控制器伺服器UCS C240 M4的PCRF更換
目錄
簡介
本文檔介紹在託管CPS虛擬網路功能(VNF)的Ultra-M設定中更換故障控制器伺服器所需的步驟。
必要條件
備份
在進行恢復時，思科建議使用以下步驟備份OSPD資料庫(DB):
[root@director ~]# mysqldump --opt --all-databases > /root/undercloud-all-databases.sql
[root@director ~]# tar --xattrs -czf undercloud-backup-`date +%F`.tar.gz /root/undercloud-all-databases.sql
/etc/my.cnf.d/server.cnf /var/lib/glance/images /srv/node /home/stack
tar: Removing leading `/' from member names
初步狀態檢查
請務必檢查OpenStack環境和服務的當前狀態，並確保其處於正常狀態，然後再繼續更換過程。它有助於避免控制器更換過程中的複雜性。
步驟1.檢查OpenStack的狀態和節點清單：
[stack@director ~]$ source stackrc
[stack@director ~]$ openstack stack list --nested
[stack@director ~]$ ironic node-list
[stack@director ~]$ nova list
步驟2.檢查控制器上的心臟起搏器狀態。
登入其中一個作用中控制器並檢查心臟起搏器狀態。所有服務應在可用控制器上運行並在出現故障的控制器上停止。

在此範例中，Controller-2處於離線狀態。因此，它將被取代。Controller-0和Controller-1運行正常且運行群集服務。
步驟3.檢查作用中控制器的MariaDB狀態。
[stack@director] nova list | grep control
| 4361358a-922f-49b5-89d4-247a50722f6d | pod1-controller-0 | ACTIVE | - | Running | ctlplane=192.200.0.102 |
| d0f57f27-93a8-414f-b4d8-957de0d785fc | pod1-controller-1 | ACTIVE | - | Running | ctlplane=192.200.0.110 |
[stack@director ~]$ for i in 192.200.0.102 192.200.0.110 ; do echo "*** $i ***" ; ssh heat-admin@$i "sudo mysql --exec=\"SHOW STATUS LIKE 'wsrep_local_state_comment'\" ; sudo mysql --exec=\"SHOW STATUS LIKE 'wsrep_cluster_size'\""; done
*** 192.200.0.152 ***
Variable_name Value
wsrep_local_state_comment Synced
Variable_name Value
wsrep_cluster_size 2
*** 192.200.0.154 ***
Variable_name Value
wsrep_local_state_comment Synced
Variable_name Value
wsrep_cluster_size 2
驗證每個作用中控制器是否存在以下線路：
wsrep_local_state_comment:已同步
wsrep_cluster_size:2
步驟4.檢查作用中控制器的Rabbitmq狀態。發生故障的控制器不應出現在運行的節點清單中。
[heat-admin@pod1-controller-0 ~] sudo rabbitmqctl cluster_status
Cluster status of node 'rabbit@pod1-controller-0' ...
[{nodes,[{disc,['rabbit@pod1-controller-0','rabbit@pod1-controller-1',
'rabbit@pod1-controller-2']}]},
{running_nodes,['rabbit@pod1-controller-1',
'rabbit@pod1-controller-0']},
{cluster_name,<<"rabbit@pod1-controller-2.localdomain">>},
{partitions,[]},
{alarms,[{'rabbit@pod1-controller-1',[]},
{'rabbit@pod1-controller-0',[]}]}]
[heat-admin@pod1-controller-1 ~] sudo rabbitmqctl cluster_status
Cluster status of node 'rabbit@pod1-controller-1' ...
[{nodes,[{disc,['rabbit@pod1-controller-0','rabbit@pod1-controller-1',
'rabbit@pod1-controller-2']}]},
{running_nodes,['rabbit@pod1-controller-0',
'rabbit@pod1-controller-1']},
{cluster_name,<<"rabbit@pod1-controller-2.localdomain">>},
{partitions,[]},
{alarms,[{'rabbit@pod1-controller-0',[]},
{'rabbit@pod1-controller-1',[]}]}]
步驟5.檢查是否所有底層雲服務都處於OSP-D節點的已載入、活動和運行狀態。

