All this could be accomplished with a single line: _cp_reflink $SCRATCH_MNT/foo $mnt1/bar And then have the golden output expect an error message. That's the most standard and prefered way to do things in fstests. No need to redirect stdout and stderr to a temporary file, check return value, check the temporary file, etc... > + > + check_fsid ${SCRATCH_DEV_NAME[1]} > +} > + > +mount_cloned_device Really, why have all the test code inside a function that is called only once? Get rid of the function...

If another device with the same fsid and uuid would mount then verify if it mounts with a temporary fsid.
