we increased to osd_max_scrubs=5 to clear out a scrubbing backlog; I
wonder if the increased read/write ratio somehow led to an exploding
buffer_anon. Do things stabilize on your side if you temporarily
disable scrubbing?
During the worst periods, we had disabled scrubbing. When we re-enabled,
we had our write-job to mitigate the problems. And currently, scrub load
is low. So I cannot tell, but it is very plausible.
