Exchange 2013 Content Indexes filling up drives

I have an issue with my Exchange 2013 on 2012R2. The Content index files \ms\%default folder are consuming a large amount of space. We have a DAG with 3 databases.

DB1 - Size: 294GB, Index files are 140GB.
DB2 - Size: 29.53GB, Index files are 2.95GB.
DB3 - Size 128GB, Index files are 43.23.

With some searching I found that the DB1, and DB2 index folders seem to be a normal size which is 10% to 20%  ish of the size of the db. However, DB1 is closer to 50%. I have attempted a restart and update of the servers in the DAG, they seem to be growing faster than I can give disk space.

Hi Brandon,

What are the status of the index?

When you run Get-MailboxDatabaseCopyStatus *

It is healthy status?

You can try to rebuild the index.

I have not attempted to rebuild the index I have never attempted this on a dag. Is there a TechNet article for reference on doing this on a dag a quick search didn't really give me any good results.

They all look health, sorry missed a database in my earlier post.

Has anyone on here ever tried to re index a passive copy of a DB then move the active copy and reseed the indexes to the other DAG members?
