Eu estava trabalhando em um servidor hoje, o debian squeeze. Depois de testar isso em dois servidores de teste, adicionei uma interface de rede virtual a / etc / network / interfaces assim:
# The primary network interface
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
address 10.100.2.70
netmask 255.255.0.0
gateway 10.100.0.1
# adding this one
auto eth0:1
allow-hotplug eth0:1
iface eth0:1 inet static
address 10.100.2.77
netmask 255.255.0.0
gateway 10.100.0.1
O Keepalived está gerenciando um IP virtual na máquina
ip addr show
....
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:24:81:81:e5:54 brd ff:ff:ff:ff:ff:ff
inet 10.100.2.70/16 brd 10.100.255.255 scope global eth0
inet 10.100.2.72/32 scope global eth0
Com os novos dados de interfaces no lugar, um sudo service networking restart derrubou a rede na caixa. Com um console via iDrac, a rede não iniciava, mesmo com as novas linhas removidas do arquivo, e exigia uma reinicialização. Eu sei que poderia ter feito if-up eth0:0 , mas queria ver tudo funcionar.
Existe alguma funcionalidade do keepalived que teria causado o meu problema? As únicas mensagens de log que vejo no syslog são
Sep 30 15:48:17 pgpool01 Keepalived_vrrp: Kernel is reporting: interface eth0 DOWN
Sep 30 15:48:17 pgpool01 Keepalived_vrrp: VRRP_Instance(VI_1) Entering FAULT STATE
Sep 30 15:48:17 pgpool01 Keepalived_vrrp: VRRP_Instance(VI_1) Now in FAULT state
Como eu disse, não vi os problemas nas caixas de teste.
Qualquer dica seria útil, obrigado.
edite: adicionando o link ip e a saída ifconfig
