That's probably the best way to do it. Like I said, there was also a
bug here that I think is fixed for Hammer but that might not have been
backported to Giant. Unfortunately I don't remember the right keywords
as I wasn't involved in the fix.
I'd hope that the complete shutdown scenario would get some more testing in the future... I know that Ceph is targeted more at "enterprise" situations where things like generators and properly sized battery backups aren't extravagant luxuries, but there are probably a lot of clusters out there that will get shut down completely, planned or unplanned.
