'Unrecognised disc label' - when using parted with qemu images

  • 772

I have a Linux from scratch LiveCD running on qemu vm. I'm using this command to create a hda disc for qemu:

qemu-img.exe create -f qcow2  base-linux.img 5G

Then I run my vm:

qemu.exe -m 1024 -boot d -cdrom lfslivecd-x86-6.3-r2145.iso -hda base-linux.img

After booting I try this command:

parted /dev/hda unit GB mkpartfs primary ext3 0 5

And it gives me the 'unrecoginised disc label error'.

I'm using parted 1.9.0 and have no ideas as to how to fix it.

linux qemu parted

    You probably need to make a label on the disk first.

    Try just running parted manually:

    parted /dev/hda
unit GB
mklabel msdos
mkpartfs primary ext3 0 5

  2. If you want to do what @James recommended via the cli you can do the following:

    $ parted /dev/sde --script -- mklabel msdos
$ parted /dev/sde --script -- mkpart primary 0 -1

    This was of course on a smaller HDD (1TB) so as was mentioned in the comments, anything over 2TB will require a different label, and yes you should be using GPT for that.

    $ parted /dev/sde --script -- mklabel gpt
