It needs as much space as the segments it's merging, so if you have 2 x
10GB segments then you'd want at least 20GB free.

What is the minimum storage space Elasticsearch nodes should have to
ensure smooth merging of segments accounting for index optimize calls. From
my understanding, lucene needs 3X index size space [1] especially during
forced merges. Our use case is not memory bound. Does that mean I should
plan capacity based on only 1/3 total disk space?[1] -
