Hi Folks, I'm trying to use the --data-dir argument of cephadm when bootstrapping a Storage Cluster. It looks like exactly what I need, where my use case is that I want to data files onto a persistent disk, such that I can below away my VMs while retaining the files. Everything looks good and the bootstrap command completes. For reference I am running this command: "sudo cephadm --image "ceph/squid:v19.1.0" --docker --data-dir /cephconfig/var/lib/ceph bootstrap --mon-ip 10.235.22.23 --ssh-user qs-admin --ssh-private-key /home/qs-admin/.ssh/id_rsa --ssh-public-key /home/qs-admin/.ssh/id_rsa.pub --output-dir /cephconfig/etc/ceph --skip-dashboard --skip-monitoring-stack --skip-pull --config my.conf" However, when I then try to continue with the deployment of my Storage Cluster, I find that I can't authenticate with the monitors. I run the suggested command to drop into a cephadm shell which then can't speak to the Storage Cluster. For example: $ ceph -s 2024-08-12T10:47:07.862+0000 7f998e59c640 -1 monclient(hunting): handle_auth_bad_method server allowed_methods [2] but i only support [2,1] [errno 13] RADOS permission denied (error connecting to the cluster) In the MON logs at the same time I can see: "cephx server client.admin: unexpected key: req.key=2c62e1471f111d12 expected_key=d18ce06d18f116b4" In the systemd unit files created I see: ... ExecStart=/bin/bash /var/lib/ceph/64415fba-58b0-11ef-9d27-005056014e4f/%i/unit.run ExecStop=-/bin/bash -c 'bash /var/lib/ceph/64415fba-58b0-11ef-9d27-005056014e4f/%i/unit.stop' ExecStopPost=-/bin/bash /var/lib/ceph/64415fba-58b0-11ef-9d27-005056014e4f/%i/unit.poststop ... Which does not contain my data directory. Looking at the source template it appears that it should: ceph/src/cephadm/cephadmlib/templates/ceph.service.j2 at 616fbc1b181ce15e49281553b35ca215d2aa1053 · ceph/ceph (github.com)<https://github.com/ceph/ceph/blob/616fbc1b181ce15e49281553b35ca215d2aa1053/src/cephadm/cephadmlib/templates/ceph.service.j2#L22> Manually modifying the unit file, reloading systemd and restarting the mon makes the authentication issue go away, although cephadm seems to be periodically rewriting my file and undoing the changes. Is there a templating bug in here? I note that there are no other variables being templated from the ctx in this jinja2 template so it seems likely it is broken.