安裝新控制器節點
步驟1.安裝新UCS C240 M4伺服器的步驟和初始設定步驟可從Cisco UCS C240 M4伺服器安裝和服務指南中參考
步驟2.使用CIMC IP登入伺服器。
步驟3.如果韌體與以前使用的推薦版本不一致，請執行BIOS升級。BIOS升級步驟如下：
步驟4.檢驗物理驅動器的狀態。必須是Unconfigured Good。導航到儲存> Cisco 12G SAS模組化Raid控制器(SLOT-HBA)>物理驅動器資訊。
步驟5.要從具有RAID級別1的物理驅動器建立虛擬驅動器：導覽至Storage > Cisco 12G SAS Modular Raid Controller(SLOT-HBA)> Controller Info > Create Virtual Drive from Unused Physical Drives，如下圖所示。
- 選擇VD並配置Set as Boot Drive:
步驟6.要啟用IPMI over LAN，請導航到Admin > Communication Services > Communication Services。
步驟7。若要停用超執行緒，請導覽至Compute > BIOS > Configure BIOS > Advanced > Processor Configuration，如下圖所示。
Overcloud中的控制器節點更換
本節說明使用重疊雲中的新控制器替換有故障的控制器所需的步驟。為此，將重新使用用於啟動堆疊的deploy.sh指令碼。在部署時，在ControllerNodesPostDeployment階段，由於Puppet模組中的某些限制，更新將失敗。重新啟動部署指令碼之前需要手動干預。
準備刪除失敗的控制器節點
步驟1.識別發生故障的控制器的索引。索引是OpenStack伺服器清單輸出中控制器名稱的數字字尾。在本例中，索引為2:
[stack@director ~]$ nova list | grep controller
| 5813a47e-af27-4fb9-8560-75decd3347b4 | pod1-controller-0 | ACTIVE | - | Running | ctlplane=192.200.0.152 |
| 457f023f-d077-45c9-bbea-dd32017d9708 | pod1-controller-1 | ACTIVE | - | Running | ctlplane=192.200.0.154 |
| d13bb207-473a-4e42-a1e7-05316935ed65 | pod1-controller-2 | ACTIVE | - | Running | ctlplane=192.200.0.151 |
步驟2.建立定義要刪除的節點的Yaml檔案~templates/remove-controller.yaml。將上一步中找到的索引用於資源清單中的條目。
[stack@director ~]$ cat templates/remove-controller.yaml
parameters:
ControllerRemovalPolicies:
[{'resource_list': [‘2’]}]
parameter_defaults:
CorosyncSettleTries: 5
步驟3.製作用於安裝重疊雲的部署指令碼的副本，並插入一行，以便包含之前建立的remove-controller.yaml檔案。
[stack@director ~]$ cp deploy.sh deploy-removeController.sh
[stack@director ~]$ cat deploy-removeController.sh
time openstack overcloud deploy --templates \
-r ~/custom-templates/custom-roles.yaml \
-e /home/stack/templates/remove-controller.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml \

-e ~/custom-templates/network.yaml \
-e ~/custom-templates/ceph.yaml \
-e ~/custom-templates/compute.yaml \
-e ~/custom-templates/layout-removeController.yaml \
-e ~/custom-templates/rabbitmq.yaml \
--stack pod1 \

--neutron-network-vlan-ranges datacentre:101:200 \
--neutron-disable-tunneling \
--verbose --timeout 180
步驟4.使用此處提及的命令，確定要替換的控制器的ID，並將其移至維護模式。
[stack@director ~]$ nova list | grep controller

步驟5. 為了確保資料庫在替換過程時運行，請從起搏器控制元件中刪除Galera，並在其中一個活動控制器上運行此命令。
[root@pod1-controller-0 ~]# sudo pcs resource unmanage galera
[root@pod1-controller-0 ~]# sudo pcs status

<snip>
準備新增新控制器節點
步驟1。建立一個controllerRMA.json檔案，並僅包含新的控制器詳細資訊。請確保以前未使用過新控制器上的索引號。通常，遞增到下一個最高控制器編號。
範例：之前的版本最高的是Controller-2，因此請建立Controller-3。
[stack@director ~]$ cat controllerRMA.json
{
"nodes": [
{
"mac": [
<MAC_ADDRESS>
],
"capabilities": "node:controller-3,boot_option:local",
"cpu": "24",
"memory": "256000",
"disk": "3000",
"arch": "x86_64",
"pm_type": "pxe_ipmitool",
"pm_user": "admin",
"pm_password": "<PASSWORD>",
"pm_addr": "<CIMC_IP>"
}
]
}
步驟2.使用在上一步中建立的json檔案匯入新節點。
[stack@director ~]$ openstack baremetal import --json controllerRMA.json
Started Mistral Workflow. Execution ID: 67989c8b-1225-48fe-ba52-3a45f366e7a0

