1. Out the osd
2. Wait for the cluster rebalance to finish
3. Stop the osd

old process. I should also note, by reweighting to 0, when I tried to run "ceph osd out #", it said it was already marked out.
I assume the docs are correct, but just want to make sure since reweighting had been previously recommended.
The new commands just make it more simple. There are many ways to accomplish the same goal, but what the docs describe should work in most scenarios.
