- odf get recovery-profile
显示为 OSD 设置的 recovery-profile 值。默认情况下，如果没有使用
odf set recovery-profile命令设置值，则会显示空值。设置值后，会显示适当的值。示例 ：
$ odf get recovery-profile
# high_recovery_ops- ODF 获取健康状况
检查 Ceph 集群的运行状况和常见配置问题。这个命令检查以下内容：
- 至少三个 mon pod 在不同的节点上运行
- mon quorum 和 Ceph 健康详情
- 至少三个 OSD pod 在不同的节点上运行
- 所有 pod 的"Running"状态
- 放置组状态
至少一个 MGR pod 正在运行
示例 ：
$ odf get health Info: Checking if at least three mon pods are running on different nodes rook-ceph-mon-a-7fb76597dc-98pxz Running openshift-storage ip-10-0-69-145.us-west-1.compute.internal rook-ceph-mon-b-885bdc59c-4vvcm Running openshift-storage ip-10-0-64-239.us-west-1.compute.internal rook-ceph-mon-c-5f59bb5dbc-8vvlg Running openshift-storage ip-10-0-30-197.us-west-1.compute.internal Info: Checking mon quorum and ceph health details Info: HEALTH_OK [...]
- ODF get dr-health
在启用了镜像的集群中，从另一个集群获取集群的连接状态。
cephblockpool通过启用了镜像功能查询，如果未找到，则会退出相关日志。示例 ：
$ odf get dr-health Info: fetching the cephblockpools with mirroring enabled Info: found "ocs-storagecluster-cephblockpool" cephblockpool with mirroring enabled Info: running ceph status from peer cluster Info: cluster: id: 9a2e7e55-40e1-4a79-9bfa-c3e4750c6b0f health: HEALTH_OK [...]- ODF 获取 dr-prereq
检查并获取所有先决条件的状态，以便在一对集群中启用灾难恢复。该命令取对等集群名称作为参数，并使用它来比较当前的集群配置与对等集群配置。根据比较结果，会显示先决条件的状态。
Example
$ odf get dr-prereq peer-cluster-1 Info: Submariner is installed. Info: Globalnet is required. Info: Globalnet is enabled. odf get mon-endpoints Displays the mon endpoints $ odf get dr-prereq peer-cluster-1 Info: Submariner is installed. Info: Globalnet is required. Info: Globalnet is enabled.
