i did a nodetool rebuild on one of the nodes. Datacenter: DC1 ================ Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack *UN 10.123.75.51 10.54 GB 256 16.0% d2f980c1-cf82-4659-95ce-ffa3e50ed7c1 RAC1* UN 10.123.75.53 5.18 GB 256 16.5% bab7739d-c424-42ef-a8f6-2ba82fcdd0b9 RAC1 UN 10.123.75.52 5.51 GB 256 18.3% 70469a76-939b-4b8c-9512-33aedec6fd3e RAC1 Datacenter: DC2 ================ Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN 10.123.75.51 5.3 GB 256 16.1% 106d5001-2d44-4d81-8af8-5cf841a1575e RAC1 UN 10.123.75.52 5.34 GB 256 16.2% c4333d90-476a-4b44-bc23-5fca7ba6a2e7 RAC1 UN 10.123.75.53 5.11 GB 256 16.8% 8154288e-a0fb-45f8-b3fb-6c3d645ba8f3 RAC1
In that node the Load has increased from around 5GB to 10GB. But the tokens remains same (256). My expectation was that it would come down to 1. i will continue to rebuild the remaining nodes. But not sure whether this is helping. On Fri, Jul 4, 2014 at 7:28 PM, Rameez Thonnakkal <ssram...@gmail.com> wrote: > Thanks Mark. > the procedure you shared is useful.
