This testscript creates reflinks to files on different subvolumes, overwrites the original files and reflinks, and moves reflinked files between subvolumes. Signed-off-by: Koen De Wit <koen.de.wit@xxxxxxxxxx> --- Two new common/rc functions used in this script (_require_cp_reflink and _verify_reflink) have been submitted recently: http://oss.sgi.com/archives/xfs/2013-05/msg00745.html Changelog: v3 -> v4: Cleaning up commit message, cutting out filenames from output when printing md5sums, adding to group "reflink" v2 -> v3: Fixing wrapped patch v1 -> v2: Renamed 302 -> 316, changes made based on comments from Eric Sandeen: http://oss.sgi.com/archives/xfs/2013-03/msg00231.html tests/btrfs/316 | 131 ++++++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/316.out | 48 +++++++++++++++++++ tests/btrfs/group | 1 + 3 files changed, 180 insertions(+), 0 deletions(-) create mode 100755 tests/btrfs/316 create mode 100644 tests/btrfs/316.out diff --git a/tests/btrfs/316 b/tests/btrfs/316 new file mode 100755 index 0000000..321832a --- /dev/null +++ b/tests/btrfs/316 @@ -0,0 +1,131 @@ +#! /bin/bash +# FS QA Test No. btrfs/316 +# +# Testing cross-subvolume sparse copy on btrfs +# - Create two subvolumes, mount one of them +# - Create a file on each (sub/root)volume, +# reflink them on the other volumes +# - Change one original and two reflinked files +# - Move reflinked files between subvolumes +# +#----------------------------------------------------------------------- +# Copyright (c) 2013, Oracle and/or its affiliates.
