Using a .raw file as the hard disk for a VM.

lolloandr · Nov 10, 2023

Hello, i have this configuration:

- ssd with proxmox installe

- raid of 4 disk acting as the storage for the VMs

My SSD failed and i replaced it with a new one and installed proxmox, now i need to get my machines running again. Proxmox automatically picked up the raid (see here) but i don't see any obvious way to use these images as hard drive for my VMs. What i am missing?

Thank you

Hello

Could you share your /etc/pve/storage.cfg with us and also the config of the vm you want it to share to (/etc/pve/qemu-server/<VMID>.conf)?

lolloandr · Nov 10, 2023

Sure, here you go:

/etc/pve/storage.cfg

Code:

dir: local
        path /var/lib/vz
        content backup,vztmpl,iso

lvmthin: local-lvm
        thinpool data
        vgname pve
        content rootdir,images

lvm: bigData
        vgname bigData
        content rootdir,images
        shared 0

/etc/pve/qemu-server/100.conf

Code:

boot: order=scsi0;ide2;net0
cores: 1
cpu: x86-64-v2-AES
ide2: none,media=cdrom
memory: 2048
meta: creation-qemu=8.0.2,ctime=1699611923

That are your logical volumes, please post the output of pvdisplay, vgdisplay and lvdisplay

You do not have declared disk on bigData: storage. You changed this name to vm-100-disk-1?

Yes, that sounds like a good idea.

I tried, it won't boot. The vm bios could't find a bootable image.

Sorry for the late reply and thank you for your help!

Have you tried to simply add

Code:

scsi1: bigData:vm-100-disk-0,iothread=1,size=32G

to the vm config file?

Hi, I tried. This is what i get:

This is the config file:

Code:

boot: order=scsi0;ide2;net0
cores: 1
cpu: x86-64-v2-AES
ide2: none,media=cdrom
memory: 2048
meta: creation-qemu=8.0.2,ctime=1699611923
name: local
net0: virtio=6A:81:9E:1D:45:3D,bridge=vmbr0,firewall=1
numa: 0
ostype: l26
scsi0: vm-112-disk-0,iothread=1,size=32G

And this is a screenshot of the drives i have:

Philipp Hufnagl · Nov 17, 2023

There seem to be 2 disks associated with vm-100
but in your config file I only can see scsi0: bigData:vm-100-disk-1,iothread=1,size=32G

Have you tried adding BOTH disks to the /etc/pve/qemu-server/100.conf ? Something like

Code:

boot: order=scsi0;ide2;net0
cores: 1
cpu: x86-64-v2-AES
ide2: none,media=cdrom
memory: 2048
