更換控制器伺服器UCS C240 M4 - CPAR
目錄
簡介
本文檔介紹在Ultra-M設定中更換有故障的控制器伺服器所需的步驟。
此過程適用於使用NEWTON版本的Openstack環境，其中Elastic Services Controller(ESC)不管理Cisco Prime Access Registrar(CPAR)，並且CPAR直接安裝在Openstack上部署的VM上。
背景資訊
Ultra-M是經過預先打包和驗證的虛擬化移動資料包核心解決方案，旨在簡化VNF的部署。OpenStack是適用於Ultra-M的虛擬化基礎架構管理員(VIM)，由以下節點型別組成：
- 計算
- 對象儲存磁碟 — 計算（OSD — 計算）
- 控制器
- OpenStack平台 — 導向器(OSPD)
Ultra-M的高級架構和涉及的元件如下圖所示：
本文檔面向熟悉Cisco Ultra-M平台的思科人員，詳細說明了在OpenStack和Redhat作業系統上需要執行的步驟。

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。
[stack@pod2-stack-controller-0 ~]# pcs status <snip> Online: [ pod2-stack-controller-0 pod2-stack-controller-1 ] Offline: [ pod2-stack-controller-2 ] Full list of resources: ip-11.120.0.109 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 ip-172.25.22.109 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-1 ip-192.200.0.107 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 Clone Set: haproxy-clone [haproxy] Started: [ pod2-stack-controller-0 pod2-stack-controller-1 ] Stopped: [ pod2-stack-controller-2 ] Master/Slave Set: galera-master [galera] Masters: [ pod2-stack-controller-0 pod2-stack-controller-1 ] Stopped: [ pod2-stack-controller-2 ] ip-11.120.0.110 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 ip-11.119.0.110 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-1 Clone Set: rabbitmq-clone [rabbitmq] Started: [ pod2-stack-controller-0 pod2-stack-controller-1 ] Stopped: [ pod2-stack-controller-2 ] Master/Slave Set: redis-master [redis] Masters: [ pod2-stack-controller-0 ] Slaves: [ pod2-stack-controller-1 ] Stopped: [ pod2-stack-controller-2 ] ip-11.118.0.104 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-1 openstack-cinder-volume (systemd:openstack-cinder-volume): Started pod2-stack-controller-0 my-ipmilan-for-controller-6 (stonith:fence_ipmilan): Started pod2-stack-controller-1 my-ipmilan-for-controller-4 (stonith:fence_ipmilan): Started pod2-stack-controller-0 my-ipmilan-for-controller-7 (stonith:fence_ipmilan): Started pod2-stack-controller-0 Failed Actions: Daemon Status: corosync: active/enabled pacemaker: active/enabled pcsd: active/enabled
在此範例中，Controller-2處於離線狀態。因此，它被替換了。Controller-0和Controller-1運行正常運行並運行群集服務。
步驟3.檢查作用中控制器中的MariaDB狀態：
[stack@director] nova list | grep control
| b896c73f-d2c8-439c-bc02-7b0a2526dd70 | pod2-stack-controller-0 | ACTIVE | - | Running | ctlplane=192.200.0.113 |
| 2519ce67-d836-4e5f-a672-1a915df75c7c | pod2-stack-controller-1 | ACTIVE | - | Running | ctlplane=192.200.0.105 |
[stack@director ~]$ for i in 192.200.0.113 192.200.0.105 ; 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
*** 192.200.0.113 ***
Variable_nameValue
wsrep_local_state_comment Synced
Variable_nameValue
wsrep_cluster_size 2
*** 192.200.0.105 ***
Variable_nameValue
wsrep_local_state_comment Synced
Variable_nameValue
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.檢查作用中控制器中的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@pod2-stack-controller-0 ~] sudo rabbitmqctl cluster_status
Cluster status of node 'rabbit@pod2-stack-controller-0' ...
