[SOLVED] How to get rid of phantom snapshots

[muekno]

One of my VMs does not show any snapshot in GUI
qm list <VID> snaphot shows no snapshot, just you are here
zfs list -t snapshot does only list one of another VM
But looking at the VM store show me 3 snapshots, 2 for the VM that shows none not in GUI not in qm list, and the one of teh other VM shown in GUI too
trying to delete the phantom snapshot by remove from the VM store, don't let me to, as there still exists a VM with that VID.

Tried to clone the VM (12G in size), stops after 3.7G but but continues with message 3.7G fom 12G copied in x seconds and so one, but 3.7G stays for ever.
Triying a snapshot fails,
Triying a back up fail, does not finish

The VM iz self runs fine, but holds a central configuration for a lot of server, so it is important

Hi,

Please provide us with the VM config `qm config <VMID>`

Thank you for the output!

What Proxmox VE version are you running `pveversion -v` if you're sure to remove the snapshot, you can edit the VM config file in the `/etc/pve/qemu-server/VMID.conf` and delete the section of the snapshot you want to remove

 

[muekno]

Version 8.2.2 latest patches.

Thanks for quick answer and help, the snaps are old, not needed any more

Best Regards

Rainer

Yes, edit the VM config and delete the following section from it:

Make sure that you have a backup of the VM config in order if you did any mistake.

Hello,

removed the lines you noted, yesterday. Did restarted the VM, VM works still fine, but in VM_Space I can still see the Snapshots, but still not in the VM. Waited till this morning hopeing they will dissapear, but they did not and are still not deletable.

Kind Regards

Rainer

 

[Moayad]

May you post the output of `zfs list`?

the two 502 snapshots are the problem

Kind Regards

[Moayad]

If you are sure that you really not need those snapshots, you can delete them using the following command:

zfs destroy VMs/vm-502-state-before-local-backup
zfs destroy VMs/vm-502-state-before-update

Make sure that you have a valid backup for the VM before you remove them.

 

[muekno]

Thank you so much, it worked

Kind Regards
