From: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx> This set of tests verifies that it is possible to add an internal bitmap to an existing array, and that the device can be written to after the bitmap is added. This should catch cases such as the one fixed by 4474ca42e2577563a919fd3ed782e2ec55bf11a2 Signed-off-by: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx> --- tests/05r1-add-internalbitmap | 20 ++++++++++++++++++++ tests/05r1-add-internalbitmap-v1a | 20 ++++++++++++++++++++ tests/05r1-add-internalbitmap-v1b | 20 ++++++++++++++++++++ tests/05r1-add-internalbitmap-v1c | 20 ++++++++++++++++++++ 4 files changed, 80 insertions(+) create mode 100644 tests/05r1-add-internalbitmap create mode 100644 tests/05r1-add-internalbitmap-v1a create mode 100644 tests/05r1-add-internalbitmap-v1b create mode 100644 tests/05r1-add-internalbitmap-v1c diff --git a/tests/05r1-add-internalbitmap b/tests/05r1-add-internalbitmap new file mode 100644 index 0000000..80ce9f5 --- /dev/null +++ b/tests/05r1-add-internalbitmap @@ -0,0 +1,20 @@ +# +# create a raid1 without any bitmap, add the bitmap and then write to +# the device.
