Hi, all,<br>
<br>
first time poster. I recently deployed lvs (primary and backup)
with piranh and ran into few issues. I turned off the primary lvs
to see backup lvs will take over. However it does not take over
right a way seem require restart pulse. How does this fail over
works if primary goes down ? should not this be happen right a way
if primary lvs goes down ?<br>
</blockquote>
If primary goes, secondary has to take it over<br>
<br>
It depends on deadtime<br>
<br>
deadtime = n<br>
Length of time before a node is declared dead and IP
takeover occurs.<br>
<br>
lvs.cf needs to be checked together with system configuration. Look
at /var/log/messages<br>
<br>
<br>

And I have four real server- and it sees if one goes down whole
system is unavailable (httpd service). Then I restart pulse and
get the httpd service. I do not think this is right. could be
please guide me in right direction to make reliable.<br>

Do you have separate boxes for LVS directors and real server's ?
[Are you running pulse on any of the two real server's ?]<br>
<br>
check the output of ipvsadm -L -n from the active lvs server [paste
it here]<br>
