Alex, Is there a reason you don't just join new hardware to the cluster and then remove the old hardware from the cluster? That would seem like the easiest way to accomplish a hardware upgrade.

I've left the system running in production environment for long term testing. I've accumulated about 350GB of data with RF=2. The machines I used for the tests are older and need to be replaced. Because of this I need to export the data to a permanent location. How should I export the data? In order to reduce the storage spac I want to export only the non-replicated data? I mean, just one copy of the data (without the replicas). Is this possible? How? Cheers, Alexandru
