So we are running ZCA8.0.2 right now. I want to add additional space to my system for e-mail storage. The problem is I don't have additional space in the current data store. I assume I have two options:

1. Down Zimbra and change datastores
2. Add an additional disk from a different data store (if doable).

Option 2 is what I am unsure of. I'm not sure if adding a new disk from a different data store will cause any issues or if it will just look like another disk to ZCA. Has anyone done this? Have any recommendations?
