Description John Spray 2017-06-26 09:38:33 UTC

Enable removing and replacing a disk while retaining the OSD ID:
 * To minimize data movement
 * For admin convenience to retain mapping of OSD ID to slot/server

This will apply to both failures and bluestore upgrades.

See http://docs.ceph.com/docs/master/rados/operations/add-or-rm-osds/#replacing-an-osd for the new disk replacement process.

@Ken H, can we please get the official doc based on the link shared by Josh? It will help us verify the official doc for downstream.

Hi Ken,

A gentle reminder. 

Without an official document, QE will not be able to verify this bug.

Could you please help us?
