In other words, Ceph will complain about not running msgr2, but you should leave it like that until all OSDs are on Nautilus. Then you run: ceph mon enable-msgr2 ceph osd require-osd-release nautilus Ref: https://docs.ceph.com/docs/master/releases/nautilus/ -- Alex Gorbachev Intelligent Systems Services Inc. > > > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx > _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
