[rrd-users] RRA resize problem

[Ytsejam]

Dear all,

I used the following command to add more RRA to the RRA[2] and RRA[3] of test.rrd files from 600 to 3600:

My Original setings:

rra             5minAve        AVERAGE:0.5:1:600
rra             30minAve        AVERAGE:0.5:6:600
rra             2hrAve          AVERAGE:0.5:24:600
rra             2hrMax          MAX:0.5:24:600
rra             1dayAve         AVERAGE:0.5:288:600
rra             1dayMax         MAX:0.5:288:600

rrdtool resize test.rrd 0 GROW 2280
mv resize.rrd test.rrd
rrdtool resize test.rrd 1 GROW 2280
mv resize.rrd test.rrd
rrdtool resize test.rrd 2 GROW 3000
mv resize.rrd test.rrd
rrdtool resize test.rrd 3 GROW 3000
mv resize.rrd test.rrd

Now becones:

rra             5minAve        AVERAGE:0.5:1:2880
rra             30minAve        AVERAGE:0.5:6:2880
rra             2hrAve          AVERAGE:0.5:24:3600
rra             2hrMax          MAX:0.5:24:3600
rra             1dayAve         AVERAGE:0.5:288:600
rra             1dayMax         MAX:0.5:288:600




it works, and all my archive data is there (600) with 3000 more NA in front of.
( I use rrdtool dump test.rrd > test.xml , and check the archives)

I use cricket to grap the flow chart.
but after resize the RRA[2] RRA[3] , some of my data has lost in images, but still exist in XML 
when I dump the rrd.

For Ex.
my images shows no data before Oct 22 but there do have data since Oct 10 in the dumped XML file.


Does anyone knows why ?
Please help.

Regards,

Yngwie Chou
