<div class="moz-cite-prefix">Ok...after some testing it seems like
the new 3.4 servers are dropping (or at least not getting)
multicast packets:<br>
<br>
Here is a test between two 3.4 proxmox servers:<br>
<br>
root@proxmox3:~# asmping 224.0.2.1 proxmox1.npr.org<br>
asmping joined (S,G) = (*,224.0.2.234)<br>
pinging 172.31.2.141 from 172.31.2.33<br>
unicast from 172.31.2.141, seq=1 dist=0 time=1.592 ms<br>
unicast from 172.31.2.141, seq=2 dist=0 time=0.163 ms<br>
unicast from 172.31.2.141, seq=3 dist=0 time=0.136 ms<br>
unicast from 172.31.2.141, seq=4 dist=0 time=0.117 ms<br>
........<br>
<br>
--- 172.31.2.141 statistics ---<br>
11 packets transmitted, time 10702 ms<br>
unicast:<br>
11 packets received, 0% packet loss<br>
rtt min/avg/max/std-dev = 0.107/0.261/1.592/0.421 ms<br>
multicast:<br>
0 packets received, 100% packet loss<br>
<br>
<br>
<br>
and here are two other servers (ubuntu and debian) connected to
the same set of switches as the servers above:<br>
<br>
root@test2:~# asmping 224.0.2.1 testserver1.npr.org<br>
asmping joined (S,G) = (*,224.0.2.234)<br>
pinging 172.31.2.125 from 172.31.2.131<br>
multicast from 172.31.2.125, seq=1 dist=0 time=0.203 ms<br>
unicast from 172.31.2.125, seq=1 dist=0 time=0.322 ms<br>
unicast from 172.31.2.125, seq=2 dist=0 time=0.143 ms<br>
multicast from 172.31.2.125, seq=2 dist=0 time=0.150 ms<br>

unicast from 172.31.2.125, seq=4 dist=0 time=0.122 ms<br>
.........<br>
<br>
--- 172.31.2.125 statistics ---<br>
9 packets transmitted, time 8115 ms<br>
unicast:<br>
9 packets received, 0% packet loss<br>
rtt min/avg/max/std-dev = 0.114/0.150/0.322/0.061 ms<br>
multicast:<br>
9 packets received, 0% packet loss since first mc packet (seq
1) recvd<br>
rtt min/avg/max/std-dev = 0.118/0.142/0.203/0.026 ms<br>
<br>
As you can see multicast works fine there.<br>
<br>
<br>
All servers are running 2.6.32 kernels but not all the same
version (2.6.32-23-pve - 2.6.32-37-pve)<br>
<br>
Anyone have any suggestions as to why the Proxmox servers are not
seeing the multicast traffic?<br>
<br>
Thanks,<br>

Is the "pvecm nodes" similar in all nodes?<br>
<br>
I don't have experience troubleshooting corosync but it seems
you have to re-estrablish the corosync cluster and quorum.<br>
<br>
Check "corosync-quorumtool -l -i" . Also check cman_tool
command for diagnosing the cluster.<br>
<br>
Is corosync service loaded and running? Does restarting it
change something (service cman restart) ?<br>
<br>
