Luminous missing osd_backfill_full_ratio

Hi All

I feel like this is going to be a silly query with a hopefully simple answer. I don't seem to have the osd_backfill_full_ratio config option on my OSDs and can't inject it. This a Lumimous 12.2.1 cluster that was upgraded from Jewel.

I added an OSD to the cluster and woke up the next day to find the OSD had hit OSD_FULL. I'm pretty sure the reason it filled up was because the new host was weighted too high (I initially add two OSDs but decided to only backfill one at a time). The thing that surprised me was why a backfill full ratio didn't kick in to prevent this from happening.

One potentially key piece of info is I haven't run the "ceph osd require-osd-release luminous" command yet (I wasn't sure what impact this would have so was waiting for a window with quiet client I/O).

ceph osd dump is showing zero for all full ratios:

# ceph osd dump | grep full_ratio
full_ratio 0
backfillfull_ratio 0
nearfull_ratio 0

Do I simply need to run ceph osd set -backfillfull-ratio? Or am I missing something here. I don't understand why I don't have a default backfill_full ratio on this cluster.

Thanks,
