Our corresponding RHCS downstream release of CephFS will be labeled "Tech Preview" which means its unsupported, but we believe that it's stable enough for experimentation. When we do release Cephfs as "production ready" that means we've done even more exhaustive testing and that this is a supported downstream product.
Since our downstream follows our upstream releases, we try to use the same terminology both up and downstream so that folks can better understand how to assess individual releases.
I hope that helps,
Brett

Hi Brett,
aside from the question if what Brian experience has anything to do with
code stability:
since this is new for me, that there is a difference between "stable"
and "production ready" i would be happy if you could tell me how the
table looks like.
One of the team was joking something like:
"stable" > "really stable" > "rock stable" > "pre-production ready" >
"production ready on your own risk" > "production ready, but can still
go boom" > "production ready, but still kinda wonky" > "EOL"
I did not check the past major releases in deep, but i think i never saw
something "bigger" but "stable" as the word to point out, that the code
is ready for usage, where you dont need to expect something too much
evil to happen.. alias "production ready".
So any clearification if this code is now stable, or not, and if yes,
what's the exact difference between "stable" and "production ready", is
very welcome.
Thank you !