[stack@director ~]$ openstack baremetal node list | grep available
| 048ccb59-89df-4f40-82f5-3d90d37ac7dd | None | None | power off | available | False
步驟3.將節點設定為管理狀態。
[stack@director ~]$ openstack baremetal node manage 048ccb59-89df-4f40-82f5-3d90d37ac7dd
[stack@director ~]$ openstack baremetal node list | grep off
| 048ccb59-89df-4f40-82f5-3d90d37ac7dd | None | None | power off | manageable | False |
步驟4.運行內檢。
[stack@director ~]$ openstack overcloud node introspect 048ccb59-89df-4f40-82f5-3d90d37ac7dd --provide
Started Mistral Workflow. Execution ID: f73fb275-c90e-45cc-952b-bfc25b9b5727

[stack@director ~]$ openstack baremetal node list | grep available
| 048ccb59-89df-4f40-82f5-3d90d37ac7dd | None | None | power off | available | False |
步驟5.使用新的控制器屬性標籤可用節點。確保使用為新控制器指定的控制器ID，如controllerRMA.json檔案中使用。
[stack@director ~]$ openstack baremetal node set --property capabilities='node:controller-3,profile:control,boot_option:local' 048ccb59-89df-4f40-82f5-3d90d37ac7dd
步驟6.在部署指令碼中，有一個名為layout.yaml的自定義模板，該模板除了其他功能之外，還指定將哪些IP地址分配給各個介面的控制器。在新堆疊上，為Controller-0、Controller-1和Controller-2定義了3個地址。新增新控制器時，請確保按順序為每個子網新增下一個IP地址。
ControllerIPs:
internal_api:
- 11.120.0.10

- 11.119.0.10
- 11.119.0.11
- 11.119.0.12
- 11.119.0.13
步驟7.現在運行之前建立的deploy-removecontroller.sh，以刪除舊節點並新增新節點。
[stack@b10-ospd ~]$ ./deploy-addController.sh
START with options: [u'overcloud', u'deploy', u'--templates', u'-r', u'/home/stack/custom-templates/custom-roles.yaml', u'-e', u'/usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml', u'-e', u'/usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml', u'-e', u'/usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml', u'-e', u'/usr/share/openstack-tripleo-heat-templates/environments/neutron-sriov.yaml', u'-e', u'/home/stack/custom-templates/network.yaml', u'-e', u'/home/stack/custom-templates/ceph.yaml', u'-e', u'/home/stack/custom-templates/compute.yaml', u'-e', u'/home/stack/custom-templates/layout-removeController.yaml', u'-e', u'/home/stack/custom-templates/rabbitmq.yaml', u'--stack', u'newtonoc', u'--debug', u'--log-file', u'overcloudDeploy_11_15_17__07_46_35.log', u'--neutron-flat-networks', u'phys_pcie1_0,phys_pcie1_1,phys_pcie4_0,phys_pcie4_1', u'--neutron-network-vlan-ranges', u'datacentre:101:200', u'--neutron-disable-tunneling', u'--verbose', u'--timeout', u'180']

