I have a cluster with 3 hosts using CEPH and NFS storage.

I have been facing a problem for the last 72 hours.

When I destroy a VM, if I use "--destroy-unreferenced-disks --purge" the VM is not completely deleted.
Only the disks are deleted, the configuration remains.

Example:
Code: 
root@cmt5923:~# qm destroy 13775 --destroy-unreferenced-disks --purge

Can you check to try to delete the vm again after the first deletion and post the error here? I had something similiar last week and Im in contact with proxmox. Your logs and insights might help fixing this problem.

What happens if you attempt to do the same thing from the GUI?

What about: rbd -p {pool} ls -l and if theres a image left (at my side there was still a cloud init image for example):
rbd -p {pool} rm {image} do you have krbd = 1 (enabled?)
 
I solved the problem completely randomly.
This problem was related to nfs storage. Even though it was connected to nfs storage, its access was not healthy.
When I restarted the nfs server, the problem was automatically solved.
