I’ve seen similar. Have been wondering if it would be possible to either setup a LoadBalancer or something like “keeepalived” to provide a “VIP” which could move between nodes to support the dashboard (and prometheus, Grafana, etc). I do see notes about HA Proxy in the docs, but haven’t gotten to trying that setup: https://docs.ceph.com/en/quincy/mgr/dashboard/#haproxy-example-configuration In my opinion, a VIP for the dashboard (etc.) could and maybe should be and out of the box config. > On Aug 19, 2024, at 8:23 AM, Tim Holloway <timh@xxxxxxxxxxxxx> wrote: > > Although I'm seeing this in Pacific, it appears to be a perennial issue > with no well-documented solution.
