Thanks for the review @lmlg there are a few things that I have not completely figured out (mostly sane detachment of disks). And need to implement a storage_updated event handler in charm to update the unit status. Will resolve your comments along with that. Apart from that this logic does two things nicely:

  1. Automatically enrolls OSDs once disks are added to the unit.
  2. Automatically enrolls OSDs with WAL/DB as soon as equal atleast one of each is available to the unit.
  3. Trigger an event to notify charm about remaining wal/db/disk devices. (Charm will react to it by updating the charm status)
