VM ID changed, now OS won't boot

[eiger3970]

I changed the VM ID and now the 2 VM's OS Console shows error:
Volume group "VolGroup00" not found
The other VM is trying to run a new install.

I followed this process to rename the VM IDs. Funnily enough, there were no files in /var/lib/vz/images.

Stop VM > Yes > SSH into Proxmox < $ cd /var/lib/vz/images > $ mv xyz abc > $ cd abc > $ mv vm-xyz-disk-1.qcow2 vm-abc-disk-1.qcow2 (or .raw) > $ cd /etc/pve/nodes/proxmox/qemu-server > $ mv xyz.conf abc.conf > $ vim abc.conf > change line local:xyz/vm-xyz-disk-1.raw,format=raw,size=30G to local:abc/vm-abc-disk-1.raw,format=raw,size=30G > Save > view Proxmox with new VMID.

hi,

probably you assigned the disks wrongly.

Funnily enough, there were no files in /var/lib/vz/images.

what did you mv then if there were no disks?

official way to change VMID is through cloning or backup&restore

I simply moved the VM IDs from 150 149 148 147 146 145 144 143 142 142 to 141 142 143 144 145 146 147 148 149 150.
I'll have to research how to clone or backup&restore after I rescue Proxmox.

I've just noticed the 141.conf - 150.conf files are in two different locations:
/etc/pve/nodes/proxmox/qemu-server (these are the conf files I renamed).
/etc/pve/qemu-server (I didn't touch these conf files).
/var/lib/vz/images (used to be here, but weren't there even before I started the renaming).

So:
141 was renamed 144.
143 was renamed 146.

I restored the two VMs. Would like to know how to change the numbers now though.

 

[eiger3970]

Ran a backup and restore with a new VMID.
Worked on VM 143.
The 2nd backup/restore with a new VM 144 would boot up a wrong OS?

 

[eiger3970]

Ok, had to Remove newly restored VM 144, then restore again.
Seemed to have removed the previous VM's OS.
