#2071 PR merged: RAWDISK output: improve device partition detection (e.g. Ubuntu 18.04)

Labels: enhancement, bug, fixed / solved / done

Pull Request Details:

  • Type: Bug Fix

  • Impact: Normal (creating RAWDISK output fails with "no space left on device")

  • Reference to related issue (URL):

  • How was this pull request tested? On Ubuntu 18.04.2 LTS

  • Brief description of the changes in this pull request:

On Ubuntu 18.04, it has been observed that after creating a loop device
and creating a properly sized VFAT file system >250 MB on it, after
mounting the file system size was actually just 30 MB. Reason: The
partition detection did not pick up the correct partition sizes of the
associated image file. This change uses losetup's --partscan option
(supported by util-linux v2.21 and above) to offer one additional
opportunity to detect partitions. If the option is not available, a
traditional losetup call will be used as a fallback.
