It was a virtio disk instead of SATA/SCSI.

No, that was the full output. There is no by-id folder unless I attach a SATA device to a VM for example.

It may be a corner case of using virtio disks only. But I think if disk.DeviceID is not found, it shouldn't proceed further like executing dd at least.

I agree there needs to be better handling for the case where there's no /dev/disk/by-id/x
OTOH I'm also curious on why that disk wasn't found (using virtio shouldn't be a problem) -- if that disk indeed does exist?
If so, would you be able to provide some diagnostics @nobuto-m ?
sudo lsblk -f
sudo blkid /dev/vdc

Thanks @nobuto-m . Is the output of the ll /dev/disk/by-*/ truncated? Seems it's missing the by-id folder?
