Hi Ernesto, thanks for pointing me in the right direction. I have also found a bug report for the issue: https://tracker.ceph.com/issues/52002 But maybe I'm misunderstanding this whole network setup. Let's say I'm starting to get confused. For example: I have started a very small deployment of a 3 node (4 nodes if you include the cephadm bootstrap node) cluster. I wanted to do this by best practice, and so I created a bond (XOR) for my 10G nics and a VLAN for public (192.168.30.0/24) and one for cluster (192.168.41.0/24). I would like to add additional networks (VLANs) later on for varios service e.g. ISCSI etc. The hosts FQDN are not pointing to 192.168.30.x but to another network where all our hosts reside that are deployed via kickstart. Do I have to ensure that the ceph hosts FQDN points to the 192.168.30 network or is this just for conveniance? I don't mind using the IP of the active mgr to visit the dashboard, but I guess this kind of breaks the idea of having redundancy in case the active mgr fails. I would then have to check who is the active mgr and use it's 192.168.30.x ip adress. Best Regards, Oliver Am 31.

The dashboard was accessible before the upgrade. I googled and found a command to change the listening IP for the dashboard, but I wonder why the upgrade should have changed this? https://people.redhat.com/bhubbard/nature/default/mgr/dashboard/ ceph mgr services { "dashboard": "https://192.168.30.198:8443/";, "prometheus": "http://192.168.30.198:9283/"; } Just for testing I change the IP of the dashboard and now I can access it and log in but then there is no data, no menu display. I assume this is because prometheus IP also needs to be changed? But before I do this, I would like to understand why this was changed during the upgrade.
