I have given up on fixing the “high pg count deviation” on my Ceph cluster. I have a 4TB HDD and a 240GB SSD on one node. The SSD cant hold as many PGs and the HDD do. Maybe i should try to turn the SSD into a cache for the HDD. It looks complicated when i read about it. It is so easy on Storage Spaces direct.
Update: I have set the SSDs as block database and write ahead log for the HDDs. Now only the HDDs are listed and they all have the same PG count.
