Copying Alfredo, as I’m not sure if something changed with respect to ceph-volume in 12.2.2 (when this originally happened) to 12.2.5 (I’m sure plenty did), because I recently had an NVMe drive fail on me unexpectedly (curse you Micron), and had to nuke and redo some SSD OSDs, and it was my first time deploying with ceph-deploy after the ceph-disk deprecation. The new OSD’s appear to report correctly wrt to the rotational status, where the others did not. So that appears to be working correctly, just wanted to provide some positive feedback there. Not sure if there’s an easy way to change those metadata tags on the OSDs, so that I don’t have to inject the args every time I need to reweight. Also feels like journal_rotational wouldn’t be a thing in bluestore?
The fix is in core Ceph (the OSD/BlueStore code), not ceph-volume. :) journal_rotational is still a thing in BlueStore; it represents the combined WAL+DB devices.
