Red Hat Cluster Suite on CentOS

ivandrago · 01-04-2012, 04:26 PM

I am running CentOS 6.2 and it is fully updated. I installed the HA package and everything works fine until I install libvirt. After I install it, Luci times out when trying to contact Ricci. As soon as I remove it, it works fine. All the logs provide is : The read operation timed out. Iptables is turned off and selinux is disabled. I can ping, SSH etc... with no issues. HELP!

well we would need more information than this

How did you install it ?
And what version ?

NOT a good idea unless this cluster(of unknown size ? how many boxes are connected ?) has NO INTERNET CONNECTION - none what so ever .
if it dose , then leave them ON and configure them to work with your set up.

I installed it using yum install libvirt. I am unsure of the version.

Code:

# yum info libvirt

will give you version info and source of rpm etc.

are these server names (like Dolce is trying to contact Gabbana)?

Ricci is the cluster client software on each server. Luci is the cluster management software. Both are part of the RHCS. Selinux and iptables are just disabled for troubleshooting purposes. The versions are below.

Name : libvirt
Arch : x86_64
Version : 0.9.4
Release : 23.el6_2.1

This fixed my issue.

Problem: Conga fails to create a cluster or when trying to add a node with the following error:

Error receiving header from <nodename>:11111

create the directory below.

# mkdir /var/lib/ricci/.libvirt

# chown ricci:ricci /var/lib/ricci/.libvirt
