红帽全球峰会11.3. 将 OSD 添加到 Ceph Storage 节点
此流程演示了如何将 OSD 添加到节点。有关 Ceph OSD 的更多信息，请参阅 Red Hat Ceph Storage Operations 指南中的 Ceph OSD。
流程
请注意，以下 heat 模板将使用三个 OSD 设备部署 Ceph Storage：
parameter_defaults: CephAnsibleDisksConfig: devices: - /dev/sdb - /dev/sdc - /dev/sdd osd_scenario: lvm osd_objectstore: bluestore要添加 OSD，请更新节点磁盘布局，如 第 5.3 节 “映射 Ceph Storage 节点磁盘布局” 所述。在本例中，将
/dev/sde添加到模板中：parameter_defaults: CephAnsibleDisksConfig: devices: - /dev/sdb - /dev/sdc - /dev/sdd - /dev/sde osd_scenario: lvm osd_objectstore: bluestore-
运行
openstack overcloud deploy以更新 overcloud。
注意
在本例中，所有具有 OSD 的主机都有一个新设备，称为 /dev/sde。如果您不希望所有节点具有新设备，请更新 heat 模板。有关如何使用不同 devices 列表定义主机的详情，请参考 第 5.5 节 “覆盖用于忽略 Ceph Storage 节点的参数” 和 第 5.5.1.2 节 “更改 Ceph Storage 节点中的磁盘布局”。
