No, if we get things right it won't. ALUA already got rid of most of the parameter people would have to set under normal conditions, and I plan to make sure the NVMe equivalent will do it for all parameters. I am active in the NVMe working group and will do my best to get there. There's a few others folks here that are more or less active there as well (Keith, Martin, Jens for example), so I think we have a chance. That beeing said Keith is right that we'll always have odd setups where we need to overrid things, and we will have to provide tunables for that. It's no different from any other kernel subsystem in that.
