[ironic] Writing image to device /dev/sda failed

Hi all,

I have been playing around with ironic. However, I am not able to get the deploy of an image to write to the whole disk. It has been complaining about the same error of "Writing image to device /dev/sda failed with exit code 32. stdout: . stderr: lsblk: /dev/sda2: not a block device." Apart from that, I have tried to attached a physical pendrive to it and it's showing me another error stating "Installing GRUB2 boot loader to device /dev/sda failed with Unexpected error while running command.\nCommand: mount -o bind /dev /tmp/tmp5q03tchw/dev\nExit code: 32\nStdout: ''\nStderr: 'mount: /tmp/tmp5q03tchw/dev: mount point does not exist.\n'." Any help or directly is greatly appreciated.

Best, James
