Substituição do servidor controlador UCS C240 M4 - CPAR
Contents
Introdução
Este documento descreve as etapas necessárias para substituir um servidor de controlador com defeito em uma configuração Ultra-M.
Este procedimento se aplica a um ambiente Openstack usando a versão NEWTON, onde o Elastic Services Controller (ESC) não gerencia o Cisco Prime Access Registrar (CPAR) e o CPAR é instalado diretamente na VM implantada no Openstack.
Informações de Apoio
A Ultra-M é uma solução de núcleo de pacotes móveis virtualizados, validada e predefinida, projetada para simplificar a implantação de VNFs. O OpenStack é o Virtualized Infrastructure Manager (VIM) para Ultra-M e consiste nos seguintes tipos de nó:
- Computação
- Disco de armazenamento de objetos - Computação (OSD - Computação)
- Controlador
- Plataforma OpenStack - Diretor (OSPD)
A arquitetura avançada do Ultra-M e os componentes envolvidos são mostrados nesta imagem:
Este documento destina-se ao pessoal da Cisco que está familiarizado com a plataforma Cisco Ultra-M e detalha as etapas que devem ser executadas no OpenStack e no Redhat OS.

Pré-requisitos
Fazer backup
Em caso de recuperação, a Cisco recomenda fazer um backup do banco de dados (DB) do OSPD com o uso destas etapas:
[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
Verificação preliminar de status
É importante verificar o status atual do ambiente e dos serviços do OpenStack e garantir que ele esteja íntegro antes de continuar com o procedimento de substituição. Ele pode ajudar a evitar complicações no momento do processo de substituição do controlador.
Etapa 1. Verifique o status do OpenStack e a lista de nós:
[stack@director ~]$ source stackrc
[stack@director ~]$ openstack stack list --nested
[stack@director ~]$ ironic node-list
[stack@director ~]$ nova list
Etapa 2. Verificar o status do Pacemaker nos controladores:
Faça login em um dos controladores ativos e verifique o status do pacemaker. Todos os serviços devem ser executados nos controladores disponíveis e interrompidos no controlador com falha.
[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
Neste exemplo, Controller-2 está offline. É, por conseguinte, substituído. O Controller-0 e o Controller-1 estão operacionais e executam os serviços de cluster.
Etapa 3. Verificar o status do MariaDB nas controladoras ativas:
[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
Verifique se estas linhas estão presentes para cada controlador ativo:
wsrep_local_state_comment: Sincronizado
wsrep_cluster_size: 2
Etapa 4. Verifique o status de Rabbitmq nos controladores ativos. O controlador com falha não deve aparecer na lista dos nós que são executados.
[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',[]}]}]
Etapa 5. Verifique se todos os serviços em nuvem estão carregados, ativos e em execução no nó OSP-D.
[stack@director ~]$ systemctl list-units "openstack*" "neutron*" "openvswitch*"

Substituição de nó de controlador em Overcloud
Esta seção aborda as etapas necessárias para substituir o controlador defeituoso pelo novo no overcloud. Para isso, o deploy.shscript que foi usado para ativar a pilha seria reutilizado. No momento da implantação, na fase de Pós-implantação dos Nós do Controlador, a atualização falharia devido a algumas limitações nos módulos Puppet. A intervenção manual é necessária antes de você reiniciar o script de implantação.
Prepare para remover o nó de controlador com falha
Etapa 1. Identificar o índice da controladora que falhou. O índice é o sufixo numérico no nome do controlador na saída da lista do servidor OpenStack. Neste exemplo, o índice é 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 |
Etapa 2. Crie um arquivo Yaml~templates/remove-controller.yamlque defina o nó a ser excluído. Use o índice encontrado na etapa anterior para a entrada na lista de recursos:
[stack@director ~]$ cat templates/remove-controller.yaml
parameters:
ControllerRemovalPolicies:
[{'resource_list': [‘2’]}]
parameter_defaults:
CorosyncSettleTries: 5
Etapa 3. Faça uma cópia do script de implantação que é usado para instalar o overcloud e insira uma linha para incluir theremove-controller.yamlfile criado anteriormente:
[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 ~/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 \