手動干預
步驟1.在OSP-D伺服器上，執行OpenStack server list指令以列出可用控制器。新增的控制器應該會出現在清單中。
[stack@director ~]$ openstack server list | grep controller
| 3e6c3db8-ba24-48d9-b0e8-1e8a2eb8b5ff | pod1-controller-3 | ACTIVE | ctlplane=192.200.0.103 | overcloud-full |
| 457f023f-d077-45c9-bbea-dd32017d9708 | pod1-controller-1 | ACTIVE | ctlplane=192.200.0.154 | overcloud-full |
| 5813a47e-af27-4fb9-8560-75decd3347b4 | pod1-controller-0 | ACTIVE | ctlplane=192.200.0.152 | overcloud-full |
步驟2.連線至其中一個作用中控制器（不是新增的控制器），並檢視檔案/etc/corosync/corosycn.conf。找到nodelist，該清單為每個控制器分配nodeid。找到失敗節點的條目，並記下其nodeid:
[root@pod1-controller-0 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod1-controller-0
nodeid: 5
}
node {
ring0_addr: pod1-controller-1
nodeid: 7
}
node {
ring0_addr: pod1-controller-2
nodeid: 8
}
}
步驟3.登入每個作用中控制器。刪除出現故障的節點並重新啟動服務。在這種情況下，請移除pod1-controller-2。不要在新新增的控制器上執行此操作。
[root@pod1-controller-0 ~]# sudo pcs cluster localnode remove pod1-controller-2
pod1-controller-2: successfully removed!
[root@pod1-controller-0 ~]# sudo pcs cluster reload corosync
Corosync reloaded
[root@pod1-controller-1 ~]# sudo pcs cluster localnode remove pod1-controller-2
pod1-controller-2: successfully removed!
[root@pod1-controller-1 ~]# sudo pcs cluster reload corosync
Corosync reloaded
步驟4. 從其中一個活動控制器運行此命令，以便從群集中刪除故障節點。
[root@pod1-controller-0 ~]# sudo crm_node -R pod1-controller-2 --force
步驟5.從其中一個活動控制器運行此命令，以便從rabbitmq群集中刪除故障節點。
[root@pod1-controller-0 ~]# sudo rabbitmqctl forget_cluster_node rabbit@pod1-controller-2
Removing node 'rabbit@newtonoc-controller-2' from cluster ...
步驟6.從MongoDB中刪除故障節點。為此，您需要找到活動的Mongo節點。使用netstat查詢主機的IP地址。
[root@pod1-controller-0 ~]# sudo netstat -tulnp | grep 27017
tcp 0 0 11.120.0.10:27017 0.0.0.0:* LISTEN 219577/mongod
步驟7.使用先前命令的IP位址和連線埠號碼登入節點並檢查其是否為主機。
[heat-admin@pod1-controller-0 ~]$ echo "db.isMaster()" | mongo --host 11.120.0.10:27017
MongoDB shell version: 2.6.11
connecting to: 11.120.0.10:27017/test

"maxWireVersion" : 2,
"minWireVersion" : 0,
"ok" : 1
}
如果節點不是主節點，請登入到另一個活動控制器並執行相同步驟。
步驟8.在主機上使用rs.status()命令列出可用節點。查詢舊/無響應節點並標識mongo節點名稱。
[root@pod1-controller-0 ~]# mongo --host 11.120.0.10
MongoDB shell version: 2.6.11
connecting to: 11.120.0.10:27017/test

"pingMs" : 0,
"syncingTo" : "11.120.0.10:27017"
}
],
"ok" : 1
}
步驟9.使用rs.remove指令，從主機刪除失敗的節點。運行此命令時出現一些錯誤，但再次檢查狀態以發現節點已刪除：
[root@pod1-controller-0 ~]$ mongo --host 11.120.0.10
<snip>

