8.2. 检查 Controller 节点资源问题

根据问题的类型和位置，您可以采用不同的方法来调查并修复资源。

检查 Controller 节点问题
如果对 Controller 节点的健康检查失败，这可能代表 Controller 节点之间的通信问题。要调查，请登录 Controller 节点并检查服务是否可以正确启动。
调查单个资源问题
如果控制器上的大部分服务都正确运行，您可以运行 pcs status 命令并检查输出以了解有关特定服务故障的信息。您还可以登录到资源失败的 Controller，并调查 Controller 节点上的资源行为。

流程

以下流程演示了如何调查 openstack-cinder-volume 资源。

  1. 找到并登录到资源出现故障的 Controller 节点。

  2. 运行 systemctl status 命令以显示资源状态和最近的日志事件： 

    [heat-admin@overcloud-controller-0 ~]$ sudo systemctl status openstack-cinder-volume

  3. 根据输出中的信息更正失败的资源。

  4. 运行 pcs resource cleanup 命令以重置状态以及资源失败计数。 

    $ sudo pcs resource cleanup openstack-cinder-volume
  Resource: openstack-cinder-volume successfully cleaned up
