primeiro obrigado pelo seu tempo.
Estou tendo um problema com ldirectord que não consigo resolver, comento minha situação:
Eu tenho dois nós com o pacemaker e o corosync e configure alguns recursos:

O problema é no ipvsadm mostrar apenas um IP real, quando eu configurei dois agora, mostro o ldirector.cf:
root@ldap1:/home/mamartin# ipvsadm

e nos logs não vejo nada claro:

não sabe se isso é um bug ou um erro de configuração, alguém pode ajudar?
Cumprimentos.
Mesmo problema após a atualização dos servidores i386 do kernel 2.6.32 e 1.25 ipvadm para o kernel 3.2.0 e 1.26 ipvadm, enquanto o ipvsadm mostra oly one / proc / net / ip_vs mostra todos os servidores reais.
Em um amd64 recém-instalado, tudo está funcionando bem.
Para resolver o problema, apliquei o patch postado aqui link e discutido aqui link
