- set osd_memory_target_autotune=true to enable - tuning is periodic (check every 10m by default) - tuned values are reflected by osd_memory_target config options scoped to the host - only make a change if it appears that we will affect at least 1 of the relevant OSDs - attempt to clean out conflicting options. (This is imperfect, since any manner of weirdly-scoped config options could be responsible; we only attempt to clean out one scoped directly to the osd name.)
