Re: [Ganglia-general] Ganglia no longer updates certain RRDs

[Vitaly Karasik]

  
 We had couple spikes in our RRDs which I decided to remove 
 using the removespikes script floating around. Script usually 
 works well. This time around by accident I ran the script as 
 root and all the RRDs got chowned to root. We figured what 
 happened, fixed the permissions but Ganglia no longer updates 
 the RRDs. If I completely remove the directory  new RRDs are 
 created and everything works great however all my history is 
 gone. Any way to troubleshoot this ?
 
 I did rrdtool dump on the rrds and data in them looks legit 
 just that the last data point is from 2 hours ago or so.
 
you can use merge-rrd for merging your old and new rrd's.
BTW, did you restart gmetad after fixing permission problem?

Rgds,
