Hi, I am a complete newbie and I've just subscripted a Red Hat Enterprise Linux 6 beta version to try out its Cluster Suite. I am looking to build a 2 node cluster running a High Availability service, But as I try to do this (starting) I get the following problems.

1) I don't seem to be getting the cluster.conf file that the everybody talks about. I have definitely installed the High Availability and Clustering options during installation, but all I get in the /etc/cluster directory is empty folder namely cman-notify.d


2)I am getting is that I've started a luci service and I am able to access it from web browser by https://host:8084 but when I create a cluster it doesn't show itself under "Manage Cluster" menu, I have to type to URL in to access it, even so it says none of the nodes can be connected... (p.s. don't know if it is version related but the UI i ma getting in luci is different from the one I see on administrative guide (The one with 3 tabs))

3)Since the experience with conga seem to be failed, I might well try the system-config-cluster, according to the documentation I can use the command "system-config-cluster" to get a GUI for managing my cluster, but when I type that into the terminal all I can is

-bash: system-config-cluster: command not found

And that happens for lots of other commands that appears on the doc, such as # luci_admin init

4) What other service to I need to enable and start? By default most of the services are disabled, I have switched on clvmd, cman, luci, ricci, modcluster and rgmanager at the moment, and corosync and cmirrord failed to start for some reason. Are all these necessary??

Hi Learning Curve,

RedHat provide documention on cluster. Have a look, it helps you to learn and setup cluster.

RedHat Cluster

hello frnds....

i am implementing cluster with two linux systems having centos 4.8
and i implemented the cluster manager on one system(node 1) and all the services
are running well on that system....

#service ccsd start
#service cman start
#service clvmd start
#service rgmanager start.....

after that i want to add the other system (or node 2) to the first
system (node1) as a member of cluster....
for this,i am adding the node in cluster configuraion tool on left
side option of cluster nodes and do all the configuraion for that
node(node 2).

After this i stopped all the services of node1 and copy the cluster
configuration file(/etc/cluster/cluster.conf) using scp command to other node(node 2)
and restart all the services on both nodes node1 and node2.

All services started on node1 but no services started on node2 (except ccsd) in which i copied the
cluster conf. file and gives an errror.....

#service ccsd start.......[OK]
#service cman start.......[FAILED]
#service clvmd start......[FAILED]
#service rgmanager start.....[FAILED]

and also shows the error could not connect to the cluster manager

when I saw the status of cluster using....
#clustat

it shows....

Mamber status: Quorate
Member Name status
node1 Online,Local,rgmanager
node2 Offline

So any one tell me where i'm doing mistake in adding the node or
is there any other problem in implementing the cluster.

please reply as soon as possible......

how can i start cman service....
I have already install the all rpms of cman,rgmanager,magma,dlm etc for implement cluster by yum.
and I think i will not be able to implement cluster until the cman servies start....


any one can tell me the solution for this....reply soon

Hi Friends..........


I would like to tell you guys about what i wanna to do....


I want to make a kickstart DVD/CD for two servers having same Hardware configuration,
it means that if I installed any software,or create any RAID,heartbeat etc. on any
one server say server1 and i don't want to do these steps again on second server
say server2.


I just want to make a Kickstart DVD/CD of server1 which have all the configuration
what I have done on server1 (RAID,Heartbeat etc.).

when I insert the DVD/CD on second server say server2 than the software of server1
means RAID,Heartbeat etc...what i have configured on server1 automatically installed
on server2(RAID Configuration,Heartbeat)....

After the boot of second server from kickstart DVD/CD,there is no need to configure
RAID,Heartbeat etc. again on second server (server2),it installed automatically those software(RAID,Heartbeat) from Kickstart
DVD/CD.....

as a result both the server will have same configuration of RAID,Heartbeat etc. what I have
configured......

I think you all guys are understand what i want to do....

So I want your help for this.

If anyone know the answer or any logic please reply me as soon as possible...

I'm waiting for your reply
