Gotcha, we are using vnodes - so I'll go sequentially through both datacenters. Unfortunately that's going to take me two months to complete repairs at this rate. :( Thanks again for your help, SL On Mon, Aug 24, 2015 at 5:17 PM, Robert Coli wrote: > On Mon, Aug 24, 2015 at 2:14 PM, Stan Lemon

Rob, Thanks for all the tips. So I do have SSDs and I set the throttle to 0, and have started using the --parallel mode. It's taking me about 2.5 days to complete a node at this point. I do have one other logistical question for you. My tables all have RF2 and I my topology is set to have one rac

Rob, Thanks for the reply. I do have vnodes. I was not aware of the -par flag on the repair command, I was actually referring to have repair run on both nodes A & B at the same time. It sounds like though, that I should probably be using this -par flag but to do it per node sequentially one afte
