NAME
       rrdresize - alters the size of an RRA and creates new .rrd
       file

SYNOPSIS
       rrdtool resize filename rra-num  GROW|SHRINK rows

DESCRIPTION
       The resize function is used to modify the number of rows
       in an RRA.

       filename
               the name of the RRD you want to alter.

       rra-num the RRA you want to alter. You can find the number
               using rrdtool info.

       GROW    used if you want to add extra rows to an RRA. The
               extra rows will be inserted as the rows that are
               oldest.

       SHRINK  used if you want to remove rows from an RRA. The
               rows that will be removed are the oldest rows.

       rows    the number of rows you want to add or remove.

NOTES
       The new .rrd file, with the modified RRAs, is written to
       the file resize.rrd in the current directory.  The origi-
       nal .rrd file is not modified.

       It is possible to abuse this tool and get strange results
       by first removing some rows and then reinsert 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.