bye
步驟10.運行此命令可更新活動控制器節點清單。在此清單中包括新控制器節點。
[root@pod1-controller-0 ~]# sudo pcs resource update galera wsrep_cluster_address=gcomm://pod1-controller-0,pod1-controller-1,pod1-controller-2
步驟11.將這些檔案從已存在之控制器複製到新控制器：
/etc/sysconfig/clustercheck
/root/.my.cnf
On existing controller:
[root@pod1-controller-0 ~]# scp /etc/sysconfig/clustercheck stack@192.200.0.1:/tmp/.
[root@pod1-controller-0 ~]# scp /root/.my.cnf stack@192.200.0.1:/tmp/my.cnf
On new controller:
[root@pod1-controller-3 ~]# cd /etc/sysconfig
[root@pod1-controller-3 sysconfig]# scp stack@192.200.0.1:/tmp/clustercheck .
[root@pod1-controller-3 sysconfig]# cd /root
[root@pod1-controller-3 ~]# scp stack@192.200.0.1:/tmp/my.cnf .my.cnf
步驟12.從已存在的控制器之一運行cluster node add命令。
[root@pod1-controller-1 ~]# sudo pcs cluster node add pod1-controller-3
Disabling SBD service...
pod1-controller-3: sbd disabled
pod1-controller-0: Corosync updated
pod1-controller-1: Corosync updated
Setting up corosync...
pod1-controller-3: Succeeded
Synchronizing pcsd certificates on nodes pod1-controller-3...
pod1-controller-3: Success
Restarting pcsd on the nodes in order to reload the certificates...
pod1-controller-3: Success
步驟13.登入每個控制器並檢視/etc/corosync/corosync.conf檔案。確保列出新控制器，且未指派給該控制器的節點是序列中先前未使用的下一個編號。確保在所有3個控制器上完成此更改。
[root@pod1-controller-1 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod1-controller-0
nodeid: 5
}
node {
ring0_addr: pod1-controller-1
nodeid: 7
}
node {
ring0_addr: pod1-controller-3
nodeid: 6
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
}
例如，修改後/etc/corosync/corosync.conf:
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod1-controller-0
nodeid: 5
}
node {
ring0_addr: pod1-controller-1
nodeid: 7
}
node {
ring0_addr: pod1-controller-3
nodeid: 9
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
}
步驟14.在作用中控制器上重新啟動corosync。不要在新控制器上啟動corosync。
[root@pod1-controller-0 ~]# sudo pcs cluster reload corosync
[root@pod1-controller-1 ~]# sudo pcs cluster reload corosync
步驟15.從其中一個作用控制器啟動新控制器節點。
[root@pod1-controller-1 ~]# sudo pcs cluster start pod1-controller-3
步驟16.從其中一個作用控制器重新啟動Galera。
[root@pod1-controller-1 ~]# sudo pcs cluster start pod1-controller-3
pod1-controller-0: Starting Cluster...
[root@pod1-controller-1 ~]# sudo pcs resource cleanup galera
Cleaning up galera:0 on pod1-controller-0, removing fail-count-galera
Cleaning up galera:0 on pod1-controller-1, removing fail-count-galera
Cleaning up galera:0 on pod1-controller-3, removing fail-count-galera
* The configuration prevents the cluster from stopping or starting 'galera-master' (unmanaged)
Waiting for 3 replies from the CRMd... OK
[root@pod1-controller-1 ~]#
[root@pod1-controller-1 ~]# sudo pcs resource manage galera
步驟17.群集處於維護模式。禁用維護模式以使服務啟動。
[root@pod1-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
步驟18.檢查Galera的PC狀態，直到所有3個控制器都列為Galera的主控制器。
[root@pod1-controller-1 ~]# sudo pcs status | grep galera -A1
Master/Slave Set: galera-master [galera]
Masters: [ pod1-controller-0 pod1-controller-1 pod1-controller-3 ]
步驟19.將群集切換到維護模式。
[root@pod1-controller-1~]# sudo pcs property set maintenance-mode=true --wait
[root@pod1-controller-1 ~]# pcs cluster status
Cluster Status:
Stack: corosync
Current DC: pod1-controller-0 (version 1.1.15-11.el7_3.4-e174ec8) - partition with quorum

步驟20.重新運行之前運行的部署指令碼。這一次應該會成功。
[stack@director ~]$ ./deploy-addController.sh

驗證控制器中的超雲服務
確保所有託管服務在控制器節點上正常運行。
[heat-admin@pod1-controller-2 ~]$ sudo pcs status
完成L3代理路由器
檢查路由器以確保第3層代理正確託管。執行此檢查時，請確保源位置為overcloudc檔案。
步驟1.查詢路由器名稱。
[stack@director~]$ source corerc
[stack@director ~]$ neutron router-list
+--------------------------------------+------+-------------------------------------------------------------------+-------------+------+
| id | name | external_gateway_info | distributed | ha |
+--------------------------------------+------+-------------------------------------------------------------------+-------------+------+
| d814dc9d-2b2f-496f-8c25-24911e464d02 | main | {"network_id": "18c4250c-e402-428c-87d6-a955157d50b5", | False | True |
在本範例中，路由器的名稱是main。
步驟2.列出所有L3代理，以便找到故障節點和新節點的UUID。
[stack@director ~]$ neutron agent-list | grep "neutron-l3-agent"
| 70242f5c-43ab-4355-abd6-9277f92e4ce6 | L3 agent | pod1-controller-0.localdomain | nova | :-) | True | neutron-l3-agent |
| 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40 | L3 agent | pod1-controller-2.localdomain | nova | xxx | True | neutron-l3-agent |
| a410a491-e271-4938-8a43-458084ffe15d | L3 agent | pod1-controller-3.localdomain | nova | :-) | True | neutron-l3-agent |
| cb4bc1ad-ac50-42e9-ae69-8a256d375136 | L3 agent | pod1-controller-1.localdomain | nova | :-) | True | neutron-l3-agent |
步驟3.在本例中，應從路由器中移除對應於pod1-controller-2.localdomain的第3層代理，並將對應於pod1-controller-3.localdomain的L3代理新增到路由器中。
[stack@director ~]$ neutron l3-agent-router-remove 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40 main
Removed router main from L3 agent
[stack@director ~]$ neutron l3-agent-router-add a410a491-e271-4938-8a43-458084ffe15d main
Added router main to L3 agent
步驟4.檢查L3-Agent的更新清單。
[stack@director ~]$ neutron l3-agent-list-hosting-router main
+--------------------------------------+-----------------------------------+----------------+-------+----------+
| id | host | admin_state_up | alive | ha_state |
+--------------------------------------+-----------------------------------+----------------+-------+----------+

