Description
The current implementation for defining device classes when an OSD is created is by creating the following file:
/var/lib/ceph/osd/<cluster>-<osd-id>/crush_device_class
It would nice to just declare the device class in the JSON that is sent over when creating the OSD instead of using the file.
The ceph-volume implementation is adding support for device class, so this must be addressed before ceph-volume changes.
It would be nice to keep the file name as the key for the JSON, to keep consistency:
{ "crush_device_class": "value" }
