A sure way to get this resolved is to reboot your node.

Good luck

a reboot did in fact fix it. Thanks.
