8.7. 验证替换的 DistributedComputeHCI 节点的功能

  1. 确保 status 字段的值 已启用，并且 State 字段的值为 up ： 

    (central) [stack@site-undercloud-0 ~]$ openstack compute service list -c Binary -c Host -c Zone -c Status -c State
+----------------+-----------------------------------------+------------+---------+-------+
| Binary         | Host                                    | Zone       | Status  | State |
+----------------+-----------------------------------------+------------+---------+-------+
...
| nova-compute   | dcn1-compute1-0.redhat.local            | az-dcn1    | enabled | up    |
| nova-compute   | dcn1-compute1-1.redhat.local            | az-dcn1    | enabled | up    |
| nova-compute   | dcn2-computehciscaleout2-0.redhat.local | az-dcn2    | enabled | up    |
| nova-compute   | dcn2-computehci2-0.redhat.local         | az-dcn2    | enabled | up    |
| nova-compute   | dcn2-computescaleout2-0.redhat.local    | az-dcn2    | enabled | up    |
| nova-compute   | dcn2-computehci2-2.redhat.local         | az-dcn2    | enabled | up    |
...

  2. 确保所有网络代理都处于 up 状态： 

    (central) [stack@site-undercloud-0 ~]$ openstack network agent list -c "Agent Type" -c Host -c Alive -c State
+--------------------+-----------------------------------------+-------+-------+
| Agent Type         | Host                                    | Alive | State |
+--------------------+-----------------------------------------+-------+-------+
| DHCP agent         | dcn3-compute3-1.redhat.local            | :-)   | UP    |
| Open vSwitch agent | central-computehci0-1.redhat.local      | :-)   | UP    |
| DHCP agent         | dcn3-compute3-0.redhat.local            | :-)   | UP    |
| DHCP agent         | central-controller0-2.redhat.local      | :-)   | UP    |

  3. 验证 Ceph 集群的状态：

    1. 使用 SSH 连接到新的 DistributedComputeHCI 节点，并检查 Ceph 集群的状态： 

      [root@dcn2-computehci2-5 ~]# podman exec -it ceph-mon-dcn2-computehci2-5 \
ceph -s -c /etc/ceph/dcn2.conf
      Copy to Clipboard Toggle word wrap

    2. 验证新节点的 ceph mon 和 ceph mgr 服务都存在： 

      services:
    mon: 3 daemons, quorum dcn2-computehci2-2,dcn2-computehci2-0,dcn2-computehci2-5 (age 3d)
    mgr: dcn2-computehci2-2(active, since 3d), standbys: dcn2-computehci2-0, dcn2-computehci2-5
    osd: 20 osds: 20 up (since 3d), 20 in (since 3d)
      Copy to Clipboard Toggle word wrap

    3. 使用 'ceph osd tree' 验证 ceph osds 的状态。确保我们的新节点的所有 osds 都位于 STATUS up 中： 

      [root@dcn2-computehci2-5 ~]# podman exec -it ceph-mon-dcn2-computehci2-5 ceph osd tree -c /etc/ceph/dcn2.conf
ID CLASS WEIGHT  TYPE NAME                           STATUS REWEIGHT PRI-AFF

  4. 验证新 DistributedComputeHCI 节点的 cinder-volume 服务是否处于 Status 'enabled' 和 in State 'up' 中： 

    (central) [stack@site-undercloud-0 ~]$ openstack volume service list --service cinder-volume -c Binary -c Host -c Zone -c Status -c State
+---------------+---------------------------------+------------+---------+-------+
| Binary        | Host                            | Zone       | Status  | State |
+---------------+---------------------------------+------------+---------+-------+
| cinder-volume | hostgroup@tripleo_ceph          | az-central | enabled | up    |
| cinder-volume | dcn1-compute1-1@tripleo_ceph    | az-dcn1    | enabled | up    |
| cinder-volume | dcn1-compute1-0@tripleo_ceph    | az-dcn1    | enabled | up    |
| cinder-volume | dcn2-computehci2-0@tripleo_ceph | az-dcn2    | enabled | up    |
| cinder-volume | dcn2-computehci2-2@tripleo_ceph | az-dcn2    | enabled | up    |
| cinder-volume | dcn2-computehci2-5@tripleo_ceph | az-dcn2    | enabled | up    |
+---------------+---------------------------------+------------+---------+-------+

    注意

    如果 cinder-volume 服务的 State 为 down，则该服务尚未在节点上启动。

  5. 使用 ssh 连接到新的 DistributedComputeHCI 节点，并使用 'systemctl' 检查 Glance 服务的状态： 

    [root@dcn2-computehci2-5 ~]# systemctl --type service | grep glance
  tripleo_glance_api.service                        loaded active     running       glance_api container
  tripleo_glance_api_healthcheck.service            loaded activating start   start glance_api healthcheck
  tripleo_glance_api_tls_proxy.service              loaded active     running       glance_api_tls_proxy container
