> To setup a SBN we currently format the primary then manually copy the name
> dirs to the SBN. The SBN should do this automatically. Specifically, on NN
> startup, if HA with a shared edits dir is configured and populated, if the
> SBN has empty name dirs it should downloads the image and log from the
> primary (as an optimization it could copy the logs from the shared dir). If
> the other NN is still in standby then it should fail to start as it does
> currently.
