Re: [ceph-users] Upgrade from Hammer LTS to Infernalis or wait for Jewel LTS?
Here is the roadmap http://docs.ceph.com/docs/master/releases/ EOL is estimated. Or this is what i think of estimated retirement. We are already running hammer. No issues here, except for cahce tier pool with the promotion bug. Don't think the fix was backported to hammer as the time of writing, although it might. Didn't test it again. Are there stability issues with infernalis. As i know thw difference between a LTS and a non-LTS release is that LTS has a longer life span and fixes will be backported so no need for upgrading to the next release to ger the patches. I thought Infernalis should be as stable as Hammer because is an intermediarry release between LTS and not cutting-edge or nightly release. So in your expirience no problem encountered in upgrading from hammer to infernalis as i understand right?

I don't know where you got this information but it seems wrong. From previous history the last 2 LTS versions are supported (currently Firefly and Hammer). That would mean that Hammer should be supported until the L version is released. Infernalis should be supported until the release of Jewel. > If i follow the upgrade procedure there should not be any problems, right? So far we've upgraded every version without issues.

Usually you can upgrade LTS -> LTS, so you should be able to go from Hammer to Jewel. The same should be true to Infernalis. However minimum versions may apply (like you need at least version 0.94.4 to upgrade to infernalis). > > Also what is the correct order of upgrading? Mons first then OSDs?

If it was me, depending on what you value most: if you prefer stability and a conservative approach I'd install Hammer. If you prefer features and performance I'd install Infernalis. As an example all major players (like Redhat, Fujitsu, Suse, etc) use only the LTS versions for their distros. > > Thank you. > > > ___ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

Hi, i was unable to find any time table of EOL's of the different versions. Can you please tell me where your informations come from ( EOL/Release dates, LTS's )? Wiki » Planning » @tracker.ceph.com did not really help Roadmap did not help too.