[{nodes,[{disc,['rabbit@pod2-stack-controller-0','rabbit@pod2-stack-controller-1',
'rabbit@pod2stack-controller-2']}]},
{running_nodes,['rabbit@pod2-stack-controller-1',
'rabbit@pod2-stack-controller-0']},
{cluster_name,<<"rabbit@pod2-stack-controller-2.localdomain">>},
{partitions,[]},
{alarms,[{'rabbit@pod2-stack-controller-1',[]},
{'rabbit@pod2-stack-controller-0',[]}]}]
[heat-admin@pod2-stack-controller-1 ~] sudo rabbitmqctl cluster_status
Cluster status of node 'rabbit@pod2-stack-controller-1' ...
[{nodes,[{disc,['rabbit@pod2-stack-controller-0','rabbit@pod2-stack-controller-1',
'rabbit@pod2-stack-controller-2']}]},
{running_nodes,['rabbit@pod2-stack-controller-0',
'rabbit@pod2-stack-controller-1']},
{cluster_name,<<"rabbit@pod2-stack-controller-2.localdomain">>},
{partitions,[]},
{alarms,[{'rabbit@pod2-stack-controller-0',[]},
{'rabbit@pod2-stack-controller-1',[]}]}]
步驟5.從OSP-D節點檢查是否所有底層雲服務均處於已載入、活動和運行狀態。
[stack@director ~]$ systemctl list-units "openstack*" "neutron*" "openvswitch*"

安裝新控制器節點
有關安裝新UCS C240 M4伺服器的步驟和初始設定步驟，請參閱：Cisco UCS C240 M4伺服器安裝和服務指南
步驟1.使用CIMC IP登入伺服器。
步驟2.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：Cisco UCS C系列機架式伺服器BIOS升級指南
步驟3。若要確認未設定良好的物理驅動器的狀態，請導覽至Storage > Cisco 12G SAS Modular Raid Controller(SLOT-HBA)> Physical Drive Info，如下圖所示。
步驟4.若要從RAID級別為1的物理驅動器建立虛擬驅動器，請導航到Storage > Cisco 12G SAS Modular Raid Controller(SLOT-HBA)> Controller Info > Create Virtual Drive from Unused Physical Drives。
- 選擇VD並配置設定為引導驅動器：
步驟5.要啟用IPMI over LAN，請導航到Admin > Communication Services > Communication Services。
步驟6。若要停用超執行緒，請導覽至Compute > BIOS > Configure BIOS > Advanced > Processor Configuration。
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.shscript。在部署時，在控制器節點後期部署階段，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.確定故障控制器的索引。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
| b896c73f-d2c8-439c-bc02-7b0a2526dd70 | pod2-stack-controller-0 | ACTIVE | - | Running | ctlplane=192.200.0.113 |
| 2519ce67-d836-4e5f-a672-1a915df75c7c | pod2-stack-controller-1 | ACTIVE | - | Running | ctlplane=192.200.0.105 |
| e19b9625-5635-4a52-a369-44310f3e6a21 | pod2-stack-controller-2 | ACTIVE | - | Running | ctlplane=192.200.0.120 |
步驟2.建立Yaml檔案~templates/remove-controller.yamller，定義要刪除的節點。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.yamlfile:
[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 /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-sriov.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 pod2-stack \
--debug \
--log-file overcloudDeploy_$(date +%m_%d_%y__%H_%M_%S).log \
--neutron-flat-networks phys_pcie1_0,phys_pcie1_1,phys_pcie4_0,phys_pcie4_1 \
--neutron-network-vlan-ranges datacentre:101:200 \
--neutron-disable-tunneling \
--verbose --timeout 180
步驟4.使用此處提及的命令識別要更換的控制器的ID，並將其移至維護模式：
[stack@director ~]$ nova list | grep controller
| b896c73f-d2c8-439c-bc02-7b0a2526dd70 | pod2-stack-controller-0 | ACTIVE | - | Running | ctlplane=192.200.0.113 |
| 2519ce67-d836-4e5f-a672-1a915df75c7c | pod2-stack-controller-1 | ACTIVE | - | Running | ctlplane=192.200.0.105 |
| e19b9625-5635-4a52-a369-44310f3e6a21 | pod2-stack-controller-2 | ACTIVE | - | Running | ctlplane=192.200.0.120 |
[stack@director ~]$ openstack baremetal node list | grep e19b9625-5635-4a52-a369-44310f3e6a21
| e7c32170-c7d1-4023-b356-e98564a9b85b | None | e19b9625-5635-4a52-a369-44310f3e6a21 | power off | active | False |
[stack@b10-ospd ~]$ openstack baremetal node maintenance set e7c32170-c7d1-4023-b356-e98564a9b85b
[stack@director~]$ openstack baremetal node list | grep True
