So I'm trying to setup a cluster with a secondary communication ring
in case the first ring fails. The cluster operates fine, but doesnt
seem to handle path failure properly. When I break the path between
the 2 nodes on ring 1, I get the following in the logs:<br>
<br>
Jan 6 16:55:17 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
Incrementing problem counter for seqid 202 iface 165.212.15.49 to [1
of 3]<br>
Jan 6 16:55:19 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
ring 1 active with no faults<br>
Jan 6 16:55:24 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
Incrementing problem counter for seqid 204 iface 165.212.15.49 to [1
of 3]<br>
Jan 6 16:55:26 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
ring 1 active with no faults<br>
Jan 6 16:55:30 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
Incrementing problem counter for seqid 206 iface 165.212.15.49 to [1
of 3]<br>
Jan 6 16:55:32 syslog02.cms.usa.net corosync[13931]: [TOTEM ]
ring 1 active with no faults<br>
<br>
And it just repeats over and over. From notes I've found from
others, it appears this might be because of each ring sharing the
same broadcast address. Indeed this is the case as `cman_tool
status` shows<br>
Multicast addresses: 255.255.255.255 255.255.255.255 <br>
Node addresses: 165.212.64.49 165.212.15.49 <br>
<br>
However I've tried changing this address in the cluster.conf and it
seems to be completely ignored. I've also tried changing the port
for the second ring and thats also ignored (tcpdump shows them still
going to the same port as ring 0).<br>
<br>
So, is this indeed the cause of it not properly detecting ring
failure? And if so, how can I fix it?<br>
