Hi Matt,
I've tried both sync and async, the async returned " failed to close
.... input/out error".
But the final error point is still the "non-0 initial write position" in
librgw, which triggered by the unordered write.
Thanks

here's the strange thing, when I copy files from local fs dir, the problem
never appearance.
