In fact, this currently causes a mkfs failure (missing $) that we don't detect because we aren't checking that the mkfs actually succeeds. All we need to do here is: _scratch_mkfs >> $seqres.full 2>&1 || _fail "mkfs failed" If you dig down into _scratch_mkfs(), you'll see that it already includes $MKFS_OPTIONS and thus formats the fs as specified by the test config. It might also be a good idea to check that the _scratch_mount below succeeds as well... > +_scratch_mount >> $seqres.full 2>&1 > +length=$(($BLOCKS * $BSIZE)) > + > +# Write file > +$XFS_IO_PROG -f -c "pwrite 0 $length" -c fsync $src > /dev/null > +cp $src $dest > + It seems quite unlikely for this to not create a single extent given the smallish file size and freshly created fs, but who knows with various fs types, test configurations, test device sizes, etc. Another option could be to check the starting extent count and verify the ending extent count matches, rather than assume hardcoded values of 1. To be honest, even just including the starting extent count in the golden output (e.g., add an fiemap command here as well) might be good enough to distinguish that failure path from something going wrong in the collapse path, should it ever occur. > +# Insert alternate blocks > +for (( j=0; j < $(($BLOCKS/2)); j++ )); do > + offset=$((($j*$BSIZE)*2)) > + $XFS_IO_PROG -c "finsert $offset $BSIZE" $dest > /dev/null > +done > + > +# Check if 100 extents are present > +$XFS_IO_PROG -c "fiemap -v" $dest | grep "^ *[0-9]*:" |wc -l > + > +_check_scratch_fs > +if [ $? -ne 0 ]; then > + status=1 > + exit > +fi > + > +# Collapse alternate blocks > +for (( j=0; j < $(($BLOCKS/2)); j++ )); do > + offset=$((($j*$BSIZE))) > + $XFS_IO_PROG -c "fcollapse $offset $BSIZE" $dest > /dev/null > +done > + > +# Check if 1 extents are present > +$XFS_IO_PROG -c "fiemap -v" $dest | grep "^ *[0-9]*:" |wc -l > + > +# compare original file and test file. > +cmp $src $dest || _fail "file bytes check failed" > + > +_check_scratch_fs > +if [ $? -ne 0 ]; then > + status=1 > + exit > +fi > + > +umount $SCRATCH_MNT > + The scratch device is unmounted and checked after each test that uses it so the above is unnecessary.
