Hi all,
I'm trying to migrate my corosync.conf file's settings into
cluster.conf. I discussed this with people on IRC, but I wanted to start
a thread as I think this is a bigger issue that would benefit from a
consistent thread.
As I understand, any arguments in cluster.conf should be fed to the
corosync preconfig. From there, defaults should be applied and the whole
shebang should go into corosync-objdb. However. when I put a ticket[1]
in for a related problem, Lon mentioned that some arguments are not yet
supported and thus do not have support in cluster.rng. These two
statements seem to contradict each other. Can this be clarified?
Next, I stripped out the questionable arguments and tried to load
cman with the cluster.conf having the totem arguments. Specifically:
<totem rpp_mode="passive">
<interface ringnumber="0" bindnetaddr="10.0.1.0"
mcastaddr="226.94.1.1" mcastport="5405"/>
</totem>
With the above argument in my cluster.conf, it passed validation but
then failed to start with:
Starting cluster:
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... [ OK ]
Mounting configfs... [ OK ]
Starting cman... corosync died: Error, reason code is 8
[FAILED]
In the log file, I saw this error:

I don't think this is a syntax problem. When I remove the <totem />
section and start cman, it comes up fine. Further, there is a totem
ring, which I assume the adapter created out of defaults. I can see this
via corosync-objctl (sorry, I don't have the exact output at the
moment). There are several 'totem.X' entries, of which, one is 'mcastport'.
Finally, when I shutdown cman, setup my corosync.conf file and start
it by itself, the configuration loads. In fact, there I can specify a
redundant ring and corosync-objctl shows both rings.
Any idea what's going on here? Should I submit a new bug?
Thanks in advance!
