I'd like to test how reweighting an OSD will change how the PGs map in the cluster.
I suspect that I'd dump the CRUSH map and PGs in the cluster that I'm interested in then use osdmaptool. I'm not understanding how to use osdmaptool to set the reweight, then query a PG or the entire set of PGs that I'm interested in. I then suspect that if I'm okay with the new map that I could inject it into the cluster instead of having to run reweight on the OSD(s).
This is a Jewel cluster and I'm trying to calculate OSD usage offline, then inject a map that is more distributed instead of doing a reweight, move the PGs which take a long time to just rinse and repeat over and over again.
Thanks,
Robert LeBlanc
