[1mDESCRIPTION[0m
       The [1mresize [22mfunction is used to modify the number of rows in an [1mRRA[22m.

       [4mfilename[0m
               the name of the [1mRRD [22myou want to alter.

       [4mrra-num[24m the [1mRRA [22myou want to alter. You can find the number using [1mrrd-[0m
               [1mtool info[22m.

       [1mGROW    [22mused if you want to add extra rows to an RRA. The extra rows
               will be inserted as the rows that are oldest.

       [1mSHRINK  [22mused if you want to remove rows from an RRA. The rows that will
               be removed are the oldest rows.

       [4mrows[24m    the number of rows you want to add or remove.

[1mNOTES[0m
       The new .rrd file, with the modified RRAm, is written to the file
       [1mresize.rrd [22min 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 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.
