Hi,

1. Is it possible configure use osd_data not as small partition on OSD but
a folder (ex. on root disk)? If yes, how to do that with ceph-disk and any
pros/cons of doing that?
2. Is WAL & DB size calculated based on OSD size or expected throughput
like on journal device of filestore? If no, what is the default value and
pro/cons of adjusting that?
3. Is partition alignment matter on Bluestore, including WAL & DB if using
separate device for them?

Best regards,
