In the end if was because I hadn't completed the upgrade with "ceph osd require-osd-release luminous", after setting that I had the default backfill full (0.9 I think) and was able to change it with ceph osd set backfillfull-ratio.
Potential gotcha for a Jewel -> Luminous upgrade if you delay the "...require-osd-release luminous" for whatever reason as it appears to leave you with no backfillfull limit Still having a bit of an issue with new OSDs over filling but will start a new thread for that Cheers, On Thu, Aug 30, 2018 at 10:34 PM David Turner <drakonst...@gmail.com> wrote: > This moved to the PG map in luminous.
