What OS do your various servers - directors, realservers - run? What
hardware spec are they?
I am running gentoo 2006.1 on all the servers. Hardware 4 CPU 2.80GHz
and 1 gig of Ram.
Are you including all of your IP addresses in your VRRP configs
announcements within keepalived, or are you using the
vrrp_address_excluded option to keep the announcements down to a
I am using the vrrp_address_excluded option for the ip addresses.
without looking I'd hazard a guess that you may be limited to
255 or 256 addresses per announcement, with a similar limit on the
number of VRIDs you define.
What is your config? What's the difference between a working one and a
I will post my config as an attachment if thats ok.
So many questions :)
One answer: there are no ARP issues with LVS-NAT, but you have to keep
your IP configs clean *and* keep track of your connection tables. If
you're using netfilter/iptables outbound on the director you could,
potentially, cause RAM famine by exhausting conntrack buckets. But let's
get to that slowly!
I am also using iptables on the firewall at the moment my conntrack
table is 65536 i am going to increase it now. I have also changed the
hash size with ip_conntrack.hashsize=65536 in my grub conf.
