Hi @all,

i have a question regarding my installation

My local hard drive crashed and I had to reinstall Proxmox completely. My NVME with the VM disks is still intact.
I found a post telling it is possible to create a new placeholder VM and use "qm set <vmid> <new vmid>.

My problem is, the NVME disk is completely full and I only have 130MB left of disk space. qm set is complaining when trying to migrate the disk. Is it possible to delete an old "unreferenced" VM on the NVME i don't need anymore? How?

I mostly want VM104 with 406G back again, since it is my Immich VM. I have backups, but it would be a pain to restore everything and copy it when all the data is still present.

Sorry if I didn't explain it well enough.

It's more like in this case:

[SOLVED] Thread 'Recovery VMs from LVM Disk'

Hello.

I have an LVM SSD disk, which contains a VM Disk. However, the VM is not shown in the Proxmox sidebar. How can I recover the VM from here?

I have a MINI PC with an SSD (the proxmox host, alias local) and an NVME having all of my VMs. The local SSD crashed totally, not recoverable with broken sectors and all. I bought a new one and freshly installed Proxmox. But the data on the NVME drive is still there.

I tried to follow the guide in the post mentioned above but my error message is "Not enough space on drive NVME" since I guess I need some space additionally to move and copy around the data. The old SSD was 128GB, the new local SSD is 1TB, so I created a new VM on the SSD and then tried to move the still existing, but not referenced NVME VM disk to this one.

Is it more clear now?
