I have a 2 server DAG with 5 DB's. I'm running low on disk space and I've done a lot of cleanup and have had users do a lot of email cleanup but I'm not gaining any space back. From everything I've been reading, it looks like I need to defrag my db's before I will actually see any space gain in the OS. My question is since I have a DAG, I have all of the databases mounted on 1 server (ServerA) and the db's on ServerB are Healthy but not active at the moment. Am I able to run the defrag on the inactive db's without affecting my live system since the db's are actually mounted on ServerA? If so, what is process of taking them offline on ServerB to do the defrag?
Thanks so much,
