[rrd-users] DS always UNKN. Why?

[Victor Sudakov]

Hello.

I create an rrd for disk usage monitoring:

rrdtool create disk.rrd -s 300 \
        DS:a:GAUGE:600:0:992239 \
        DS:h:GAUGE:600:0:9924475 \
        DS:e:GAUGE:600:0:992239 \
        DS:g:GAUGE:600:0:992239 \
        DS:d:GAUGE:600:0:24772575 \
        RRA:AVERAGE:0.5:1:17280

and then feed it every 5 minutes with the following data:
rrdupdate $RRD/disk.rrd N:260684:1904012:440722:10644:13446247

Why is the DS always UNKN like below? Is this normal behaviour?

Thanks a lot for any input.
