From b04fe27eda770a7c56c77dc0102553ffddddfdb9 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 15 Apr 2020 14:49:16 +0800 Subject: [PATCH] btrfs: snapshot creation with qgroup inherit would mark qgroup inconsistent Test that a new snapshot created with qgroup inherit passed should mark qgroup numbers inconsistent. Such inconsistent flag is required to show that we need a qgroup rescan to make qgroup numbers correct again. This is unavoidable since snapshot creation with qgroup inherit acts as snapshot creation + qgroup relationship assign. See btrfs(5) for why such operation needs qgroup rescan. This test failed on current kernel, the fix is submitted to the btrfs mail list titled: "btrfs: qgroup: Mark qgroup inconsistent if we're inherting snapshot to a new qgroup" Signed-off-by: Qu Wenruo Reviewed-by: Filipe Manana Signed-off-by: Eryu Guan --- tests/btrfs/210 | 62 +++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/210.out | 2 ++ tests/btrfs/group | 1 + 3 files changed, 65 insertions(+) create mode 100755 tests/btrfs/210 create mode 100644 tests/btrfs/210.out diff --git a/tests/btrfs/210 b/tests/btrfs/210 new file mode 100755 index 00000000..daa76a87 --- /dev/null +++ b/tests/btrfs/210 @@ -0,0 +1,62 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2020 SUSE Linux Products GmbH.
