Hi MJ,
Here are the links to the script and config file. Modify the config file as you wish, values in config file can be modified while the script execution is in progress. The script can be run from any monitor or data node. We tested and the script works in our cluster. Test it in your lab before using it in production.
Script Name: osd_crush_reweight.py
Config File Name: rebalance_config.ini
Script: https://jpst.it/1gwrk
Config File: https://jpst.it/1gwsh

We recently added a lot of nodes to our ceph clusters. To mitigate lot of problems (we are using tree algorithm) we added an empty node first to the crushmap and then added OSDs with zero weight, made sure the ceph health is OK and then started ramping up each OSD. I created a script to do it dynamically, which will check CPU of the new host with OSDs that
Would you mind sharing this script..?
