[openstack-dev] [tripleo] Rocky Ceph update/upgrade regression risk (semi-FFE)

Hi folks,

i want to raise attention on remaining patches that are needed to 
prevent losing Ceph updates/upgrades in Rocky [1], basically making the 
Ceph upgrade mechanism compatible with config-download. I'd call this a 
semi-FFE, as a few of the patches have characteristics of feature work, 
but at the same time i don't believe we can afford having Ceph 
unupgradable in Rocky, so it has characteristics of a regression bug 
too. I reported a bug [2] and tagged the patches in case we end up 
having to do backports.

Please help with reviews and landing the patches if possible.

It would have been better to focus on this earlier in the cycle, but 
majority of Upgrades squad work is exactly this kind of semi-FFE -- 
nontrivial in terms of effort required, but at the same time it's not 
something we can realistically slip into the next release, because it 
would be a regression. This sort of work tends to steal some of our 
focus in N cycle and direct it towards N-1 release (or even older). 
However, i think we've been gradually catching up with the release cycle 
lately, and increased focus on keeping update/upgrade CI green helps us 
catch breakages before they land and saves some person-hours, so i'm 
hoping the future is bright(er) on this.

Thanks and have a good day,
