Hi Jakub,
No, my setup seems to be the same as yours. Our system is mainly for archiving loads of data. This data has to be stored forever and allow reads, albeit seldom considering the number of objects we will store vs the number of objects
that ever will be requested.
It just really seems odd that the metadata surrounding the 25M objects is so high.
We have 144 osds on 9 storage nodes. Perhaps it makes perfect sense but I’d like to know why we are seeing what we are and how it all adds up.
Thanks!

Hi Dan,
Did you configure block.wal/block.db as separate devices/partition (osd_scenario: non-collocated or lvm for clusters installed using ceph-ansbile playbooks )?
I run Ceph version 13.2.1 with non-collocated data.db and have the same situation - the sum of block.db partitions' size is displayed as RAW USED in ceph df.Perhaps it is not the case for collocated block.db/wal.

_______________________________________________I get that, but isn’t 4TiB to track 2.45M objects excessive? These numbers seem very high to me.

4.65TiB includes size of wal and db partitions too.
