更換控制器伺服器UCS C240 M4 - vEPC
目錄
簡介
本文檔介紹在託管StarOS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。
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的高級體系結構及涉及的元件如下圖所示：
UltraM體系結構
本文檔面向熟悉Cisco Ultra-M平台的思科人員，詳細介紹在更換控制器伺服器時，在OpenStack和StarOS VNF級別需要執行的步驟。

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。
- 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
- 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。

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。
- 檢查活動控制器中的MariaDB狀態：

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
- 檢查活動控制器中的Rabbitmq狀態。出現故障的控制器不應出現在正在運行的節點的清單中。
[heat-admin@pod1-controller-0 ~] sudo rabbitmqctl cluster_status

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：
- 使用CIMC IP登入到伺服器
- 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：
- 驗證物理驅動器的狀態。它必須是「Unconfigured Good」：
儲存> Cisco 12G SAS模組化Raid控制器(SLOT-HBA)>物理驅動器資訊
- 使用RAID級別1從物理驅動器建立虛擬驅動器：
儲存> Cisco 12G SAS模組化Raid控制器(SLOT-HBA)>控制器資訊>從未使用的物理驅動器建立虛擬驅動器
- 選擇VD並配置Set as Boot Drive:
- 啟用IPMI over LAN:
Admin > Communication Services > Communication Services
- 禁用超執行緒：
計算> BIOS >配置BIOS >高級>處理器配置
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
- 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
| 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 |
- 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
- 製作用於安裝覆蓋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 ~/custom-templates/network.yaml \
-e ~/custom-templates/ceph.yaml \
-e ~/custom-templates/compute.yaml \
-e ~/custom-templates/layout-removeController.yaml \

- 使用此處提到的指令，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

- 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@pod1-controller-0 ~]# sudo pcs resource unmanage galera
[root@pod1-controller-0 ~]# sudo pcs status
Cluster name: tripleo_cluster

<snip>
準備新增新控制器節點
- 建立一個controllerRMA.json檔案，其中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>"
}
]
}
- 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
- 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 |
- 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 |
- 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
- 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

- 11.119.0.10
- 11.119.0.11
- 11.119.0.12
- 11.119.0.13
- 現在，運行之前建立的deploy-removecontroller.sh，以刪除舊節點並新增新節點。

- 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。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
}
}
- 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，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
- 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@pod1-controller-0 ~]# sudo crm_node -R pod1-controller-2 --force
- 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 ...
- 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
- 使用前面命令中的IP地址和埠號登入節點並檢查其是否是主節點：
[heat-admin@pod1-controller-0 ~]$ echo "db.isMaster()" | mongo --host 11.120.0.10:27017
MongoDB shell version: 2.6.11

}
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。
- 在主目錄中，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

- 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
- 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
- 從已經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

pod1-controller-3: Success
Restarting pcsd on the nodes in order to reload the certificates...
pod1-controller-3: Success
- 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，且分配給該控制器的節點ID是序列中先前未使用的下一個編號。確保在所有3個控制器上完成此變更：
[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
}
- 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
- 從其中一個作用中控制器啟動新控制器節點：
[root@pod1-controller-1 ~]# sudo pcs cluster start pod1-controller-3
- 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
- 群集處於維護模式。禁用維護模式以啟動服務：
[root@pod1-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
- 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@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 ]
- 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

| cb4bc1ad-ac50-42e9-ae69-8a256d375136 | L3 agent | pod1-controller-1.localdomain | nova | :-) | True | neutron-l3-agent |
- 在本例中，應從路由器中移除對應於pod1-controller-2.localdomain的L3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
- 檢查L3代理的更新清單：

[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
- 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 | - |

192.0.0.0/8 dev eno1 proto kernel scope link src 192.200.0.103
- 檢查當前的stonith配置。刪除對舊控制器節點的任何引用：
[root@pod1-controller-3 ~]# sudo pcs stonith show --full
Resource: my-ipmilan-for-controller-6 (class=stonith type=fence_ipmilan)
Attributes: pcmk_host_list=pod1-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=pod1-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=pod1-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@pod1-controller-3 ~]# pcs stonith delete my-ipmilan-for-controller-7
Attempting to stop: my-ipmilan-for-controller-7...Stopped
- 為新控制器新增stonith配置：
[root@pod1-controller-3 ~]sudo pcs stonith create my-ipmilan-for-controller-8 fence_ipmilan pcmk_host_list=pod1-controller-3 ipaddr=<CIMC_IP> login=admin passwd=<PASSWORD> lanplus=1 op monitor interval=60s
- 從任何控制器重新啟動隔離並驗證狀態：
[root@pod1-controller-1 ~]# sudo pcs property set stonith-enabled=true
[root@pod1-controller-3 ~]# pcs status
<snip>
my-ipmilan-for-controller-1 (stonith:fence_ipmilan): Started pod1-controller-3
my-ipmilan-for-controller-0 (stonith:fence_ipmilan): Started pod1-controller-3
my-ipmilan-for-controller-3 (stonith:fence_ipmilan): Started pod1-controller-3
