Concept behind Ceph OSD weight

Solution Verified - Updated -


  • Concept behind Ceph OSD weight
  • OSDs weight configuration
Currently we are using 3TB hard drives for ceph OSDs and each of this OSDs has weight=1.
What is the general recommendation of weights configuration? 
Does it make sense to configure OSD weight that reflects capacity of the OSD (i.e. weight=4 for 4TB OSDs and weight=3 for 3TB OSDs)?
