      Thanks. 
        

        Can you recommend any docs for understanding the BlueStore
          on disk format/behavior when there is no separate device for
          the WAL/DB?

            Hi Frank,
            no spillover happens/applies for the main device hence
              data beyond 30G is written to main device as well.
            

            Thanks,
            Igor

              Hi all,

                
                How is the following situation handled with
                  bluestore:
                

                1. You have a 200GB OSD (no separate DB/WAL
                  devices)
                2. The metadata grows past 30G for some reason and
                  wants to create a 300GB level but can't?
                

                Where is the metadata over 30G stored?
