Hi Gregory, once running ceph online, will ceph change the weight dynamically (if not set properly) or it can only be changed by the user through command line or it cannot be changed online?

My understanding is they are a statistical distribution number. My current setup has 3TB hard drives and they all have the default weight of 1. I was thinking that if I mixed in 4TB hard drives in the future it would only put 3TB of data on them. I thought if I changed the weight to 3 for the 3TB hard drives and 4 for the 4TB hard drives it would correctly use the larger storage disks.
