splunk list of indexes with buckets exceeding the replication or search factor

[raindrop18]

on my indexer cluster I see lists it say "Here is a list of indexes with buckets exceeding the replication or search factor" and has a remove button.
- what are these, I have set my replication factor so where this excessive list came from
- also it's safe to remove them, this automatically can be done or manually need to be clean up and what the effect not doing that.

thanks!!

@raindrop18: excess copies result from peers(indexers) leaving and joining the cluster.
you can remove excess buckets from cluster master via cli or web ui.
follow the splunk doc for further explanation..
https://docs.splunk.com/Documentation/Splunk/7.2.1/Indexer/Removeextrabucketcopies
also take a look at data-rebalancing, cluster master removes excess buckets during data-rebalance..
