[Linux-HA] RE: Help with setting up LVS

[Callahan, Tom]

My configuration is as follows:

--------------HA.CF------------------
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility     local0
keepalive 500ms
deadtime 10
warntime 5
initdead 30
mcast eth0 225.0.0.1 694 1 0
auto_failback off
node    lvs_n1.tessco.com
node    lvs_n2.tessco.com
respawn hacluster /usr/lib/heartbeat/ipfail

apiauth ipfail gid=haclient uid=hacluster
-------------END HA.CF-------------------

-------------HARESOURCES-----------------
lvs_n1.tessco.com       \
        ldirectord::ldirectord.cf \
        LVSSyncDaemonSwap::master \
        IPaddr2::10.20.141.240/24/eth0/10.20.141.255
------------END HARESOURCES--------------

------------LDIRECTORD.CF----------------
checktimeout=10
checkinterval=2
autoreload=no
logfile="/var/log/ldirectord.log"
logfile="local0"
quiescent=yes

virtual=1
        real=10.20.141.43:0 masq
        real=10.20.141.44:0 masq
        scheduler=rr
        persistent=600
        checktype=connect
----------END LDIRECTORD.CF--------------

In my iptables configuration, I have the following:
iptables -t mangle -A PREROUTING -d 10.20.141.240 -p tcp -m tcp -j MARK
--set-mark 1

When I start everything up, I can connect to port 1400 on the director, but
the director does not pass it through to the real-servers. The connection
just sits there and timesout eventually.

Thanks,
Tom Callahan

fwmark sounds like the way to go to me. Could you give some more
information on what you have set up, and what isn't working.
