After discovering this excellent blog post [1], I thought that taking
advantage of users' "default_placement" feature would be a preferable
way to achieve my multi-tenancy requirements (see previous post).
Alas I seem to be hitting a snag. Any attempt to create a bucket with a
user setup with a non-empty default_placement results in a 400 error
thrown back to the client and the following msg in the radosgw logs:
"could not find placement rule placement-user2 within region"
(The pools exist, I reloaded the radosgw service and ran 'radosgw-admin
regionmap update' as suggested in the blog post before running the
client test)
Here's the setup. What am I doing wrong? Any insight is really
appreciated!

What are the best options to setup the Ceph radosgw so it supports
separate/independent "tenants"? What I'm after:
1. Ensure isolation between tenants, ie: no overlap/conflict in bucket
namespace; something separate radosgw "users" doesn't achieve
2. Ability to backup/restore tenants' pools individually
Referring to the docs [1], it seems this could possibly be achieved with
zones; one zone per tenant and leave out synchronization. Seems a little
heavy handed and presumably the overhead is non-negligible.
Is this "supported"? Is there a better way?
I'm running Firefly. I'm also rather new to Ceph so apologies if this is
already covered somewhere; kindly send pointers if so...
Cheers,
Christian
