If I change the network topology, I have to run repair right before adding a new cluster ?
I know that I should put 2 more nodes, so far, I'm preparing myself to create a new node on a new DC, but on same network (ping really low), so at least I would have a backup server if anything happens, just need to wrap my head around the network topology and understand what I do before starting a new node. 2015-01-22 19:15 GMT+01:00 Flavien Charlon <flavien.char...@gmail.com>: > I don't think you can do nodetool repair on a single node cluster. > > Still, one day or another you'll have to reboot your server, at which > point your cluster will be down.
