Here is how you need 3X. First, index everything and optimize. Then
delete everything and reindex without any merges.
You have one full-size index containing only deleted docs, one full-
size index containing reindexed docs, and need that much space for a
third index.
Honestly, disk is cheap, and there is no way to make Lucene work
reliably with less disk. 1TB is a few hundred dollars. You have a free
search engine, buy some disk.

151GB or as little as from 183GB to 182GB. Is that size after a
commit close to the size the index would be after an optimize? For
that matter, are there cases where optimization can take more than
2x? I've heard of cases but have not observed them in my system.
I seem to recall a case where it can be 3x, but I don't know that it
has been observed much.
