we looked at the number of PGs for that pool, and

1 for the rgw.data and rgw.log pools, and "osd pool autoscale-status"
doesn't return anything, so it looks like that hasn't been working.
If you are in this situation, have a look at the crush rules of your
pools. If the cluster has multiple device classes (hdd, ssd) then all
pools need to use just one device class each.
The autoscaler currently does not work when one pool uses just one
device class and another pool uses the default crush rule and therefor
multiple device classes.