--neutron-network-vlan-ranges datacentre:101:200 \
--neutron-disable-tunneling \
--verbose --timeout 180
Etapa 4. Identifique o ID da controladora a ser substituída, com o uso dos comandos mencionados aqui, e mova-o para o modo de manutenção:
[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 |
Etapa 5. Para garantir que o DB seja executado no momento do procedimento de substituição, remova o Galera do controle do marca-passo e execute este comando em um dos controladores ativos:
[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>
Prepare-se para adicionar novo nó de controlador
Etapa 1. Crie um controllerRMA.jsonfile somente com os detalhes do novo Controlador. Verifique se o número de índice no novo Controlador não foi usado antes. Normalmente, incremente para o próximo número de controlador mais alto.
Exemplo: A maior prioridade anterior era Controller-2, portanto, crie 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>"
}
]
}
Etapa 2. Importe o novo nó com o uso do arquivo json criado na etapa anterior:
[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
Etapa 3. Definir o nó para gerenciar o estado:
[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 |
Etapa 4. Executar introspecção:
[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 |
Etapa 5. Marque o nó disponível com as novas propriedades do controlador. Certifique-se de usar a ID do controlador designada para o novo controlador, conforme usada no arquivo controllerRMA.json:
[stack@director ~]$ openstack baremetal node set --property capabilities='node:controller-3,profile:control,boot_option:local' 048ccb59-89df-4f40-82f5-3d90d37ac7dd
Etapa 6. No script de implantação, há um modelo personalizado chamado layout.yaml que, entre outras coisas, especifica quais endereços IP são atribuídos aos controladores para as várias interfaces. Em uma nova pilha, há 3 endereços definidos para Controller-0, Controller-1 e Controller-2. Ao adicionar um novo controlador, assegure-se de adicionar um próximo endereço IP em sequência para cada sub-rede:
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
Etapa 7. Agora, execute o deploy-removecontroller.shque foi criado anteriormente para remover o nó antigo e adicionar o novo nó.
[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']

Etapa 1. No servidor OSP-D, execute o comando de listagem do servidor OpenStack para listar os controladores disponíveis. A controladora recém-adicionada deve aparecer na lista:
[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 |
Etapa 2. Conecte-se a uma das controladoras ativas (não à controladora recém-adicionada) e examine o arquivo/etc/corosync/corosycn.conf. Localize a lista que atribui anodeida cada controladora. Localize a entrada do nó com falha e observe 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
}
}
Etapa 3. Efetue login em cada um dos controladores ativos. Remova o nó com falha e reinicie o serviço. Nesse caso, removepod2-stack-controller-2. Não execute esta ação no controlador recém-adicionado:
[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
Etapa 4. Execute este comando a partir de um dos controladores ativos para excluir o nó com falha do cluster:
[root@pod2-stack-controller-0 ~]# sudo crm_node -R pod2-stack-controller-2 --force
Etapa 5. Execute este comando a partir de um dos controladores ativos para excluir o nó com falha do therabbitmqcluster:
[root@pod2-stack-controller-0 ~]# sudo rabbitmqctl forget_cluster_node rabbit@pod2-stack-controller-2
Removing node 'rabbit@newtonoc-controller-2' from cluster ...
Etapa 6. Exclua o nó com falha do MongoDB. Para fazer isso, você precisa encontrar o nó Mongo ativo. Usenetstatpara localizar o endereço IP do 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
Etapa 7. Efetue login no nó e verifique se ele é o mestre com o uso do endereço IP e do número de porta do comando anterior:
[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
{

],
"primary" : "11.120.0.10:27017",

"maxWriteBatchSize" : 1000,
"localTime" : ISODate("2017-11-16T18:36:34.473Z"),
"maxWireVersion" : 2,
"minWireVersion" : 0,
"ok" : 1
}
Se o nó não for o mestre, faça login no outro controlador ativo e execute a mesma etapa.
Etapa 1. No mestre, liste os nós disponíveis com o uso do comando thers.status(). Localize o nó antigo/sem resposta e identifique o nome do nó mongo.
[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

