While we had to migrate/change ceph mon ip's in our openstack
deployment, which is stein at the moment, we got hit by the same
problem.
We fixed it also by manually changing all db entries that required an update.
Comment https://bugs.launchpad.net/nova/+bug/1452641/comments/23 helped us a
ton
Please don't set OpenStack bugs to Public Security without some
explanation as to why you believe this to be an exploitable risk which
needs attention from the OpenStack vulnerability managers for
coordinating a possible security advisory. I'm switching this back to a
normal Public bug for now,

We are also experiencing this issue with Stein.
We are deployed using rook-ceph as our ceph deployment and the monitors
IP address will rotate if any of the monitors are down for more than 10
minutes. Which means anytime we do maintenance on a node running one of
rook-ceph's monitors the ip
We have the same issue with Rocky.
One of my SQL wizard colleague helped me with some query, which can change the
block_device_mapping table, and the RBD host/username/ports (if you change the
number of ceph monitors, you'll need it)
Since we have multiple Zones, and our change will only affect
We have also been bitten by this. Apologies if this does not help solve
the bug, but this issue has been floating for quite awhile and the
following may help future cloud operators...
In our case, we trying to re-IP ALL of our Ceph Mons. As Corey
mentioned, this bug report is for *Cinder
We're changed our ceph-monitor ip's and we're running into this issue
unfortunately. It is fixed on the cinder side, but still broken on the
nova side. We could fix it with patch in of Walt (comment #9) but there
must be more users running into this issue unknowingly.

Just a clarification on the process to 'move' ceph-mon units. I added
ceph mons to the cluster, and removed the old ones - in this case it was
a 'juju add-unit' and 'juju remove-unit' but any process to achieve the
same thing would have the same result - the mons are now all on
different

I did some initial testing with the default parameter value for
refresh_conn_info set to True in _get_instance_block_device_info() and
unfortunately an instance with rbd volume attached does not successfully
stop/start after ceph-mon's are moved to new IP addresses.

FWIW, in the cloud we saw this, migrating the (stopped) instance also
updated the connection info - it was just that migrating hundreds of
instances wasn't practical.

Just to summarize my understanding, and perhaps clarify for others, this
bug is focused on stale connection_info for rbd volumes (not rbd
images). rbd images have a related issue during live migration that is
being handled in a separate bug (see comment 12 above).