| a410a491-e271-4938-8a43-458084ffe15d | pod1-controller-3.localdomain | True | :-) | standby |
| cb4bc1ad-ac50-42e9-ae69-8a256d375136 | pod1-controller-1.localdomain | True | :-) | active |
+--------------------------------------+-----------------------------------+----------------+-------+----------+
步驟5.列出從已移除的控制器節點運行的所有服務，並將其移除。
[stack@director ~]$ neutron agent-list | grep controller-2
| 877314c2-3c8d-4666-a6ec-69513e83042d | Metadata agent | pod1-controller-2.localdomain | | xxx | True | neutron-metadata-agent |
| 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40 | L3 agent | pod1-controller-2.localdomain | nova | xxx | True | neutron-l3-agent |

[stack@director ~]$ neutron agent-delete 911c43a5-df3a-49ec-99ed-1d722821ec20
Deleted agent(s): 911c43a5-df3a-49ec-99ed-1d722821ec20
[stack@director ~]$ neutron agent-delete a58a3dd3-4cdc-48d4-ab34-612a6cd72768
Deleted agent(s): a58a3dd3-4cdc-48d4-ab34-612a6cd72768
[stack@director ~]$ neutron agent-list | grep controller-2
[stack@director ~]$
最終確定計算服務
步驟1。檢查從移除的節點中留下的新星服務清單項並將其刪除。
[stack@director ~]$ nova service-list | grep controller-2
| 615 | nova-consoleauth | pod1-controller-2.localdomain | internal | enabled | down | 2017-11-16T16:08:14.000000 | - |
| 618 | nova-scheduler | pod1-controller-2.localdomain | internal | enabled | down | 2017-11-16T16:08:13.000000 | - |
| 621 | nova-conductor | pod1-controller-2.localdomain | internal | enabled | down | 2017-11-16T16:08:14.000000 | -
[stack@director ~]$ nova service-delete 615
[stack@director ~]$ nova service-delete 618
[stack@director ~]$ nova service-delete 621
stack@director ~]$ nova service-list | grep controller-2
步驟2. 確保consoleauth程式在所有控制器上執行，或使用以下命令重新啟動該程式：pc資源重新啟動openstack-nova-consoleauth:
[stack@director ~]$ nova service-list | grep consoleauth
| 601 | nova-consoleauth | pod1-controller-0.localdomain | internal | enabled | up | 2017-11-16T21:00:10.000000 | - |
| 608 | nova-consoleauth | pod1-controller-1.localdomain | internal | enabled | up | 2017-11-16T21:00:13.000000 | - |
| 622 | nova-consoleauth | pod1-controller-3.localdomain | internal | enabled | up | 2017-11-16T21:00:13.000000 | -
在控制器節點上重新啟動圍欄
步驟1. 檢查所有控制器中是否有通往底層雲192.0.0.0/8的IP路由
[root@pod1-controller-3 ~]# ip route
default via 172.25.22.1 dev vlan101
11.117.0.0/24 dev vlan17 proto kernel scope link src 11.117.0.12
11.118.0.0/24 dev vlan18 proto kernel scope link src 11.118.0.12
11.119.0.0/24 dev vlan19 proto kernel scope link src 11.119.0.12
11.120.0.0/24 dev vlan20 proto kernel scope link src 11.120.0.12
169.254.169.254 via 192.200.0.1 dev eno1
172.25.22.0/24 dev vlan101 proto kernel scope link src 172.25.22.102
192.0.0.0/8 dev eno1 proto kernel scope link src 192.200.0.103
步驟2.檢查當前的石塊配置。刪除對舊控制器節點的任何引用。