}
],
"ok" : 1
}
Etapa 2. No mestre, exclua o nó com falha usando thers.removecommand. Alguns erros são vistos quando você executa esse comando, mas verifique o status mais uma vez para descobrir que o nó foi removido:
[root@pod2-stack-controller-0 ~]$ mongo --host 11.120.0.10

bye
Etapa 3. Execute este comando para atualizar a lista de nós do controlador ativo. Inclua o novo nó controlador nesta lista:
[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
Etapa 4. Copie esses arquivos de uma controladora que já existe para a nova controladora:
/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
Etapa 5. Execute o comando cluster node addde um dos controladores que já existe:
[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
Etapa 6. Efetue login em cada controlador e visualize o arquivo/etc/corosync/corosync.conf. Verifique se o novo controlador está listado e se o nó atribuído a esse controlador é o próximo número na sequência que não foi usado anteriormente. Certifique-se de que essa alteração seja feita em todos os três controladores:
[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
}
Por exemplo/etc/corosync/corosync.confafter modificação:
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
}
Etapa 7. Reinicializarcorosyncon nos controladores ativos. Não inicieCorsyncon na nova controladora:
[root@pod2-stack-controller-0 ~]# sudo pcs cluster reload corosync
[root@pod2-stack-controller-1 ~]# sudo pcs cluster reload corosync
Etapa 8. Inicie o novo nó do controlador a partir de um dos controladores atuantes:
[root@pod2-stack-controller-1 ~]# sudo pcs cluster start pod2-stack-controller-3
Etapa 9. Reinicie o Galera a partir de um dos controladores atuantes:
[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
Etapa 10. O cluster está no modo de manutenção. Desative o modo de manutenção para iniciar os serviços:
[root@pod2-stack-controller-2 ~]# sudo pcs property set maintenance-mode=false --wait
Etapa 11. Verifique o status dos PCs do Galera até que todos os 3 controladores estejam listados como mestres no Galera:
[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 ]
Etapa 12. Mudar o cluster para o modo de manutenção:
[root@pod2-stack-controller-1~]# sudo pcs property set maintenance-mode=true --wait
[root@pod2-stack-controller-1 ~]# pcs cluster status
Cluster Status:

[heat-admin@pod2-stack-controller-2 ~]$ sudo pcs status
Finalizar os Roteadores do Agente L3
Verifique os roteadores para garantir que os agentes L3 estejam hospedados corretamente. Certifique-se de originar o arquivo overcloudrc ao executar esta verificação.
Etapa 1. Localizar o nome do roteador:
[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 |
Neste exemplo, o nome do roteador é main.
Etapa 2. Liste todos os agentes L3 para localizar o UUID do nó com falha e do novo nó:
[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 |
Neste exemplo, o agente L3 que corresponde a pod2-stack-controller-2.localdomaindeve ser removido do roteador e o que corresponde a pod2-stack-controller-3.localdomaindeve ser adicionado ao roteador:
[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
Etapa 3. Verificar a lista atualizada de agentes L3:
[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 |
+--------------------------------------+-----------------------------------+----------------+-------+----------+
Etapa 4. Liste todos os serviços que são executados a partir do nó do controlador removido e remova-os:
[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 |

Deleted agent(s): a58a3dd3-4cdc-48d4-ab34-612a6cd72768
[stack@director ~]$ neutron agent-list | grep controller-2
[stack@director ~]$
Finalizar serviços de computação
Etapa 1. Verifique os itens de lista de serviço restantes do nó removido e exclua-os:
[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 | - |

[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
Etapa 2. Certifique-se de que o processo deconsoleauthseja executado em todas as controladoras ou reinicie-o com o uso deste comando:pcs resource restart openstack-nova-consoleauth:
[stack@director ~]$ nova service-list | grep consoleauth

Reiniciar o zoneamento nos nós do controlador
Etapa 1. Verificar todos os controladores de rota IP para o undercloud 192.0.0.0/8:
[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
Etapa 2. Verifique a configuração atual. Remova qualquer referência ao nó de controlador antigo:
[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
Etapa 3. Addstonithconfiguration para o novo controlador:
[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
Etapa 4. Reinicie o zoneamento a partir de qualquer controlador e verifique o status:
[root@pod2-stack-controller-1 ~]# sudo pcs property set stonith-enabled=true
[root@pod2-stack-controller-3 ~]# pcs status
<snip>
