Hi, I'm configuring ceph as the storage for our openstack install. One thing we might want to do in the future is have a second openstack instance (e.g. to test the next release of openstack); we might well want to have this talk to our existing ceph cluster. I could do this by giving each stack a different ceph username, but I think there's no way to keep them apart, since namespaces don't current work at the rbd level? [the docs say currently (i.e. firefly) not supported] Should I just be creating pools for the different stacks, and hoping this doesn't result in too many pgs? I'm not clear on what's best practice, but the more pools I need to create up-front, the more guesswork that's involved in guessing how big to make them...
