RRD graph not showing up

[szop]

Hey,

I've run into a new problem. I am not able to show up the RRD graph for our second WAN connection. System Logs produce following errors:

php: /status_rrd_graph_img.php: Failed to create graph with error code 1, the error is: ERROR: No DS called 'inpass6' in '/var/db/rrd/opt1-traffic.rrd'/usr/bin/nice -n20 /usr/local/bin/rrdtool graph /tmp/opt1-traffic.rrd-4year.png –start 1228643708 --end 1355133308 --vertical-label "bits/sec" --color SHADEA#eeeeee --color SHADEB#eeeeee --title "hostname - WAN2 :: Traffic - 4 years - 1 day average" --height 200 --width 620 DEF:opt1-in_bytes_pass=/var/db/rrd/opt1-traffic.rrd:inpass:AVERAGE DEF:opt1-out_bytes_pass=/var/db/rrd/opt1-traffic.rrd:outpass:AVERAGE DEF:opt1-in_bytes_block=/var/db/rrd/opt1-traffic.rrd:inblock:AVERAGE DEF:opt1-out_bytes_block=/var/db/rrd/opt1-traffic.rrd:outblock:AVERAGE DEF:opt1-in6_bytes_pass=/var/db/rrd/opt1-traffic.rrd:inpass6:AVERAGE DEF:opt1-out6_bytes_pass=/var/db/rrd/opt1-traffic.rrd:outpass6:AVERAGE DEF:opt1-in6_bytes_block=/var/db/rrd/opt1-traffic.rrd:inblock6:AVERAGE DEF:opt1-out6_bytes_block=/var/db/rrd/opt1-traffic.rrd:outblock6:AVERAGE CDEF:"opt1-in_b

and a few similar one. Any ideas what went wrong and how to solve this?
