Unfortunately, for some reason, one of the files is missing. In that case, it is the .rrd file. So to make the graphs work again, you need to  stop the site, find all the .info files with a missing .rrd file, and to delete them manually: 

OMD[mysite]:~$ for i in $(find ~/var/check_mk/rrd -name *.info); do test -e ${i%info}rrd || echo $i; done
/omd/sites/mysite/var/check_mk/rrd/<HOSTNAME>/PING.info
/omd/sites/mysite/var/check_mk/rrd/<HOSTNAME>/CPU_Utilization_Mgmt_CPU.info
/omd/sites/mysite/var/check_mk/rrd/<HOSTNAME>/CPU_Utilization_Packet_CPU_1.info
/omd/sites/mysite/var/check_mk/rrd/<HOSTNAME>/CPU_Utilization_Packet_CPU_0.info

Now you have a list of files to delete. Please replace echo $i with rm $i in order to delete those files.

After you delete the affected files, you need to start the site so to create the new files are created.
