It is not because user want to skip odd release, it just we usually land major and important feature to even release:) We have several large ceph cluster starting from Firefly Although in practice we only use LTS release but it is not because we bias LTS release, just the timeline is a little bit misleading... Lets use kraken as an example , it is out on late jan , when I deciding whether to upgrade all cluster to kraken, the timeline said Luminous will be out on April, although from the community activity it doesn't looks like it, but in all public presentation we(the community) were releasing the same information. Considering the effort of pre-production test and rolling upgrade usually take half a month, we decide to skip kraken and wait for another 3 month(but actually 8 months). Rethinking about it now, if either 1) community re-adjust the release timeline in Jun, postpone Luminous to August , we will do the upgrade. 2) some important features first ready in Kraken( Multi-mds, Bluestore, EC overwrite), we will also do the upgrade. But both are not true. 2017-09-08 17:20 GMT+08:00 Matthew Vernon <mv3@xxxxxxxxxxxx>: > Hi, > > On 06/09/17 16:23, Sage Weil wrote: > >> Traditionally, we have done a major named "stable" release twice a year, >> and every other such release has been an "LTS" release, with fixes >> backported for 1-2 years. > > We use the ceph version that comes with our distribution (Ubuntu LTS); > those come out every 2 years (though we won't move to a brand-new > distribution until we've done some testing!).
