Author of the post here :)
Use the following command to create another ring:
swift-ring-builder /etc/swift/object-1.builder create 15 3 1
Storage Policies are addressed by an index number (see the blog post,
for example storage-policy:0), and these are related to the ring files:
storage-policy:0 -> /etc/swift/object-0.ring.gz
storage-policy:1 -> /etc/swift/object-1.ring.gz
and so on.
Policy 0 is the default one, and if there is no ring file named
"/etc/swift/object-0.ring.gz" Swift tries to use
Let me know if this helps!
