Hello there, I was thinking about storing indices files on several disk partitions. Why? Because some indices will be huge and "low risk" (indexing logs) and others won't be that big but will be sensitive. That would allow me to set different alert levels on partition usage, and maybe make things safer for index files? So my questions: 1. Is storing indices on different partitions (on the same physical disk) doable/a good idea? Or could it trigger problems with cluster state? Maybe there's no point at all? 2. How would you achieve it? Symlinks? Thanks! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

It's no problem operationally, although there will probably be little value in it. If it makes your life easier monitoring disk usage, go for it. It won't affect cluster state and probably won't have any effect on performance. That said, operating systems and hdd/ssds are complicated things nowadays and it could dramatically help or hinder either way. It's always best to profile it with a large amount of your data. > 1.
