Sure, the db device has a size of 22.5G, the primary deice has 100G.
Here’s the complete ceph osd df output of one of the OSDs experiencing this
issue:

Hi Daniel,
I had the exact same issue in a (virtual) Luminous cluster without
much data in it. The root cause was that my OSDs were too small (10 GB
only) and the rocksDB also grew until manual compaction. I had
configured the small OSDs intentionally because it was never supposed
to
osd df is misleading when using external DB devices, they are always
counted as 100% full there
