During indexing, if the performance of the disk is degraded in the middle and the whole index write is slowed down.
In this case, I want to the use function that ES can solve automatically using the specific option.
I looked for the [Tune of disk usage] document(https://www.elastic.co/guide/en/elasticsearch/reference/5.2/tune-for-disk-usage.html), but this is an option to take the action manually by knowing the phenomenon in advance.
What I want to know is that if this happens when I am not working, the ES will automatically improve disk performance or have the option to reroute the shard of a node with a disk fault
If you know what I want, please share them with me.
Thanks for reading.
