Dear list,
we are upgrading our ceph infrastructure from mimic to octopus (please
be kind, we known that we are working with "old" tools, but these ceph
releases are tied to our openstack installation needs) and _*all*_ the
ceph actors (mon/mgr/osd/rgw - no mds as we do not serve filesystem)
were upgraded fine as follow:
# ceph -v
ceph version 15.2.17 (8a82819d84cf884bd39c17e3236e0632ac146dc4)
octopus (stable)
We're using a ubuntu/juju orchestrator for managing ceph (and openstack
too).
It seems all ok, but if I ask a mon to dump the sessions, we get
that_all of them_ are on luminous:
"con_features": 4540138292840890367,
"con_features_hex": "3f01cfb8ffedffff",
"con_features_release": "luminous",
We found this oddity when we tried to unset the "insecure global_id
reclaim" flag and all things got broken, so we had to reactivate the flag.
All ceph network layers are "closed", so we're not so urged to remove
the flag, but we would like to understand if this is a known problem or
an error done by us.
Any hints ?
thanks in advance.
