Re: Adding a New Node

Your node shouldn't show up in DC1 in nodetool status from the other nodes, this implies a configuration problem. Sounds like you haven't added the new node to all the existing nodes cassandra-topology.properties file. You don't need to do a rolling restart with PropertyFileSnitch, it should reload

Re: Adding a new node with the double of disk space

I would preferably spin 2 JVMs inside the same hardware (if you double everything) than having to deal with what Jeff stated. Also certain operations are not really found of a large number of vnodes (eg. repair). There was a lot of improvements in the 3.x release cycle, but I do still tend to redu

Re: Adding a new node with the double of disk space

If you really double the hardware in every way, it's PROBABLY reasonable to double num_tokens. It won't be quite the same as doubling all-the-things, because you still have a single JVM, and you'll still have to deal with GC as you're now reading twice as much and generating twice as much garbage,

Re: Adding a new node with the double of disk space

Are you saying if a node had double the hardware capacity in every way it would be a bad idea to up num_tokens? I thought that was the whole idea of that setting though? On Thu, Aug 17, 2017 at 9:52 AM, Carlos Rolo wrote: > No. > > If you would double all the hardware on that node vs the others

Re: Adding a new node with the double of disk space

No. If you would double all the hardware on that node vs the others would still be a bad idea. Keep the cluster uniform vnodes wise. Regards, Carlos Juzarte Rolo Cassandra Consultant / Datastax Certified Architect / Cassandra MVP Pythian - Love your data rolo@pythian | Twitter: @cjrolo | Skype

Re: Adding a New Node With The Same IP of an Old Node

Thanks Nitan! Eventually it was a firewall issue related to the Centos7 node. Once fixed, the rolling restart resolved the issue completely. Thanks again! Shalom Sagges DBA T: +972-74-700-4035

Re: Adding a new node

Thanks for the pointer. I restarted entire cluster and started nodes at the same time. However, I still see the issue. The view is not consistant. Am running 0.7.5. In general, if a node with bad ring view starts first, then I guess the restart also doesnt help as it might be propagating its view
