I have a single database on Exchange 2013 which says content index state is disabled, a 5 node DAG which this database has copies of 2 of the 5 servers (by design). Anyway, this is the only database which seems to have content index issues. I have already tried the "stop search and search controller service, and delete "guid" folder and start services thing". The GUID folder is never recreated and index state says disabled in get-mailboxdatabasecopystatus.
Again, all other DB's content index state is "healthy", just this one DB. I can find no documentation where a state of "disabled" is referenced online. Any ideas?
