How do you do NFS the howto is a bit vague ?
Eventualy I'd like two heads on sharred storage...
I've done a :
/usr/sbin/iptables -t mangle -A PREROUTING -p udp -d 1.1.1.11 -j MARK
--set-mark 1
/usr/sbin/iptables -t mangle -A PREROUTING -p tcp -d 1.1.1.11 -j MARK
--set-mark 1
And set up a FWM VIP 1 with one real server and 300 persistence
>From the client I get :
# mount 1.1.1.11:/mail /tests2
[udp] 1.1.1.11:/mail: NFSPROC_NULL: RPC: Timed out
Log from the loadbalancer:
root@lbmaster:/sbin# tcpdump -i eth0 -n src or dst 1.1.1.5
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

UDP 04:48 UDP 1.1.1.5:985 1.1.1.11:111 1.1.1.3:111
By the way, working connection (i.e. not load balanced) looks as following:

Any ideas appreciated.
