Does this persist? In other words, if you just watch it for some time, does the disk usage go back to normal?
Because it's typical that your index size will temporarily spike after the operations you describe as new searchers are warmed up. During that interval, both the old and new searchers are open. Look particularly at your warmup time in the Solr admin page, that should give you an indication of how long it takes your warmup to happen and give you a clue about when you should expect the index sizes to drop again. How often do you optimize on the master and replicate on the slave? Because you may be getting into the runaway warmup problem where a new searcher is opened before the last one is autowarmed and spiraling out of control.
