Overlapping Roots - How to Fix?

[Dave Hall <kdhall@xxxxxxxxxxxxxx>]

Helllo,

I've reviewed some recent posts in this list and also searched Google for
info about autoscale and overlapping roots.  In what I have found I do not
see anything that I can understand regarding how to fix the issue -
probably because I don't deal with Crush on a regular basis.

My particulars:  I have an up-to-date Reef cluster in production with some
EC pools and some replicated pools.  My error messages look like:

pool default.rgw.buckets.data won't scale due to overlapping roots: {-1, -2}
