Note: "permalinks" may not be as permanent as we would like,

man mke2fs 
"      -m reserved-blocks-percentage
              Specify  the  percentage  of  the filesystem blocks
              reserved for the super-user.  This  value  defaults
              to 5%.


Are you writing the files as the super-user or as a normal user???
