NAME 
rrdresize - alters the size of an RRA and creates a 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 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
RRA while at the same timestamp this data is available in another RRA.
