In proxmox I have a ZFS storage defined
id: hdd_dimgs
ZFS Pool: hdd/pmx/dimgs
(Proxmox calls this ZFS Pool, but it should really be labelled ZFS Dataset)

I get the error at the top of this post when doing any of these
`qm rescan`
`qm rescan --vmid 105`
`qm rescan --vmid 106`

Both VM's work 100% fine. It's just this error is not nice, but it does not seem to cause any actual issue that I've noticed.

`qm rescan --vmid 107` does not produce any error.

106 and 105 were produced by Proxmox using the web GUI to create them from the 107 template. I have not edited their disk lines in the config, they are exactly as Proxmox created them.

Solved. It doesn't like having datasets 3 levels deep. Only 2 (one below the root dataset)

I changed it to
hdd/pmx-dimgs

Ive literally been pulling my hair our tring to solve this issue and nobody talks about this bug but your comment saved me. My VM is working now. I even registered an account just to leave this comment. Thank you whoever you are.

so the qcow2 file needs to be 2 folders deep or less.
