My comment there

"This issue appears to be documented here: https://docs.ceph.com/en/latest/releases/nautilus/#instructions

Complete the upgrade by disallowing pre-Nautilus OSDs and enabling all new Nautilus-only functionality:

# ceph osd require-osd-release nautilus
Important This step is mandatory. Failure to execute this step will make it impossible for OSDs to communicate after msgrv2 is enabled."
