Need help here, thank you for replying :-)
I'm setting up a syslog cluster based on IPVS, all UDP datagrams sent
from firewall with fixed source IP and fixed source port, so
pseudo-random balancing based on client IP and port won't working. And
it seems that keepalived is not supporting One-packet scheduling
option, so I did some hacks on it after keepalived started:
1. dump LVS rules with ipvsadm -S -n > rules-vs3;
2. add --ops option;
3. restore LVS rules with ipvsadm-restore < rules-vs3;
4. dump the running LVS rules with ipvsadm -S -n
So, I got two problems here:
1. Dumped rules in step 4 above is not usable anymore, the double-dash
in --ops lost, so I can't restore rule with this dump anymore. This
must be a bug.
2. The --ops option is not working sometimes you applied the rules,
and in most of times the --ops just not working. To make it work, just
'ipvsadm-restore < rules-vs3' for plenty of times until it's working.
I haven't find the patterns make it work yet. This is lucky, I can't
get it work on second host at all.
The "not working" above means the UDP datagrams from one source IP is
sticked to one realserver, it doesn't distribute to other realservers
which --ops designed for.
So I wondering if there's some CONFIG_* options that ipvs needs, or
recent development broke the code?
Here's my hosts, both running updated Gentoo. This is the second host
that --ops doesn't work at all:
