I’m not sure where the doubts about old hardware and pg splits come
from. We observed the opposite of what you seem to fear (increasing
memory usage) after a pg split on a customer’s cluster last year.
According to their Prometheus data the memory usage dropped after the
split had finished.

Indeed. Assuming that your failure domain is host, that shouldn’t be a factor
in stranded capacity. We mostly see that happen with say a rack failure domain
cluster with 3 racks and replicated pools, or with your 6,2 pool 6 racks.
Having failure domains > replicatio
I have a single user producing lots of small files (currently about 4.7M
with a mean size of 3 MB). The total number of files is about 7M.
About the occupancy: in 1.8 TiB disks I see the PG count ranging from 27
(-> 38% occupancy) to 20 (-> 27% occupancy) at the same OSD weight
(1.819). I gues

Hi Anthony, thanks for your insights. I actually used df -h from the

Remember that `ceph df` takes into account the full ratio reserved space, and
the headroom between that threshold and the most-full OSD.
Run `ceph osd df` and look at the PGs and VAR columns
