Dear Ladies and Gentlemen,

Please would you let me know how I can change the number of data points
in an archive (the size of the RRAs) ?

Is the way to do this

. define a new RRD

. fetch from the old, correcting the value according to the DS type
(adding the last value if COUNTER etc)

. update the new


I have tried this and the results are disappointing - the pdp vals don't 
match. Caveat bugs in processing ...

Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'

from Meditation 17, J Donne.
