更换控制器服务器UCS C240 M4 - CPAR
目录
简介
本文档介绍在Ultra-M设置中更换故障控制器服务器所需的步骤。
此过程适用于使用NEWTON版本的OpenStack环境，其中弹性服务控制器(ESC)不管理Cisco Prime Access Registrar(CPAR)，并且CPAR直接安装在OpenStack上部署的VM上。
背景信息
Ultra-M是经过预封装和验证的虚拟化移动数据包核心解决方案，旨在简化VNF的部署。OpenStack是Ultra-M的虚拟化基础设施管理器(VIM)，由以下节点类型组成：
- 计算
- 对象存储磁盘 — 计算（OSD — 计算）
- 控制器
- OpenStack平台 — 导向器(OSPD)
Ultra-M的高级体系结构和所涉及的组件如下图所示：
本文档面向熟悉Cisco Ultra-M平台的思科人员，并详细介绍在OpenStack和Redhat OS中执行所需的步骤。

先决条件
备份
在恢复时，思科建议使用以下步骤备份OSPD数据库(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
初步状态检查
在您继续执行更换过程之前，必须检查OpenStack环境和服务的当前状态并确保其正常运行。它有助于避免控制器更换过程中出现问题。
步骤1.检查OpenStack和节点列表的状态：
[stack@director ~]$ source stackrc
[stack@director ~]$ openstack stack list --nested
[stack@director ~]$ ironic node-list
[stack@director ~]$ nova list
步骤2.检查控制器上的Pacemaker状态：
登录其中一个活动控制器并检查起搏器状态。所有服务都应在可用控制器上运行，并在故障控制器上停止。
[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
在本例中，控制器2处于脱机状态。因此，它被替换了。控制器0和控制器1运行正常，并运行集群服务。
步骤3.检查活动控制器中的MariaDB状态：
[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
验证每个活动控制器都存在以下线路：
wsrep_local_state_comment:已同步
wsrep_cluster_size:2
步骤4.检查活动控制器中的Rabbitmq状态。故障控制器不应出现在运行的节点列表中。
[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',[]}]}]
步骤5.检查OSP-D节点中是否所有下云服务都处于加载、活动和运行状态。
[stack@director ~]$ systemctl list-units "openstack*" "neutron*" "openvswitch*"

安装新控制器节点
安装新UCS C240 M4服务器的步骤和初始设置步骤可从以下位置参考：Cisco UCS C240 M4服务器安装和服务指南
步骤1.使用CIMC IP登录服务器。
步骤2.如果固件与之前使用的推荐版本不同，则执行BIOS升级。BIOS升级步骤如下：Cisco UCS C系列机架式服务器BIOS升级指南
步骤3.要验证物理驱动器的状态(未配置良好)，请导航到存储> Cisco 12G SAS模块化RAID控制器(SLOT-HBA)>物理驱动器信息，如图所示。
步骤4.要从RAID级别为1的物理驱动器创建虚拟驱动器，请导航到Storage > Cisco 12G SAS模块化RAID控制器(SLOT-HBA)> Controller Info > Create Virtual Drive from Unused Physical Drives。
- 选择VD并配置Set as Boot Drive:
步骤5.要启用IPMI over LAN，请导航至Admin > Communication Services > Communication Services。
步骤6.要禁用超线程，请导航至Compute > BIOS > Configure BIOS > Advanced > Processor Configuration。
在Overcloud中更换控制器节点
本节介绍将故障控制器替换为超云中的新控制器所需的步骤。为此，将重新使用用于启动堆栈的deploy.shscript。在部署时，在“控制器节点部署后”阶段，由于Puppet模块中的某些限制，更新将失败。重新启动部署脚本之前需要手动干预。
准备删除故障控制器节点
步骤1.确定故障控制器的索引。索引是OpenStack服务器列表输出中控制器名称上的数字后缀。在本例中，索引为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 |
步骤2.创建一个Yaml文件~templates/remove-controller.yaml，该文件将定义要删除的节点。使用上一步中找到的索引查找资源列表中的条目：
[stack@director ~]$ cat templates/remove-controller.yaml
parameters:
ControllerRemovalPolicies:
[{'resource_list': [‘2’]}]
parameter_defaults:
CorosyncSettleTries: 5
步骤3.制作部署脚本的副本，以安装超云并插入一行，以包括之前创建的themove-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_$(date +%m_%d_%y__%H_%M_%S).log \
--neutron-flat-networks phys_pcie1_0,phys_pcie1_1,phys_pcie4_0,phys_pcie4_1 \
--neutron-network-vlan-ranges datacentre:101:200 \
--neutron-disable-tunneling \
--verbose --timeout 180
步骤4.使用此处提到的命令确定要更换的控制器的ID，并将其移至维护模式：
[stack@director ~]$ 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 |
步骤5.为确保数据库在更换过程中运行，请从起搏器控制中删除Galera，并在其中一个主用控制器上运行此命令：
[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>
准备添加新控制器节点
步骤1.仅使用新的控制器详细信息创建controllerRMA.jsonfile。确保新控制器上的索引号以前未使用过。 通常，递增到下一个最高控制器编号。
示例：最早的是控制器2，因此创建控制器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>"
}
]
}
步骤2.使用上一步骤中创建的json文件导入新节点：
[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
步骤3.将节点设置为管理状态：
[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 |
步骤4.运行内省：
[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 |
步骤5.使用新的控制器属性标记可用节点。确保使用为新控制器指定的控制器ID，如controllerRMA.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
步骤6.在部署脚本中，有一个自定义模板ledlayout.yaml，该模板除其他内容外，还指定为各种接口的控制器分配了哪些IP地址。在新堆栈中，为控制器0、控制器1和控制器2定义了3个地址。在添加新控制器时，请确保按顺序为每个子网添加下一个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
步骤7.现在运行以前创建的deploy-removecontroller.sh，以删除旧节点并添加新节点。
[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']

