Hello,
    after upgrading to 3.0.6 i get:

Starting cman... Relax-NG validity error : Extra element cman in interleave

but cluster.conf should be correct and was working so far without problems.
The coresponding section in<cluster>    is:

<cman expected_votes="7">
      <multicast addr="239.192.11.81" keyfile="/etc/cluster/cman_authkey"/>
</cman>

how should i change it to pass the validity check?

Remove the keyfile="" attribute. cman ignores it anyway :-)


I am sure it was working with RHCM v2, so it seems i will need to rewrite the
config for V3, as i get another error now about specifying multicast interface
for clusternode and there will be others for sure

Yes, it would work fine under v2. In fact it's working now - you're just
getting a warning message (I hope!). We have added a lot more checks to
the configuration to try and help invalid configurations from being run
and causing trouble.

when starting the cluster i get just warnings, but updating the config and
using cman_tool version -r cman doesn't reload it, so i am forced to fix my
errors :)


If you need to specify an encrpytion key it should go into the<totem>
part of cluster.conf.


looking at cluster.rng keyfile is valid for the cman block. May i just move it
there or i should create<totem>

I would just remove it. It's not doing anything, so if you move it to
<totem>  you will change the encryption key used by the cluster and have
to reboot all your nodes to get them communicating again.


The cluster is not a production one, so it is OK and am looking for the
correct end result. My question was actually 'Is encription key valid/used
only from<totem>  section or in<cman>  too as described in cluster.rng file'.

Multicast and keyfile are present in both<cman>  and<totem>  ... i guess
<totem>  is the preferred one for future compatibility?


Confusingly, multicast must be part of <cman> and keyfile should be part of <totem>.

That's just how it is, sorry ;-)
