See image. How and where do i edit the data to remove the bad record of the large data spike (petabytes). I understand that the service pvestatd reports the data but where is it stored and can it be corrected without loosing historic data?error.JPG
 
it's stored as RRD data in /var/lib/rrdcached on each node
