This test case will emulate this corruption by xfs_db and use xfs_repair to fix it. Signed-off-by: Zorro Lang --- Hi, V2 did below changes: 1) remove the requirement for xfs_db's write and addr commands 2) check if xfs_db support write -d option 3) turn to get filesystem block size from _filter_mkfs output 4) add more comments Thanks, Zorro tests/xfs/288 | 110 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/288.out | 2 + tests/xfs/group | 1 + 3 files changed, 113 insertions(+) create mode 100755 tests/xfs/288 create mode 100644 tests/xfs/288.out diff --git a/tests/xfs/288 b/tests/xfs/288 new file mode 100755 index 0000000..81e7b50 --- /dev/null +++ b/tests/xfs/288 @@ -0,0 +1,110 @@ +#! /bin/bash +# FS QA Test 288 +# +# When an attribute leaf block count is 0, xfs_repair should junk +# that leaf directly (as xfsprogs commit f714016). +# +#----------------------------------------------------------------------- +# Copyright (c) 2017 Red Hat Inc.
