Not sure if this is intended.
After deleting an OSD with `--replace` flag and create new OSD on it, OSD's WEIGHT is 0.

This is certainly not intended.. I'll investigate

The initial weight is never restored after `draining` the OSDs.
We can save the initial weight/reweight and reset it after the osd is empty and has a `destroyed` flag assigned. This will prevent the OSD from receiving new PGs
