This funtionality wasn't available in 1.5, so, yes, this would only
have started with 1.7.

So it seems that these netapp drives somehow don't understand the
entirely normal FileDispositionInformation method, or they ignore it for
some unknown reason.

Unfortunately the strace from your OP isn't helpful since it
only contains the deletion of a single file.  What would help is
an strace of a rmdir or rm -rf(*) of a directory which then creates
one of those temporary directories.  There are lots of potential
debug messages wqhich might sched a light here.


(*) If possible with not more than a single file in the dir, so that
    the strace doesn't become too big.
