LVS linux 6.2 cluster setup

By ARG CIO ·
I have followed the HOW-TO to the letter (except I only have one real server), and I have learned an amazing amount of information about linux in the last two weeks, but it still doesn't work. here is the scenario....

I have 2 3Com (3c90x.o loaded) and piranha setup. VIP1 is 192.168.200.200 LVS1 is 192.168.200.201 LVS2 is 192.168.200.202 on the "external" addresses. Internally, I have lvs1 is 192.168.100.201 and LVS2 is 192.168.100.202. VGW(Virtual Gateway) is 192.168.100.254. RS1 is 192.168.100.101 with GW 192.168.100.254 and is running ONLY http service for this test. I am using rcp/rsh for synch, and am able to rsh and rcp on both lvs boxes.

another way to look at it..
LVS1:
Eth0 IP = 192.168.200.201
Eth0:1 IP = 192.168.200.200
Eth1 IP = 192.168.100.201
Eth1:1 IP = 192.168.100.254
Default gateway 192.168.200.1

LVS2:
Eth0 IP = 192.168.200.202
Eth0:1 IP = 192.168.200.200
Eth1 IP = 192.168.100.202
Eth1:1 IP = 192.168.100.254
Default gateway 192.168.200.1

RS1:
Eth0 IP = 192.168.100.101
Default gateway 192.168.100.254

Piranha seems to be setup correctly, and no errors given when started or applied. From both LVS I can ping all of the above addresses, and from RS1 I can ping both LVS internal addresses, "floating" gateway address, and both lvs external addresses, but nothing beyond that. I cannot ping the DNS (192.168.200.82:192.168.200.83). The only thing I haven't tried is using true external addresses with existing internal addresses. I am going to try using true external addresses, but I don't see how this will make much difference. Anyone with any knowledge, or pointers would be GREATLY appreciated.

just my 2cents: did you add your IP addresses for your network to your routing tables? Usually that's the one thing I forget when setting a new network.

I'm not sure what you mean. On the LVS? on the RS? in our router? The RS is on an internal network with the LVS' and that is it.

No other connection to "external" or real world.

FAILOVER, AND everything else seems to work for the LVS cluster EXCEPT routing! Everything I have seen says, "it automatically happens between two NICs". BS! I can get out, but it never comes back.

got a 1 year service contract with RedHat, and they were able to give me the answer.. it had to do with IP_forward.. you have to set echo 1 > /proc/sys/net/ipv4/ip_forward in your rc.local.

Thank you for answering.. but it wasn't much help..
