       The rreessiizzee function is used to modify the number of rows
       in an RRRRAA.

       _f_i_l_e_n_a_m_e
               the name of the RRRRDD you want to alter.

       _r_r_a_-_n_u_m the RRRRAA you want to alter. You can find the number
               using rrrrddttooooll iinnffoo.

       GGRROOWW    used if you want to add extra rows to an RRA. The
               extra rows will be inserted as the rows that are
               oldest.

       SSHHRRIINNKK  used if you want to remove rows from an RRA. The
               rows that will be removed are the oldest rows.

       _r_o_w_s    the number of rows you want to add or remove.

NNOOTTEESS
       The new .rrd file, with the modified RRAs, is written to
       the file rreessiizzee..rrrrdd in the current directory.  TThhee oorriiggii--

       It is possible to abuse this tool and get strange results
       by first removing some rows and then reinserting the same
       amount (effectively clearing them to be Unknown). You may
       thus end up with unknown data in one RRA while at the same
       timestamp this data is available in another RRA.
