Re: Problem in clvmd/dlm_recoverd

Could you please share the parameters you tuned, and perhaps a brief explanation of your thinking?  I have hideously slow backups, too, and haven't been successful in improving it through tuning.

We haven't been able to catch it quick enough to determine which process is using all CPU.

The other option is that we're just seeing a huge amount of glocks created on the node running backups and all others (webservers) are just hanging whilst trying to access files. I've just done some fairly aggressive tuning of the GFS mounts on all nodes; hopefully this fixes it!

After tuning some GFS parameters yesterday, last night's backup ran without a hitch! :)
