after 1 form 3 nodes update, ceph showed:
all OSDs are running reef or later but require_osd_release < reef
and second node refuse to upgrade.
Checking Ceph health...
Ceph health not OK.
After checking:
ceph versions
and set:
ceph osd require-osd-release reef
Upgrade go smoothly.

I am planning on updating our system this weekend. We have 6 nodes, 2 of which were management nodes that have been in place for 5 years so have been upgraded multiple times and are currently on 4.0.0. The rest of the nodes were installed with 4.0.
I assume I just need to follow step 7 on page six of the upgrade guide at this point. Is there a particular order I should update? Management nodes first and then storage nodes? Our management nodes are also storage nodes. I just don't want to run into a surprise this weekend with the update.
Thanks,
Neil
