Hi Gordon,

It looks to me like things have changed quite a bit in F13 compared to RHEL
/ Centos 5. I agree, cluster.conf  looks the same but there is a new
component called Corosync and ccs seems to have gone.

Take a look here:

http://people.redhat.com/ccaulfie/docs/Whither%20cman.pdf

From RHEL5 to RHEL6 you change from cluster 2.X to cluster 3.X

Documentation can be found here:

http://sources.redhat.com/cluster/wiki/

Traditionally I have used Conga to configure the Cluster (although not
without problems at times it has to be said). However, in F13 there is no
"luci_admin" utility to set the password and Luci isn't accessible from a
web browser. I don't mind configuring things by hand if that's the only way
to do it, I was just looking to be pointed in the right direction really. I
have received some help offline from a member of this list which has proved
invaluable. I have now managed to get a basic cluster up and running on F13.
Our fellow list member is working on a document which I think will be of
enormous help to others when completed (in fact it is already a useful doc).

Docs on Conga (Luci and Ricci) are here:

http://sources.redhat.com/cluster/conga/

If you want to use a GUI to configure clustering you will most likely have to wait at least until Fedora 14. Luci is not functional in the current fedora (and hasn't worked in the last several releases).


I don't know if this is newer because i made a large way around even
trying to use conga after i spotted that it utilizes turbogears (which
has a huge dependency tree just to get anything out of it).

The old docs specified which ports / protocols needed to be opened up in
iptables but as I haven't sussed out what's needed under F13 I am running
with iptables stopped for now. If anybody has this information I would be
very grateful to receive it.

The FAQs on http://corosync.org/ and http://openais.org/ could help
here. Unfortunately the FAQ entry about firewalls has no content.

Bug?!

A "netstat -tulpen" on a root shell should show the ports that corosync
and openais listening on. They use a single multicast port if i'm not
mistaken.

Thanks&  regards

John
