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. -- ing.
