[Bug 1490608] Re: parted allows to fix broken GPT only interactively

[Phillip Susi]

I've been aware of this for a few years now since I first added the
feature and sebner wanted to use it in the cloud-init-tools to do just
that.  The problem is that the exception handler only gets a text
description, so you would need to do a loose string comparison to
identify the particular exception you want to auto accept.  You then
need a way to specify this with a command line switch.  I'm not liking
the idea of parted --force-not_all_of_the_space_available....

Also the exact text is subject to change between releases, and changes
depending on your locale, so it gets really tricky.

Title:
  parted allows to fix broken GPT only interactively

Status in parted package in Ubuntu:
  Triaged

Bug description:
  when physically resizing a disk (i.e. because it is a kvm image where
  you dd zeros to the end or because you dd'ed an image from a smaller
  disk to a bigger one) the GPT backup at the end of the device sits in
  the wrong sectors ...

  while parted offers you a yes/no question in interactive mode to fix
  this, there is no way to make use of this feature when using "parted
  -s" (scripted mode). parted should get an option to fix the GPT even
  when using it non-interactively i.e. from a "grow rootfs at first boot
  to full disk size" script.
