Hi,
I hope you are following this :
http://ceph.com/docs/master/rados/operations/add-or-rm-osds/#removing-osds-manual
After removing the osd successfully run the following command :
# ceph-deploy --overwrite-conf osd create <osd-host>:<device-path>
--zap-disk
It will give you the same osd id for new osd as old one for that disk.
Regards,
Vikhyat

I am fairly new to ceph and so far things are going great. That said,
when I try to replace a failed OSD, I can't seem to get it to use the
same OSD id#. I have gotten it to point which a "ceph osd create" does
use the correct id# but when I try to use ceph-deploy to instantiate
the replacement, I get working osd which uses the next highest number.
My setup is....
18 nodes
12 OSD's each
216 total OSD's
Ceph 0.80.7
ceph-deploy 1.15.22( also tried 1.15.11)
RHEL 6.6
All of the docs I've read say that if what has happened to me does
occurr, then it's likely the original OSD references are not quite
cleared out. So my questions are....
1. How do I track down all traces of the old OSD
2. Can someone point me to a known good set of instructions for using
cep-deploy to replace an OSD using the samel ID?
3. Is using the same ID a deprecated idea?
Thanks
