Just checking here: are your sure all PGs have been scrubbed while
running Luminous? As the release notes [1] mention this:

"If you are unsure whether or not your Luminous cluster has completed a
full scrub of all PGs, you can check your clusters state by running:

# ceph osd dump | grep ^flags

In order to be able to proceed to Nautilus, your OSD map must include
the recovery_deletes and purged_snapdirs flags."

P.s. I expect most users upgrade to Mimic first, then go to Nautilus.
It might be a better tested upgrade path ...
