Comment 14 for bug 1267937

There's two more things we can do:

1) add a note in documentation that although Fuel allows to combine multiple roles on the same node, it is recommended to use dedicated OSD nodes in production for better reliability -- that's why there's a docs tag on this bug.

2) add ceph-mon as a standalone role (trivial to do once granular deployment is implemented) to separate failure domains of Ceph monitor and OpenStack controller components -- should be done separately under the blueprint I've just created:
