红帽全球峰会1.9.3. 完成 Red Hat Ceph Storage RBD 迁移的先决条件
在开始 Red Hat Ceph Storage Rados 块设备(RBD)迁移前，请完成以下先决条件。
-
目标 CephStorage 或 ComputeHCI 节点都配置为具有
storage和storage_mgmt网络。这可确保使用来自同一节点的 Red Hat Ceph Storage 公共和集群网络。从 Red Hat OpenStack Platform 17.1 及之后的版本，您不必运行堆栈更新。 -
NFS Ganesha 从 director Operator 部署迁移到
cephadm。如需更多信息，请参阅创建 NFS Ganesha 集群。 - Ceph 元数据服务器、监控堆栈、Ceph 对象网关以及 Controller 节点上部署的任何其他守护进程。
- 守护进程分布遵循 Red Hat Ceph Storage 中描述的卡性约束：支持的配置。
-
Red Hat Ceph Storage 集群处于健康状态，
ceph -s命令返回HEALTH_OK。 在裸机节点上运行
os-net-config并配置额外网络：如果目标节点是
CephStorage，请确保在CephStorage节点的裸机文件中定义了网络，例如/home/stack/composable_roles/network/baremetal_deployment.yaml：- name: CephStorage count: 2 instances: - hostname: oc0-ceph-0 name: oc0-ceph-0 - hostname: oc0-ceph-1 name: oc0-ceph-1 defaults: networks: - network: ctlplane vif: true - network: storage_cloud_0 subnet: storage_cloud_0_subnet - network: storage_mgmt_cloud_0 subnet: storage_mgmt_cloud_0_subnet network_config: template: templates/single_nic_vlans/single_nic_vlans_storage.j2添加缺少的网络：
$ openstack overcloud node provision \ -o overcloud-baremetal-deployed-0.yaml --stack overcloud-0 \ /--network-config -y --concurrency 2 /home/stack/metalsmith-0.yaml验证存储网络是否在目标节点上配置：
(undercloud) [stack@undercloud ~]$ ssh heat-admin@192.168.24.14 ip -o -4 a 1: lo inet 127.0.0.1/8 scope host lo\ valid_lft forever preferred_lft forever 5: br-storage inet 192.168.24.14/24 brd 192.168.24.255 scope global br-storage\ valid_lft forever preferred_lft forever 6: vlan1 inet 192.168.24.14/24 brd 192.168.24.255 scope global vlan1\ valid_lft forever preferred_lft forever 7: vlan11 inet 172.16.11.172/24 brd 172.16.11.255 scope global vlan11\ valid_lft forever preferred_lft forever 8: vlan12 inet 172.16.12.46/24 brd 172.16.12.255 scope global vlan12\ valid_lft forever preferred_lft forever
