备份
在恢复的情况下， Cisco推荐使用OSPD数据库(DB)的备份与使用这些步骤：
[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
初步的状态检查
请注意检查OpenStack环境和服务的当前状态和它是健康的，在您继续进行替换程序前。它可帮助在控制器替换过程时避免复杂化。
- 检查OpenStack和节点列表的状况：
[stack@director ~]$ source stackrc
[stack@director ~]$ openstack stack list --nested
[stack@director ~]$ ironic node-list
[stack@director ~]$ nova list
- 检查在控制器的心脏起搏器状态：
登陆到其中一个激活控制器并且检查心脏起搏器状态。所有服务在发生故障的控制器应该运作在可用的控制器和终止。

安装新的控制器节点
- 步骤为了安装一个新的UCS C240 M4服务器和初始建立步骤可以参考从：
- 服务器的洛金有使用的CIMC IP
- 如果固件不是根据以前，使用的推荐的版本请执行BIOS升级。测量得BIOS升级的步骤这里：
- 验证物理驱动的状况。这一定是“没有配置好” ：
存贮> Cisco 12G SAS模块化袭击控制器(SLOT-HBA) >物理驱动信息
- 用RAID第1级创建从物理驱动的一个虚拟驱动器：
存贮> Cisco 12G SAS模块化袭击控制器(SLOT-HBA) >控制器信息>创建从未使用的物理驱动的虚拟驱动器
- 选择VD并且配置集作为引导驱动器：
- 在LAN的Enable (event) IPMI ：
Admin >通信服务>通信服务
- hyperthreading的功能失效：
估计> BIOS >配置BIOS >Advanced >处理器配置
控制器节点更换乌云密布
此部分包括要求为了用在乌云密布的新的替换有故障的控制器的步骤。对于此，使用提出堆栈将重新使用的deploy.sh脚本。 在配置时，在ControllerNodesPostDeployment阶段，更新失效由于一些限制木偶模块。人工干预，在您重新启动配置脚本前，需要。
准备删除发生故障的控制器节点
- 识别发生故障的控制器的索引。索引是在控制器名字的数字后缀在OpenStack服务器列表输出中。在本例中，索引是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 |
- 创建将定义节点删除的一个Yaml文件~templates/remove-controller.yaml。请使用被找到的索引在上一步在资源列表的条目：
[stack@director ~]$ cat templates/remove-controller.yaml
parameters:
ControllerRemovalPolicies:
[{'resource_list': [‘2’]}]
parameter_defaults:
CorosyncSettleTries: 5
- 做使用为了安装乌云密布和插入线路为了包含以前被创建的去除controller.yaml文件的复制配置脚本：
[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 \

<snip>
准备添加新的控制器节点
- 用仅新的控制器详细资料创建一个controllerRMA.json文件。保证以前未使用在新的控制器的索引编号。 一般，对下个高控制器编号的增量。
示例：最高预先是Controller-2，因此请创建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>"
}
]
}
- 导入与在上一步创建的使用的新节点json文件：
[stack@director ~]$ openstack baremetal import --json controllerRMA.json

[stack@director ~]$ openstack baremetal node list | grep available
| 048ccb59-89df-4f40-82f5-3d90d37ac7dd | None | None | power off | available | False
- 设置节点管理状态：
[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 | available | False |
- 标记可用的节点用新的控制器属性。保证使用如用于controllerRMA.json文件被选定的新的控制器，控制器ID ：
[stack@director ~]$ openstack baremetal node set --property capabilities='node:controller-3,profile:control,boot_option:local' 048ccb59-89df-4f40-82f5-3d90d37ac7dd
- 在配置脚本，有称为尤其，指定的layout.yaml的自定义模板什么IP地址分配到控制器为多种接口。在一个新的堆栈，有为Controller-0、Controller-1和Controller-2定义的3个地址。当您添加一个新的控制器时，请保证您为每个子网依顺序添加一个下个IP地址：
ControllerIPs:
internal_api:

人工干预
- 在OSP-D服务器上，请运行list命令OpenStack的服务器为了列出可用的控制器。新加的控制器应该出现于列表：
[stack@director ~]$ openstack server list | grep controller
| 3e6c3db8-ba24-48d9-b0e8-1e8a2eb8b5ff | pod1-controller-3 | ACTIVE | ctlplane=192.200.0.103 | overcloud-full |

- 登陆对其中每一个激活控制器。删除发生故障的节点并且重新启动服务。在这种情况下，请去除pod1-controller-2。请勿进行对新加的控制器的此动作：
[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
- 从其中一个激活控制器运行此命令为了从簇删除发生故障的节点：
[root@pod1-controller-0 ~]# sudo crm_node -R pod1-controller-2 --force
- 从其中一个激活控制器运行此命令为了从rabbitmq簇删除发生故障的节点：
[root@pod1-controller-0 ~]# sudo rabbitmqctl forget_cluster_node rabbit@pod1-controller-2
Removing node 'rabbit@newtonoc-controller-2' from cluster ...
- 从MongoDB删除发生故障的节点。为了执行此，您需要查找活动蒙戈币节点。请使用netstat查找主机的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
- 登陆对节点并且检查为了发现它是否是与使用的主设备IP地址和端口号从前面的命令：
[heat-admin@pod1-controller-0 ~]$ echo "db.isMaster()" | mongo --host 11.120.0.10:27017

- 运行此命令为了更新激活控制器节点列表。包括新的控制器节点在此列表：
[root@pod1-controller-0 ~]# sudo pcs resource update galera wsrep_cluster_address=gcomm://pod1-controller-0,pod1-controller-1,pod1-controller-2
- 从已经存在到新的控制器的控制器复制这些文件：
/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
- 从已经存在的其中一个控制器运行add命令的簇结：
[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-3: Success
- 登陆到每个控制器并且查看文件/etc/corosync/corosync.conf。 保证新的控制器是列出的，并且节点ID分配到该控制器是在以前未使用的顺序的下个编号。保证此更改在所有3个控制器完成：
[root@pod1-controller-1 ~]# cat /etc/corosync/corosync.conf
totem {

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 {

nodeid: 6
}
}
quorum {
provider: corosync_votequorum
}
logging {
to_logfile: yes
logfile: /var/log/cluster/corosync.log
to_syslog: yes
}
例如/etc/corosync/corosync.conf在修改以后：
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
}
- 在激活控制器的重新启动corosync。请勿开始在新的控制器的corosync ：
[root@pod1-controller-0 ~]# sudo pcs cluster reload corosync
[root@pod1-controller-1 ~]# sudo pcs cluster reload corosync
- 启动新的控制器节点从其中一个代理控制器：
[root@pod1-controller-1 ~]# sudo pcs cluster start pod1-controller-3
- 重新启动从其中一个的加莱拉角代理控制器：
[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

[root@pod1-controller-1 ~]#
[root@pod1-controller-1 ~]# sudo pcs resource manage galera
- 簇在维护模式下。禁用维护模式为了使服务开始：
[root@pod1-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
- 请检查个人计算机状态加莱拉角，直到全部3个控制器列出作为主设备在加莱拉角：
[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 ]
- 换成簇维护模式：
[root@pod1-controller-1~]# sudo pcs property set maintenance-mode=true --wait
[root@pod1-controller-1 ~]# pcs cluster status
