[rrd-users] how can i rebuild my rrd files ?

[mozatkey]

hi,all:

1. How can I get the creating script if only having xxx.rrd ?
There are a lot of rrd files, i can't get all the creating script for
each one, because they have been modified many times by handle operation.

2.How can I set the HWPREDICT with those old rrd files?
These old rrds files don't set the HWPREDICT, but now i have to use it.

3. Is there any orders like: "show create rrd" and "alter xxx.rrd add
HWPREDICT" in rrdtool , just as what we did in pl/sql?

All the rrd files have running for years, and can not be destroyed.

thanks
