OK, so for interventions, I've pushed these configs out: ceph config set mon.* target_max_misplaced_ratio 0.05 > 0.20 ceph config get osd.* osd_max_backfills 1 > 4 ceph config set osd.* osd_recovery_max_active 1 > 4 And also ran injectargs to push the changes to the OSDs hot.

Because I'd like to turn up the rate at which it splits the PG's, but if autoscaler isn't doing it, I'd have no clue what to adjust. Any ideas?
Normal recovery ops I imagine - Bump up the recovery settings, Max Backfills and Recovery Max Active
