It would be nice if we could somehow restrict recovery when an OSD is full, to prevent sequential OSD failures as degraded PGs get replicated onto nodes, fill them, and cause crashes. We can certainly (as an option) prevent the monitor from marking OSDs out whenever the full list is non-empty, but we should think about if there are other mitigating actions we can take.
