       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innaall  ..rrrrdd  ffiillee  iiss  nnoott

       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.
