Hi ,
Thank you for the quick response .. We will try to adapt the script to increase the osd weight.
How to create osd with weight 0 using ceph-volume tool? Or we have to create OSD and later modify the OSD weight to 0.
Thanks,
Muthu

You can add new OSDs with 0 weight and edit below script to increase
the osd weights instead of decreasing.
