Hello Group,
I've setup LVS/DR on RH 3.0 ES. Everything with regards to LVS is working fine
and has been for sometime. However, we ran in to some problems today deploying
a package called Spread (http://www.spread.org).
I tracked the problem down to the fact that I had setup the lo:0 inteface with
a broadcast address. The Spread package uses the broadcast address of the
network to send out packets.
Pinging the broadcast address of the network from any of the LVS Real Servers
only returned the VIP address, which makes sense since the netmask for lo:0
(VIP) was 255.255.255.255.
After removing the broadcast entry from my
/etc/sysconfig/network-scripts/ifcfg-lo:0 entry, everything "seems" to work
fine.
My question to the group: Is it ok to not to have a broadcast entry in for
lo:0? Does LVS need to have a broadcast set for it to work properly?
Thanks...
Sean
