Boa noite pessoal,

Sou novo aqui, começei a pouco tempo a mexer com linux, então antes de mais nada desculpe se não é aqui a parte em que discute sobre heartbeat.

Estou com o seguinte problema: estou configurando um cluster de alta disponibilidade, com apache e heartbeat. Quando o servidor primário para de funcionar, o secundário automaticamente assume. Até ai normal, o problema é que quando inicio novamente o primário ele não volta os serviços para o primário, o serviço continua ativo no secundário, sendo que configurei a opção de auto_failback on. Tentei encontrar caso parecido na internet, e inclusive aqui antes de postar, porém não consegui encontrar especificadamente nada sobre o este problema.

Segue abaixo os arquivos de configuração e de log:


ha.cf:


# Intervalo em segundos entre os pings
keepalive 1

#Intervalo em segundos para declarar uma maquina inativa
deadtime 4

#Tempo para notificar no log
warntime 10

#Permitir inicialização em todos os nodes
initdead 60

#Interface que fara broadcast de verificação
bcast eth0

#Configuração de nodes
node cluster01.labredes.com.br
node cluster02.labredes.com.br

#Especifica o uso de um gerenciador de recursos externo
crm off

#Porta de comunicação
udpport 694

#Volta do node primario caso haja falha e depois volte a responder
auto_failback on
nice_failback off