| e7c32170-c7d1-4023-b356-e98564a9b85b | None | e19b9625-5635-a369-44310f3e6a21 | power off | active | True |
步驟5.為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@pod2-stack-controller-0 ~]# sudo pcs resource unmanage galera
[root@pod2-stack-controller-0 ~]# sudo pcs status Cluster name: tripleo_cluster Stack: corosync Current DC: pod2-stack-controller-0 (version 1.1.15-11.el7_3.4-e174ec8) - partition with quorum Last updated: Thu Nov 16 16:51:18 2017 Last change: Thu Nov 16 16:51:12 2017 by root via crm_resource on pod2-stack-controller-0 3 nodes and 22 resources configured Online: [ pod2-stack-controller-0 pod2-stack-controller-1 ] OFFLINE: [ pod2-stack-controller-2 ] Full list of resources: ip-11.120.0.109 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 ip-172.25.22.109 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-1 ip-192.200.0.107 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 Clone Set: haproxy-clone [haproxy] Started: [ pod2-stack-controller-0 pod2-stack-controller-1 ] Stopped: [ pod2-stack-controller-2 ] Master/Slave Set: galera-master [galera] (unmanaged) galera (ocf::heartbeat:galera): Master pod2-stack-controller-0 (unmanaged) galera (ocf::heartbeat:galera): Master pod2-stack-controller-1 (unmanaged) Stopped: [ pod2-stack-controller-2 ] ip-11.120.0.110 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-0 ip-11.119.0.110 (ocf::heartbeat:IPaddr2): Started pod2-stack-controller-1 <snip>
準備新增新控制器節點
步驟1.建立僅包含新控制器詳細資訊的控制器RMA.jsonfile。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
Successfully registered node UUID 048ccb59-89df-4f40-82f5-3d90d37ac7dd
Started Mistral Workflow. Execution ID: c6711b5f-fa97-4c86-8de5-b6bc7013b398
Successfully set all nodes to available.
[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
Waiting for introspection to finish...
Successfully introspected all nodes.
Introspection completed.
Started Mistral Workflow. Execution ID: a892b456-eb15-4c06-b37e-5bc3f6c37c65
Successfully set all nodes to available
[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。確保使用指定給新控制器的控制器ID，如控制器RMA.jsonfile中所用：
[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，該模板除其他外，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
- 11.120.0.11
- 11.120.0.12
- 11.120.0.13
tenant:
- 11.117.0.10
- 11.117.0.11
- 11.117.0.12
- 11.117.0.13
storage:
- 11.118.0.10
- 11.118.0.11
- 11.118.0.12
- 11.118.0.13
storage_mgmt:
- 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.shh，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。新增的控制器應會顯示在此清單中：
[stack@director ~]$ openstack server list | grep controller-3
| 3e6c3db8-ba24-48d9-b0e8-1e8a2eb8b5ff | pod2-stack-controller-3 | ACTIVE | ctlplane=192.200.0.103 | 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/etc/corosync/corosycn.conf檔案。查詢enodelistt，它將附加項分配給每個控制器。找到失敗節點的條目，並注意itsnodeid:
[root@pod2-stack-controller-0 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod2-stack-controller-0
nodeid: 5
}
node {
ring0_addr: pod2-stack-controller-1
nodeid: 7
}
node {
ring0_addr: pod2-stack-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，為removepod2-stack-controller-2。請不要在新新增的控制器上執行此操作：
[root@pod2-stack-controller-0 ~]# sudo pcs cluster localnode remove pod2-stack-controller-2
pod2-stack-controller-2: successfully removed!
[root@pod2-stack-controller-0 ~]# sudo pcs cluster reload corosync
Corosync reloaded
[root@pod2-stack-controller-1 ~]# sudo pcs cluster localnode remove pod2-stack-controller-2
pod2-stack-controller-2: successfully removed!
