============ Ceph Upgrade ============ This guide documents steps showing Ceph version upgrade. The main goal of this document is to demostrate Ceph chart update without downtime for OSH components. Test Scenario: ============== Upgrade Ceph component version from ``12.2.4`` to ``12.2.5`` without downtime to OSH components. Setup: ====== - 3 Node (VM based) env. - Followed OSH multinode guide steps to setup nodes and install K8s cluster - Followed OSH multinode guide steps upto Ceph install Plan: ===== 1) Install Ceph charts (12.2.4) by updating Docker images in overrides. 2) Install OSH components as per OSH multinode guide. 3) Upgrade Ceph charts to version 12.2.5 by updating docker images in overrides. Docker Images: ============== 1) Ceph Luminous point release images for Ceph components .. code-block:: console Ceph 12.2.4: ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64 Ceph 12.2.5: ceph/daemon:master-a8d20ed-luminous-ubuntu-16.04-x86_64 2) Ceph RBD provisioner docker images. .. code-block:: console quay.io/external_storage/rbd-provisioner:v0.1.0 quay.io/external_storage/rbd-provisioner:v0.1.1 3) Ceph Cephfs provisioner docker images. .. code-block:: console quay.io/external_storage/cephfs-provisioner:v0.1.1 quay.io/external_storage/cephfs-provisioner:v0.1.2 Steps: ====== .. note:: Follow all steps from OSH multinode guide with below changes. 1) Install Ceph charts (version 12.2.4) Update ceph install script ``./tools/deployment/multinode/030-ceph.sh`` to add ``images:`` section in overrides as shown below. .. note:: OSD count is set to 3 based on env setup. .. note:: Following is a partial part from script to show changes. .. code-block:: yaml tee /tmp/ceph.yaml << EOF ... network: public: ${CEPH_PUBLIC_NETWORK} cluster: ${CEPH_CLUSTER_NETWORK} images: tags: ceph_bootstrap: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_config_helper: 'docker.io/openstackhelm/ceph-config-helper:latest-ubuntu_focal' ceph_rbd_pool: 'docker.io/openstackhelm/ceph-config-helper:latest-ubuntu_focal' ceph_mon_check: 'docker.io/openstackhelm/ceph-config-helper:latest-ubuntu_focal' ceph_mon: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_osd: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_mds: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_mgr: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_rgw: 'docker.io/ceph/daemon:master-0351083-luminous-ubuntu-16.04-x86_64' ceph_cephfs_provisioner: 'quay.io/external_storage/cephfs-provisioner:v0.1.1' ceph_rbd_provisioner: 'quay.io/external_storage/rbd-provisioner:v0.1.0' conf: ceph: global: fsid: ${CEPH_FS_ID} rgw_ks: enabled: true pool: crush: tunables: ${CRUSH_TUNABLES} target: # NOTE(portdirect): 5 nodes, with one osd per node osd: 5 pg_per_osd: 100 ...