手动干预
步骤1.在OSP-D服务器上，运行OpenStack server list命令以列出可用的控制器。新添加的控制器应出现在列表中：
[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 |
步骤2.连接到其中一个活动控制器（而不是新添加的控制器）并查看文件/etc/corosync/corosycn.conf。查找为每个控制器分配anodeid的nodelist。查找失败节点的条目并注意其snodeid:
[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
}
}
步骤3.登录到每个活动控制器。删除故障节点并重新启动服务。在这种情况下，请removepod2-stack-controller-2。请勿在新添加的控制器上执行此操作：
[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
步骤4.从其中一个活动控制器运行此命令，以便从群集中删除故障节点：
[root@pod2-stack-controller-0 ~]# sudo crm_node -R pod2-stack-controller-2 --force
步骤5.从其中一个活动控制器运行此命令，以便从therabbitmqcluster中删除故障节点：
[root@pod2-stack-controller-0 ~]# sudo rabbitmqctl forget_cluster_node rabbit@pod2-stack-controller-2
Removing node 'rabbit@newtonoc-controller-2' from cluster ...
步骤6.从MongoDB中删除故障节点。为此，您需要找到活动的Mongo节点。Usenetstat查找主机的IP地址：
[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
步骤7.登录到节点并检查是否是使用上一命令中的IP地址和端口号的主节点：
[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
{
"setName" : "tripleo",
"setVersion" : 9,
"ismaster" : true,
"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
}
如果节点不是主节点，请登录到其他活动控制器并执行相同步骤。
步骤1.从主设备中，使用thers.status()命令列出可用节点。查找旧节点/无响应节点并标识mongo节点名称。
[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
}
步骤2.从主设备中，使用thers.removecommand删除故障节点。执行此命令时会看到一些错误，但再次检查状态，以查找节点已被删除：
[root@pod2-stack-controller-0 ~]$ mongo --host 11.120.0.10
<snip>

],
"ok" : 1
}
tripleo:PRIMARY> exit
bye
步骤3.运行此命令以更新活动控制器节点列表。在此列表中包括新控制器节点：
[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
步骤4.将这些文件从已存在的控制器复制到新控制器：
/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
步骤5.从已存在的控制器之一运行cluster node add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
步骤6.登录到每个控制器并查看文件/etc/corosync/corosync.conf。确保列出新控制器，并且分配给该控制器的节点是序列中以前未使用的下一个编号。确保在所有3个控制器上完成此更改：
[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
}
步骤7.重新启动活动控制器。请勿启动新控制器的同步：
[root@pod2-stack-controller-0 ~]# sudo pcs cluster reload corosync
[root@pod2-stack-controller-1 ~]# sudo pcs cluster reload corosync
步骤8.从一个作用控制器启动新控制器节点：
[root@pod2-stack-controller-1 ~]# sudo pcs cluster start pod2-stack-controller-3
步骤9.从一个代理控制器重新启动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
步骤10.集群处于维护模式。禁用维护模式以启动服务：
[root@pod2-stack-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
步骤11.检查PC的Galera状态，直到3个控制器全部列为Galera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 ]
步骤12.将集群切换到维护模式：
[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

最终确定L3代理路由器
检查路由器以确保L3代理正确托管。执行此检查时，请确保源到overcloudrc文件。
步骤1.查找路由器名称：
[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 |
在本例中，路由器的名称是main。
步骤2.列出所有L3代理，以查找故障节点和新节点的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 |
在本示例中，应从路由器中删除与pod2-stack-controller-2.localdomain对应的L3代理，并应将与pod2-stack-controller-3.localdomain对应的代理添加到路由器：
[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
步骤3.检查更新的L3代理列表：
[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 |
+--------------------------------------+-----------------------------------+----------------+-------+----------+
步骤4.列出从已删除的控制器节点运行的所有服务并删除它们：
[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 ~]$
最终确定计算服务
步骤1.从删除的节点中保留的Checknova服务列表项并删除它们：
[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
步骤2.确保consoleauthprocess在所有控制器上运行，或使用以下命令重新启动它：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 | -
在控制器节点上重新启动隔离
步骤1.检查所有控制器以查找通向下云192.0.0.0/8的IP路由：
[root@pod2-stack-controller-3 ~]# ip route
default via 10.225.247.203 dev vlan101
10.225.247.128/25 dev vlan101 proto kernel scope link src 10.225.247.212
11.117.0.0/24 dev vlan17 proto kernel scope link src 11.117.0.10
11.118.0.0/24 dev vlan18 proto kernel scope link src 11.118.0.10
11.119.0.0/24 dev vlan19 proto kernel scope link src 11.119.0.10
11.120.0.0/24 dev vlan20 proto kernel scope link src 11.120.0.10
169.254.169.254 via 192.200.0.1 dev eno1
192.200.0.0/24 dev eno1 proto kernel scope link src 192.200.0.113
步骤2.检查当前的配置。删除对旧控制器节点的任何引用：
[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

步骤3.新控制器的附加配置：
[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
步骤4.从任何控制器重新启动隔离并验证状态：
[root@pod2-stack-controller-1 ~]# sudo pcs property set stonith-enabled=true
[root@pod2-stack-controller-3 ~]# pcs status