[root@pod2-stack-controller-1 ~]# sudo pcs cluster reload corosync
Corosync reloaded
步驟4.從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@pod2-stack-controller-0 ~]# sudo crm_node -R pod2-stack-controller-2 --force
步驟5.從其中一個活動控制器運行此命令，以便從therabbitmqcluster中刪除失敗的節點：
[root@pod2-stack-controller-0 ~]# sudo rabbitmqctl forget_cluster_node rabbit@pod2-stack-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。Usenetstatto find the IP address of the host:
[root@pod2-stack-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.登入到節點並檢查它是否為主節點，方法是使用前面命令中的IP地址和埠號：
[heat-admin@pod2-stack-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
{

"secondary" : false,
"hosts" : [
"11.120.0.10:27017",
"11.120.0.12:27017",
"11.120.0.11:27017"
],
"primary" : "11.120.0.10:27017",
"me" : "11.120.0.10:27017",
"electionId" : ObjectId("5a0d2661218cb0238b582fb1"),
"maxBsonObjectSize" : 16777216,
"maxMessageSizeBytes" : 48000000,
"maxWriteBatchSize" : 1000,
"localTime" : ISODate("2017-11-16T18:36:34.473Z"),
"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1。在主節點上，使用thers.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@pod2-stack-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2.在主節點上，使用thers.removecommand刪除失敗節點。當您執行此命令時，會看到一些錯誤，但再次檢查狀態以發現節點已刪除：
[root@pod2-stack-controller-0 ~]$ mongo --host 11.120.0.10

步驟3.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@pod2-stack-controller-0 ~]# sudo pcs resource update galera wsrep_cluster_address=gcomm://pod2-stack-controller-0,pod2-stack-controller-1,pod2-stack-controller-2
步驟4.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@pod2-stack-controller-0 ~]# scp /etc/sysconfig/clustercheck stack@192.200.0.1:/tmp/.
[root@pod2-stack-controller-0 ~]# scp /root/.my.cnf stack@192.200.0.1:/tmp/my.cnf
On new controller:
[root@pod2-stack-controller-3 ~]# cd /etc/sysconfig
[root@pod2-stack-controller-3 sysconfig]# scp stack@192.200.0.1:/tmp/clustercheck .
[root@pod2-stack-controller-3 sysconfig]# cd /root
[root@pod2-stack-controller-3 ~]# scp stack@192.200.0.1:/tmp/my.cnf .my.cnf
步驟5.從已經存在的控制器之一運行luster node命令：
[root@pod2-stack-controller-1 ~]# sudo pcs cluster node add pod2-stack-controller-3
Disabling SBD service...
pod2-stack-controller-3: sbd disabled
pod2-stack-controller-0: Corosync updated
pod2-stack-controller-1: Corosync updated
Setting up corosync...
pod2-stack-controller-3: Succeeded
Synchronizing pcsd certificates on nodes pod2-stack-controller-3...
pod2-stack-controller-3: Success
Restarting pcsd on the nodes in order to reload the certificates...
pod2-stack-controller-3: Success
步驟6.登入每個控制器並檢視/etc/corosync/corosync.conf檔案。確保已列出新控制器，且序列中尚未使用的下一個編號是已分配給該控制器的節點。確保在所有3個控制器上完成此變更：
[root@pod2-stack-controller-1 ~]# cat /etc/corosync/corosync.conf
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod2-stack-controller-0
nodeid: 5
}
node {
ring0_addr: pod2-stack-controller-1
nodeid: 7
}
node {
ring0_addr: pod2-stack-controller-3
nodeid: 6
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
}
例如/etc/corosync/corosync.confafter修改：
totem {
version: 2
secauth: off
cluster_name: tripleo_cluster
transport: udpu
token: 10000
}
nodelist {
node {
ring0_addr: pod2-stack-controller-0
nodeid: 5
}
node {
ring0_addr: pod2-stack-controller-1
nodeid: 7
}
node {
ring0_addr: pod2-stack-controller-3
nodeid: 9
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
}
步驟7. 重新啟動活動控制器。請勿開啟新控制器：
[root@pod2-stack-controller-0 ~]# sudo pcs cluster reload corosync
[root@pod2-stack-controller-1 ~]# sudo pcs cluster reload corosync
步驟8.從其中一個作用控制器啟動新控制器節點：
[root@pod2-stack-controller-1 ~]# sudo pcs cluster start pod2-stack-controller-3
步驟9.從其中一個作用控制器重新啟動Galera:
[root@pod2-stack-controller-1 ~]# sudo pcs cluster start pod2-stack-controller-3
pod2-stack-controller-0: Starting Cluster...
