Multiple things: 1. We removed all the function/methods/tests that were used to create and manage rook legacy OSDS as well as bringing support to Bluestore OSD only. It also fixes various go-lint issues in the respectives files. 2. use c-v inventory to detect available devices: Now we rely on the 'ceph-volume inventory' command to tell us if a device is available or not. 3. implement raw mode for osd on pvc When an OSD will be bootstrap on a PVC, the new c-v raw mode will be used. It consists of putting block, db and wal under the same device. Here LVM is out of the picture and the raw device is used as is. The implementation is backward compatible so existing OSD on PVC will LVM will continue to operate. Closes: https://github.com/rook/rook/issues/4363 Signed-off-by: Sébastien Han <seb@redhat.com>
