[ceph-users] Determine effective min_alloc_size for a specific OSD

Hi all, I’ve read from this mail list that too high bluestore_min_alloc_size will result in too much space wasted if I have many small objects. But too low bluestore_min_alloc_size will reduce performance. I’ve also read that this config can’t be changed after OSD creation. Now I want to tune this config myself. I change bluestore_min_alloc_size_hdd from default 64k to 32k, then deployed some more OSDs with cephadm. I assume old OSD will continue to use the old setting, and new OSDs will use the new setting. But how can I verify that? To be specific, how can I query the effective min_alloc_size for a specific OSD? I’ve tried to use “ceph daemon osd.X ...” but cannot find the appropriate command. I also searched the OSD logs. Thanks.
