Just a note, luci in F11,12,13,etc. Is completely non-functional. It is missing large sections of code to even make it work. There is the possibility that a working luci will be present in F14, but right now the only way to configure the cluster is by editing the cluster.conf file.


I found the same myself when trying to configure, using the luci_admin
from RHEL 5 did not work either, I even went as far as e-mailing the
dev from Redhat who compiled the FC13 version to try and get the
default password but have had no reply (e-mail sent from work account
and I do not have access to it at the moment)

as for the Luci not being available, I believe that it is now running
on a different port, from what I can remember it is now on 8080 ( a
netstat -an| grep luci should get the port)

When you load this up you get a demo version of Luci with systems
populated, and it looks nice!

I also tried the RHEL version of Luci against the FC13 cluster with
mixed results (if you count it not working as a mixed result!)

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.

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).

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.

Thanks&  regards

John

Maybe I'm missing what exactly you guys are talking about, but
everything I can think of in RHCS is configured via cluster.conf. My
cluster.conf files from RHEL5 work just fine on RHEL6 beta, which is
virtually identical to F12/F13. I don't see why you would have any
problems getting RHCS to work on F13 using the same instructions you
would follow for RHEL/CentOS 5.

Hi John..

Normally I do not agree with replying to posts without anything
constructive to say but I thought that I should in this case.

I have to admit that I ran into the same issues as you, I built a RHEL
5.5 cluster and decided to give the FC13 path a try, Tried to use Luci
/ Ricci to configure the nodes and had no luck even managing to log
into Luci, no documents / man pages included with the packages and the
readme file that was included was the same one that was included with
the old source files, and had not been updated since.

In the end I gave up and went back to RHEL.

(that said you can go the heartbeat route, this I got to work when
using oracles ocfs as a shared data store on drbd)

From

changed quite significantly. It looks like openais / corosync are new
