Hi All,
I'm hitting the following issue while running Synthetic test case (from
store_test.cc) against bluestore:
store_test asserts on read data mismatch when read happens after the
zero-length write above object boundary.
Test case assumes all the data between the old and new object boundaries
are filled with zeros. But current bluestore write path implementation
simply discards zero-length writes and hence doesn't raise object size.
As a result subsequent read doesn't return anything above the old boundary.
The question is what's the proper fix for that:
1) Ignore zero-length writes in the test case and do not increase object
size/fill content on them.
or
2) Increase object content size on such writes in the bluestore.
Thanks,
Igor
