Trying to restore backup.

[8BitHero]

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.

So.. using what I found in:
https://forum.proxmox.com/threads/vma-archive-restore-outside-of-proxmox.14226/

I've managed to unpack, and create a .conf file, a .fw file, and 2 .raw images. One 36gb, and one 136gb.

Now to figure out how to import these .raw files into the VMs.

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

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

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.
