I've been thinking for a while that we need another more general command
than Ceph health to more generally inform you about your cluster. IE I
personally don't like having min/max PG warnings in Ceph health (they
can be independently controlled by ceph.conf options but that kind of
approach won't scale). I'd like another command that I can run that
tells me about this kind of thing. Same thing with experimental
features. I don't want ceph health warning me if they've been enabled,
but I do want to know if they've ever been enabled, when, and whether
they are still in effect.

You will have to consider in the real world whoever built the cluster
might not document the dangerous option to let support stuff or
successor aware. Thus any experimental feature considered not safe for
production should be included in a warning message in 'ceph health', and
logs, either log it periodically or log the warning msg upon restart.
Feature-wise, 'ceph health detail' should give you a report over all
important features/options of the cluster as well.

+1.
For Subversion, we utilize SVN_I_LOVE_CORRUPTED_XXX for a few options
that can cause data corruption. -- justin
