redhat linux cluster

[Marcelle Farag_1]

hello,
i have couple of x86-64 instances of vmware running rh5. i'm tasked to document a POC on how to install, configure redhat linux cluster. questions i have:
1) is it possible to run cluster over virtual redhat instances?
2) is there any documentation that outline the prerequisites, such as shared SAN space, multicast IP, etc...
3) the image i was given seem to be missing main rpm dependencies of ricci/luci packages. is there a documented way to install a main rpm and dependencies in one step? i seem to be getting into a vicious loop of installing rpms as each failed due to dependencies...

thanks, marcelle

Shalom marcelle,

1) Yes. You still need a fence device and certain vmware schemes provide this. A fence needs to be able to shutdown a culster node.

2) There is no shared disk requirement.
http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/ch-software.html

3) May I suggest yum.

Lets say you need to install ricci

yum install ricci

yum calculates the dependencies and creates a good install set, downloads it and installs it.

Of course for yum to work, you need to have your system registered.

Hi Marcelle,

Check the following links on how to go about configuring a red hat linux cluster.

Configuring and Managing a Red Hat Cluster
http://www.centos.org/docs/5/pdf/Cluster_Administration.pdf

Red Hat Cluster Suite: Configuring and Managing a Cluster
http://www.linuxtopia.org/online_books/linux_system_administration/redhat_cluster_configuration_and_management/s1-hardware-cluster.html

Hope this helps.

Regards,
Murali

thank you.

so i started to use yum to install ricci package. as discovered previously, it had 2 dependencies - modcluster and oddjob. since modcluster also has dependencies on oddjob, i then downloaded oddjob rpm. the delema here is that oddjob get me into what seem to be an endless loop between oddjob-0.27-9xxx and oddjob-libs-0.27-9. also i can not find liboddjob.so.0()(64bit). any idea what i'm missing?!

this might help you out

If you don't have connectivity to RedHat Network, you will also need this to use the full potential of yum:

hello and thanks for the links and all feedback.

since this environment is not registered with RHN, i'm following the link to run yum and install the cluster suite package. i have a question about the package name as identified in the second step...

yum install --noplugins

how do i know the package name for the redhat cluster suite? i tried Cluster and ClusterStorage and neither worked.

thanks for helping.

[Gerardo Arceri]

I think that you are looking for

http://kbase.redhat.com/faq/docs/DOC-5977

The entire set of Default Packages from either the Cluster or Cluster Storage group can be installed manually using the yum command:

# yum groupinstall Clustering
# yum groupinstall "Cluster Storage"

Alternatively, a subset of those packages can be installed if the entire group is not needed. For example:

# yum install cman lvm2-cluster kmod-gfs gfs-utils

Hope it was helpful!

hello, the nodes are not registered to RHN. therefore i must install the cluster suite manually.

with that in mind, i created the local repo file to point to the mounted DVD, then ran yum command to install ricci as an example, with no success. the rpm is indeed in the /mnt/Cluster directory...

#yum install ricci-0.12.1-7.el5.x86_64.rpm

i also tried the groupinstall, it displayed all sort of errors - dependencies related error.
