Dear all, I'm running LVS-DR mode on 2 X LVS. The OS is Centos 5.3, 32bit with piranha-0.8.4-11.el5. In lvs.cf, the syncdaemon = 1. But connections are not sync and I found that the multicast messages are not sent out from the MASTER LVS. In /var/log/messages, I clearly
MASTER's log: Jul 7 22:22:53 lvs1 kernel: IPVS: sync thread started: state = MASTER, mcast_ifn = eth0, syncid = 0 BACKUP's log: Jul 7 22:23:22 lvs2 kernel: IPVS: sync thread started: state = BACKUP, mcast_ifn = eth0, syncid = 0 in eth0, eth0:1, eth0:2 and eth1 of both LVS, all are showing " UP BROADCAST RUNNING MULTICAST" In the MASTER and BACKUP, I can't see any multicast message with the address 224.0.0.81, but I can see other multicast messages. [r...@lvs1 ~]# tcpdump multicast -nn tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 09:32:38.977443 IP x.x.x.x.1985 > 224.0.0.2.1985: HSRPv0-hello 20: state=active group=121 addr=x.x.x.x 09:32:39.865486 802.1d unknown version I have stopped iptables during testing so it shouldn't not be the firewall blocking the messages. Is there any clue why the multicast message is not sent out? Thanks a million.
