Binary package hint: keepalived
The actual version (1.1.17) of keepalived in Ubuntu 9.10-amd64 have a big problem,
silently the package was build without the LVS support so if you put some
configuration dedicated to balance some servers, the keepalived daemon simply
ignore it without any warning.
This is a big problem because no warning and no information about this
change wasn't present...
This is my configuration:
cat /etc/keepalived/keepalived.conf
global_defs {
notification_email {
keepalived-oper
}
notification_email_from keepalived-oper
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id FWLVS1
}
vrrp_instance VI_OUT {
interface ethOUT
state MASTER
virtual_router_id 9
priority 250
authentication {
auth_type AH
auth_pass keep
}
virtual_ipaddress {
172.22.100.9/24
172.22.100.12/24
172.22.100.13/24
}
preempt_delay 300
}
virtual_server 172.22.100.12 80 {
delay_loop 10
lb_algo wlc
lb_kind NAT
persistence_timeout 120
persistence_granularity 255.255.0.0
protocol TCP
quorum 1
real_server 192.168.69.20 80 {
weight 1
TCP_CHECK {
connect_port 80
connect_timeout 3
}
}
real_server 192.168.69.21 80 {
weight 1
TCP_CHECK {
connect_port 80
connect_timeout 3
}
}
}
if i run the daemon with the --dump config this is the output:

As You can see the LVSpart was completly ignored, no warning, no message, nothing!
Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!
