故障排除¶
一旦所有服务都已运行并正确配置，并且节点已使用 Bare Metal 服务注册并处于 available 可用供应状态，Compute 服务应将该节点检测为可用资源并将其暴露给调度器。
注意
存在延迟，Compute 服务识别 Bare Metal 服务资源（包括添加和删除）中的任何更改可能需要最多一分钟（一个周期性任务周期）。
除了查看 nova-compute 日志文件外，您还可以通过查看 Compute hypervisor 列表来查看可用资源。其中报告的资源应与裸机节点属性和 Compute 服务 flavor 匹配。
以下是一些比较 Compute 服务和 Bare Metal 服务中资源的命令示例

维护模式¶
如果您需要将节点从资源池中移除，可以使用维护模式。将节点置于维护模式将阻止 Bare Metal 服务执行与该节点关联的周期性任务。 这也会阻止 Compute 服务通过不将节点暴露给 nova 调度器来在该节点上放置租户实例。 可以使用以下命令将节点置于维护模式。
$ baremetal node maintenance set $NODE_UUID
可以使用可选的 --reason 命令行选项包含维护原因。 这是一个自由文本字段，将在 node show 命令的 maintenance_reason 部分中显示。
$ baremetal node maintenance set $UUID --reason "Need to add ram."
$ baremetal node show $UUID
+------------------------+--------------------------------------+
| Property | Value |
+------------------------+--------------------------------------+
| target_power_state | None |
| extra | {} |
| last_error | None |
| updated_at | 2015-04-27T15:43:58+00:00 |
| maintenance_reason | Need to add ram. |
| ... | ... |
| maintenance | True |
| ... | ... |
+------------------------+--------------------------------------+
要移除维护模式并清除任何 maintenance_reason，请使用以下命令。
$ baremetal node maintenance unset $NODE_UUID
