There's of course a performance impact due to the pressure on the OS, but it didn't caused any lock or performance collapse. Of course, now that we had some production time behind us, we can afford scaling up and separating storage and compute concerns and will do, but only to be clean and allow each concern of the cluster to scale independently. For instance, I won't hesitate to add drives to compute hosts, should a massive increase in storage capacity demand come. -------------- next part -------------- A non-text attachment was scrubbed...
