I am transferring local files to xrootd using xrdcp. If two clients write
to the same file in xrootd (at the same time) they succeed and the file in
xrootd is a mixture of the two local files. I guess that this behavior
is due to the use of kXR_force in the open call. In this case
all file usage rules are ignored (from the xrootd Protocol manual) and
many clients can open the same file (and step on each other's toes).
Is this needed at all or could one use kXR_delete to overwrite a file?