[root@pod2-stack-controller-1 ~]# sudo pcs resource cleanup galera
Cleaning up galera:0 on pod2-stack-controller-0, removing fail-count-galera
Cleaning up galera:0 on pod2-stack-controller-1, removing fail-count-galera
Cleaning up galera:0 on pod2-stack-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@pod2-stack-controller-1 ~]#
[root@pod2-stack-controller-1 ~]# sudo pcs resource manage galera
步驟10.群集處於維護模式。禁用維護模式以啟動服務：
[root@pod2-stack-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
步驟11.檢查Galera的PC狀態，直到所有3個控制器都列為Galera中的主控制器：
[root@pod2-stack-controller-1 ~]# sudo pcs status | grep galera -A1
Master/Slave Set: galera-master [galera]
Masters: [ pod2-stack-controller-0 pod2-stack-controller-1 pod2-stack-controller-3 ]
步驟12.將群集切換到維護模式：
[root@pod2-stack-controller-1~]# sudo pcs property set maintenance-mode=true --wait
[root@pod2-stack-controller-1 ~]# pcs cluster status
Cluster Status:
Stack: corosync
Current DC: pod2-stack-controller-0 (version 1.1.15-11.el7_3.4-e174ec8) - partition with quorum
Last updated: Thu Nov 16 19:17:01 2017 Last change: Thu Nov 16 19:16:48 2017 by root via cibadmin on pod2-stack-controller-1
*** Resource management is DISABLED ***
The cluster will not attempt to start, stop or recover services
PCSD Status:
pod2-stack-controller-3: Online
pod2-stack-controller-0: Online
pod2-stack-controller-1: Online
步驟13.重新運行以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@pod2-stack-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.列出所有第3層代理，以便查詢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 | pod2-stack-controller-0.localdomain | nova | :-) | True | neutron-l3-agent |
| 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40 | L3 agent | pod2-stack-controller-2.localdomain | nova | xxx | True | neutron-l3-agent |
| a410a491-e271-4938-8a43-458084ffe15d | L3 agent | pod2-stack-controller-3.localdomain | nova | :-) | True | neutron-l3-agent |
| cb4bc1ad-ac50-42e9-ae69-8a256d375136 | L3 agent | pod2-stack-controller-1.localdomain | nova | :-) | True | neutron-l3-agent |
在本範例中，應從路由器中移除對應於pod2-stack-controller-2.localdomainer的第3層代理，並將對應於pod2-stack-controller-3.localdomainer的第3層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3.檢查更新的第3層代理清單：
[stack@director ~]$ neutron l3-agent-list-hosting-router main
+--------------------------------------+-----------------------------------+----------------+-------+----------+
| id | host | admin_state_up | alive | ha_state |
+--------------------------------------+-----------------------------------+----------------+-------+----------+
| 70242f5c-43ab-4355-abd6-9277f92e4ce6 | pod2-stack-controller-0.localdomain | True | :-) | standby |
| a410a491-e271-4938-8a43-458084ffe15d | pod2-stack-controller-3.localdomain | True | :-) | standby |
| cb4bc1ad-ac50-42e9-ae69-8a256d375136 | pod2-stack-controller-1.localdomain | True | :-) | active |
+--------------------------------------+-----------------------------------+----------------+-------+----------+
步驟4.列出從已刪除的控制器節點運行的所有服務並刪除它們：
[stack@director ~]$ neutron agent-list | grep controller-2
| 877314c2-3c8d-4666-a6ec-69513e83042d | Metadata agent | pod2-stack-controller-2.localdomain | | xxx | True | neutron-metadata-agent |
| 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40 | L3 agent | pod2-stack-controller-2.localdomain | nova | xxx | True | neutron-l3-agent |
