I activated autoscaler on all my pools but found this error msg when it came to the
cache_pool.
ceph-mgr.pve22.log.3:2020-05-01 23:59:24.014 7f5120eda700 0 mgr[pg_autoscaler] pg_num
adjustment on cache_pool to 512 failed: (-1, '', 'splits in cache pools must
be followed by scrubs and leave sufficient free space to avoid overfilling. use
--yes-i-really-mean-it to force.')
I ended up clearing the cache pool by limiting it to max 1 object and increasing the
pg_num/pgp_num. Now I expect the scrub to being every 24h automatically.
Should this be included in the docs? Is this a bug of pg_autoscaler ?
BR,
Alex
