>> 4. Revert all your reweights. > >Done You mean the values in the reweight column or the weight column? Because from the commands in this thread I am assuming the weight column. Does this mean that the upmap is handling disk sizes automatically? Currently I am using the balancer (turned off) in crush-compat mode and have a few 8TB disks mixed with 4TB disks.
