FYI, I've just pushed this new test: >From ac211788f362b580f8ee508cacd40fa4a809a3cb Mon Sep 17 00:00:00 2001 From: Jim Meyering <[email protected]> Date: Sat, 19 Sep 2009 08:22:20 +0200 Subject: [PATCH] tests: resize FAT and HFS file systems
Since it looks like we're stuck with keeping at least FAT and HFS file-system resizing support in libparted, we have an obligation to exercise at least some of that functionality. For now, I've limited this test to shrinking well-aligned partitions by a well-behaved amount. Curtis Gedak helped come up with a usable test. * tests/t3000-resize-fs.sh: New file. Use starting partition offset that is on a cylinder boundary, and increase the partition size to be larger than 256 MiB. When resizing, choose the new size to be exactly one cylinder (8MiB) smaller than the original. --- tests/t3000-resize-fs.sh | 95 ++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 95 insertions(+), 0 deletions(-) create mode 100755 tests/t3000-resize-fs.sh diff --git a/tests/t3000-resize-fs.sh b/tests/t3000-resize-fs.sh new file mode 100755 index 0000000..0620a5e --- /dev/null +++ b/tests/t3000-resize-fs.sh @@ -0,0 +1,95 @@ +#!/bin/sh + +# Copyright (C) 2009 Free Software Foundation, Inc. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
