第 14 章 其他内省操作

14.1. 执行单个节点内省

要在 available 节点上执行一个内省操作,请将该节点设置为管理模式,然后执行该内省操作:

(undercloud) $ openstack baremetal node manage [NODE UUID]
(undercloud) $ openstack overcloud node introspect [NODE UUID] --provide

内省完成后,节点会变为 available 状态。

14.2. 在初始内省后执行节点内省操作

因为 --provide 选项的原因,所有节点在初始内省后都应进入 available 状态。要在初始内省后对所有节点执行内省操作,请将所有节点设置为 manageable 状态,然后运行批量内省命令

(undercloud) $ for node in $(openstack baremetal node list --fields uuid -f value) ; do openstack baremetal node manage $node ; done
(undercloud) $ openstack overcloud node introspect --all-manageable --provide

内省完成后,所有节点都会变为 available 状态。

14.3. 执行网络内省以查看接口信息

网络内省会从网络交换机获取链路层发现协议 (LLDP) 数据。以下命令可显示某个节点上所有接口的某个 LLDP 信息子集,或显示某个节点和接口的全部信息。这对故障排除非常有用。director 默认会启用 LLDP 数据收集。

获取节点上的接口列表:

(undercloud) $ openstack baremetal introspection interface list [NODE UUID]

例如:

(undercloud) $ openstack baremetal introspection interface list c89397b7-a326-41a0-907d-79f8b86c7cd9
+-----------+-------------------+------------------------+-------------------+----------------+
| Interface | MAC Address       | Switch Port VLAN IDs   | Switch Chassis ID | Switch Port ID |
+-----------+-------------------+------------------------+-------------------+----------------+
| p2p2      | 00:0a:f7:79:93:19 | [103, 102, 18, 20, 42] | 64:64:9b:31:12:00 | 510            |
| p2p1      | 00:0a:f7:79:93:18 | [101]                  | 64:64:9b:31:12:00 | 507            |
| em1       | c8:1f:66:c7:e8:2f | [162]                  | 08:81:f4:a6:b3:80 | 515            |
| em2       | c8:1f:66:c7:e8:30 | [182, 183]             | 08:81:f4:a6:b3:80 | 559            |
+-----------+-------------------+------------------------+-------------------+----------------+

查看接口数据和交换机端口信息:

(undercloud) $ openstack baremetal introspection interface show [NODE UUID] [INTERFACE]

例如:

(undercloud) $ openstack baremetal introspection interface show c89397b7-a326-41a0-907d-79f8b86c7cd9 p2p1
+--------------------------------------+------------------------------------------------------------------------------------------------------------------------+

获取硬件内省详细信息

Bare Metal 服务的硬件检查额外功能 (inspection_extras) 会默认启用,以获取硬件详细信息。您可以使用这些硬件详细信息来配置 overcloud。如需了解有关 undercloud.conf 文件中的 inspection_extras 参数的详细信息,请参阅 Configuring the Director

例如,numa_topology 收集程序就是这些硬件检查额外功能的一部分,包括每个 NUMA 节点的以下信息:

  • RAM(单位为 KB)
  • 物理 CPU 内核数和同级线程数
  • 和 NUMA 节点关联的 NIC

使用 openstack baremetal introspection data save _UUID_ | jq .numa_topology 命令并提供裸机节点的 UUID 以获取这些信息。

以下示例显示获取的裸机节点 NUMA 信息:

    {
