I guess I left out in my examples, where I tried rbd_cache as well, and failed
# rbd config global set rbd_cache false
rbd: invalid config entity: rbd_cache (must be global, client or client.<id>)
So, while i am happy to file a documentation pull request.. I still need to find the
specific command line that actually *works*, for the "rbd config" variant, etc.

Huhhh...
Its unfortunate that every google search i did for turning off rbd cache, specified
"put it in the [client] section".
Doh.
Maybe this would make a good candidate to update the ceph rbd docs?
As an open source project, I highly encourage you to give back in any
way you can [1].
Speaking of which.. what is the *exact* syntax for
that command please?
None of the below work:
rbd config global set rbd_cache false
rbd config global set rbd cache false
rbd config global set conf_rbd_cache false
rbd config global set rbd cache false
rbd config global set global cache false
and the error messages are not helpful. for example,
# rbd config global set cache false
rbd: invalid config entity: cache (must be global, client or client.<id>)
??? I already specified global??
... because a global configuration override can apply to all entities,
to all clients, or to specific clients (hence the examples for the
entity parameter).
but then
# rbd config global set global cache false
rbd: not rbd option: cache
... the configuration option is "rbd_cache" as documented here [2].
