The mount option has precedence. As in, if you set it to datavolume,
the database will do odirect ios. As in, atleast odirect. It will do
odirect+async if that filesystemio_option is set to setall.

In your case, moving the script to a non-datavolume is easiest as you
could do it without having to remount the volume.

BTW, if you do remove the datavolume mount option, do remember
to set the filesystemio_options to atleast odirect (or directio) if not
setall. Do not leave it at async.
