      The failure is strange, because we are running "parted -s" which means do not prompt user for input but it does this anyway and fails. Running the commands manually works just fine without the "-s" option.

      The version of parted used on "warrior" is 3.2, which is from 2014. I have tested using parted 3.3 (from 2019) and it does work and this error is not shown so I suspect it is a parted bug in the way it handles GPT images. As this have shown to work without any issues on MBR images.

      Actually was not related to parted version, and the problem was missing backup GPT partition table at end of disk. This needs to be in place for "parted resizepart" to work.
