rrdtool                                              RDRESIZE(1)



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

SYNOPSIS
     rrdtool resize filename rra-num  GROWSHRINK rows

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

     filename
             the name of the RD you want to alter.

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

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

     SHRINK  used if you want to remove rows from an RA. 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 RAs, is written to the
     file resize.rrd in the current directory.  The original .rrd
     file is not modified.

     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 RA while at the same
     timestamp this data is available in another RA.
