Hi,
From testing it appears that my load balance is working.
I have LVS setup using ultramonkey and I am in the process of stress testing 2
web servers behind a LVS/DR setup.
From using apachebench (ab) I get about half of the connections fail.
Sometimes the test doesn't even complete. The testing is occurring on the LAN
of the switch. Any ideas why it would fail some of the time? I don't get
these errors if I test directly to the server IP. Some times I get:
apr_recv: No route to host (113)
Total of 1000 requests completed
ab output:
[root@zeus ~]# ab -n 10000 -c 200 http://192.168.1.71/
This is ApacheBench, Version 2.0.41-dev <$Revision: 1.141 $> apache-2.0
