Dear all,
I have a problem with my lvs and fos.
Here is my lvs.cf:
===================
primary = 10.0.0.41
service = fos
rsh_command = rsh
backup_active = 0
backup = 10.0.0.42
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = nat
nat_router = 10.0.1.254 eth1:0
failover web {
address = 10.0.0.38 eth0:0
active = 1
port = 80
timeout = 6
send = "GET / HTTP/1.0\r\n\r\n"
expect = "HTTP"
start_cmd = "/etc/rc.d/init.d/httpd start"
stop_cmd = "/etc/rc.d/init.d/httpd stop"
}
virtual gretel {
active = 1
address = 10.0.0.38 eth0:0
port = 80
send = "GET / HTTP/1.0\r\n\r\n"
expect = "HTTP"
load_monitor = uptime
scheduler = wrr
protocol = tcp
timeout = 6
reentry = 15
server gretel3 {
address = 10.0.1.3
active = 1
weight = 2
}
server gretel4 {
address = 10.0.1.4
active = 1
weight = 1
}
}
=======================
Here is the log file for primary node:

Here is the log file for backup node:
=======================
Oct 23 11:21:10 gretelf fos[15505]: Starting local service 10.0.0.38:80
...
Oct 23 11:21:10 gretelf fos[15505]: running command
"/etc/rc.d/init.d/httpd" "start"
Oct 23 11:21:10 gretelf httpd: httpd startup succeeded
Oct 23 11:21:13 gretelf pulse[15421]: Notifying partner WE are taking
control!
Oct 23 11:21:15 gretelf pulse[15504]: gratuitous fos arps finished
========================
1) Why when I startup the pulse at backup node, it straight away become
active and the primary node become inactive??
2) After that, I cannot access the VIP address via a client. But, when I
use "ps axw" on both primary and backup nodes, there is only pulse
running on primary node. Here is the
backup"ps axw":
=================
15421 ? S 0:00 pulse
15505 ? S 0:00 /usr/sbin/fos --active -c /etc/lvs.cf
--nofork
15531 ? S 0:00 httpd
15534 ? S 0:00 httpd
15535 ? S 0:00 httpd
15536 ? S 0:00 httpd
15537 ? S 0:00 httpd
15538 ? S 0:00 httpd
15539 ? S 0:00 httpd
15540 ? S 0:00 httpd
15541 ? S 0:00 httpd
3) Furthermore, it seems that the httpd on primary node is stopped. Why
is this happen?
4) I also try to unplug the primary node from the Internet, the backup
node is failover. But, when I plugged the primary node back to the
Internet, the primary node doesn't seem to failover. The primary node
still is inactive wheareas the backup node is active. Pls advice.
Thank you.
Don't worry, Be happy! :)
