In addition to the question from Andy, did you remember to add a host 
specific wildcard DISK monitor?

I ran into a similar situation, back when I first started out and was 
told that once you've added any host specific DISK monitors, they 
override all DEFAULT disk monitor settings. As a result, you have to 
follow them up with a host specific wildcard entry, a la:

    DISK   /disk/data 96 98
    DISK   * 90 95
