I did the process a few weeks ago and ended up writing a runbook and a script. I have anonymised and share it fwiw.
https://github.com/arodrime/cassandra-tools/tree/master/remove_disk It is basic bash. I tried to have the shortest down time possible, making this a bit more complex, but it allows you to do a lot in parallel and just do a fast operation sequentially, reducing overall operation time. This worked fine for me, yet I might have make some errors while making it configurable though variables. Be sure to be around if you decide to run this. Also I automated this more by using knife (Chef), I hate to repeat ops, this is something you might want to consider. Hope this is useful, C*heers, ----------------- Alain Rodriguez France The Last Pickle http://www.thelastpickle.com 2016-02-18 8:28 GMT+01:00 Anishek Agarwal <anis...@gmail.com>: > Hey Branton, > > Please do let us know if you face any problems doing this. > > Thanks > anishek > > On Thu, Feb 18, 2016 at 3:33 AM, Branton Davis <branton.da...@spanning.com > > wrote: > >> We're about to do the same thing.
