No idea about ceph/storage, but the cockpit deployment guide was
removed because it's deprecated:
https://bugzilla.redhat.com/show_bug.cgi?id=2020448
We also cleaned up various links to that guide [1], but apparently not
in the blog - no idea how that one is maintained. Sandro? Perhaps this
(how the blog is maintained) should also be mentioned in one of the
top-level md files (README*, CONTRIBUTING.md, not sure).