| 911c43a5-df3a-49ec-99ed-1d722821ec20 | DHCP agent | pod2-stack-controller-2.localdomain | nova | xxx | True | neutron-dhcp-agent |
| a58a3dd3-4cdc-48d4-ab34-612a6cd72768 | Open vSwitch agent | pod2-stack-controller-2.localdomain | | xxx | True | neutron-openvswitch-agent |
[stack@director ~]$ neutron agent-delete 877314c2-3c8d-4666-a6ec-69513e83042d
Deleted agent(s): 877314c2-3c8d-4666-a6ec-69513e83042d
[stack@director ~]$ neutron agent-delete 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40
Deleted agent(s): 8d2ffbcb-b6ff-42cd-b5b8-da31d8da8a40
[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. Checknova service-list left from the removed node and delete them:
[stack@director ~]$ nova service-list | grep controller-2
| 615 | nova-consoleauth | pod2-stack-controller-2.localdomain | internal | enabled | down | 2017-11-16T16:08:14.000000 | - |
| 618 | nova-scheduler | pod2-stack-controller-2.localdomain | internal | enabled | down | 2017-11-16T16:08:13.000000 | - |
| 621 | nova-conductor | pod2-stack-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ecosoleauthprocess在所有控制器上運行，或使用以下命令重新啟動該進程：pcs resource restart openstack-nova-consoleauth:
[stack@director ~]$ nova service-list | grep consoleauth
| 601 | nova-consoleauth | pod2-stack-controller-0.localdomain | internal | enabled | up | 2017-11-16T21:00:10.000000 | - |
| 608 | nova-consoleauth | pod2-stack-controller-1.localdomain | internal | enabled | up | 2017-11-16T21:00:13.000000 | - |
| 622 | nova-consoleauth | pod2-stack-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@pod2-stack-controller-3 ~]# ip route
default via 10.225.247.203 dev vlan101

步驟2.檢查當前的Stonithconfiguration。刪除對舊控制器節點的任何引用：
[root@pod2-stack-controller-3 ~]# sudo pcs stonith show --full
Resource: my-ipmilan-for-controller-6 (class=stonith type=fence_ipmilan)
Attributes: pcmk_host_list=pod2-stack-controller-1 ipaddr=192.100.0.1 login=admin passwd=Csco@123Starent lanplus=1
Operations: monitor interval=60s (my-ipmilan-for-controller-6-monitor-interval-60s)
Resource: my-ipmilan-for-controller-4 (class=stonith type=fence_ipmilan)
Attributes: pcmk_host_list=pod2-stack-controller-0 ipaddr=192.100.0.14 login=admin passwd=Csco@123Starent lanplus=1
Operations: monitor interval=60s (my-ipmilan-for-controller-4-monitor-interval-60s)
Resource: my-ipmilan-for-controller-7 (class=stonith type=fence_ipmilan)
Attributes: pcmk_host_list=pod2-stack-controller-2 ipaddr=192.100.0.15 login=admin passwd=Csco@123Starent lanplus=1
Operations: monitor interval=60s (my-ipmilan-for-controller-7-monitor-interval-60s)
[root@pod2-stack-controller-3 ~]# pcs stonith delete my-ipmilan-for-controller-7
Attempting to stop: my-ipmilan-for-controller-7...Stopped
步驟3.新控制器的Addstonithconfiguration:
[root@pod2-stack-controller-3 ~]sudo pcs stonith create my-ipmilan-for-controller-8 fence_ipmilan pcmk_host_list=pod2-stack-controller-3 ipaddr=<CIMC_IP> login=admin passwd=<PASSWORD> lanplus=1 op monitor interval=60s
步驟4.從任何控制器重新啟動隔離並驗證狀態：
[root@pod2-stack-controller-1 ~]# sudo pcs property set stonith-enabled=true
[root@pod2-stack-controller-3 ~]# pcs status
<snip>
my-ipmilan-for-controller-1 (stonith:fence_ipmilan): Started pod2-stack-controller-3
my-ipmilan-for-controller-0 (stonith:fence_ipmilan): Started pod2-stack-controller-3
my-ipmilan-for-controller-3 (stonith:fence_ipmilan): Started pod2-stack-controller-3
