Trying to restore backup.

I've managed to stumble my way through setting up Proxmox, and migrating my old ubuntu server 12.04 webserver into an LVM.

I've been doing a number of backups on the way, stopping the VM, and using the backup function.

Ubuntu was nagging me to update to the latest and greatest, and I figured I'd give it a shot, because I could always roll back. The update fell apart, and broke a bunch of services.

When I try to restore the proxmox created image I get:

Virtual Environment 4.3-1/e7cdc165
Virtual Machine 100 ('VM 100' ) on node 'HPServer'

When I check the storage VMStorage, it is 136.7GiB free. The VM does contain 2 seperate "Drives", one OS (32GB), and a data drive (146GB). It looks like it is trying to unpack both images into VM_Storage, and not restore the 2 images to the separate 2 drives like it supposed to.

I've googled, and searched these forums, I did not see this error come up.

Thanks for any help.
 
I was able to manually restore the 2 extracted raw files using

dd if=disk-drive-ide0.raw of=/dev/VM_Storage/vm-100-disk-1
dd if=disk-drive-ide1.raw of=/dev/Webserver_Storage/vm-100-disk-1

So it backs up the images correctly, and splits them into 2 files for each drive.
It just doesn't unpack them correctly, and tries to put them both into the first drive (in this case VM_Storage) instead of 1 into VM_Storage and the other into Webserver_Storage.

how did you restore? with the gui? there you can only choose one storage, so all the disks get restored there
on the cli you can provide a storage per disk AFAIK

Instead of backing up the entire VM image, since it won't restore properly, is there a way to just backup the single drive?

you can choose the 'no backup' option in the gui on a disk

I manually unpacked the vma file, then DD'd the raws into the 2 drives VM_Storage and Webserver_storage.

I guess not many people split a VM over 2 drives. OS and data.
