I had followed the steps in the documentation, but it’s likely that something went wrong during those steps. I copied over the mon store instead, as you recommended, and it fixed my problem. Thanks for your help, now I can finally progress with this.

The order of all commands is very important, as well as making sure that permissions are set correctly (ceph.ceph). I have not tried to upgrade this way (I think I would have copied over the old mon store and have ceph upgrade it if necessary). You might still want to try that (stop a nautilus mon, copy over data, start octopus mon). > > > Gr.
