Is it possible to share the test you are running? As per your volume,
o-direct is not enabled on your volume, i.e. the file shouldn't be opened
with o-direct but as per the logs it is giving Invalid Argument as if there
is something wrong with the arguments when we do o-direct write with wrong
size. so I would like to test out why exactly is it giving this problem.
Please note that for o-direct write to succeed, both offset and size should
be page-aligned, something like multiple of 512 is one way to check it.
