I came across this while trying to find a solution for my load-balancing clustering issue in another thread. Since I perceive this as something on its own, I decided to post a new thread. I came across this site to setup a two-server cluster using Conga - Luci and Ricci.
From my understanding, this is what was done:-
1. Both servers have luci running using a shared storage via GFS to provide a failover
2. Both (and same) servers have ricci agent running for the clustering
I'm aware that Conga clustering aim to achieve High-Availability.
1. Can it also achieve Load-Balancing?
2. If yes, would the guide from the link above be sufficient or would they be additional setup/pre-req to be done? Since I'm new to this area and there was no mention of load-balancing, I'm still wondering if this is what I need to incorporate.

I'm trying to build cluster computer system using redhat linux enterprise 5.5. And I'm on the step to set up the NFS mounting. (step 3 of part VI on this paper: However, I kept getting "permission denied" when I used the command "mount -t" to mount the slave node onto the hard drive of the master node. Even when I edited /etc/fstab file to make it automatically set up during booting, I still receive the same result. By the way, I've already logged in as a root user on both slave and master nodes.

I have added apache application into redhat cluster. If the apache process failed, it will cause the service group fail over. I want to disable the application monitoring. I search throung Internet and it depends on the apache init script. If I change /etc/init.d/httpd status always return 0(success). THe service group will not fail over even apache failed.
However, I want to remain the application monitoring but stop failover. If the application like apache failed, I want Redhat cluster to try restart the application like 3 or 4 times. If restart failed, it will not failover.

Im having a frustrating issue with my two machine cluster I setup using Conga. Everything was working great except now when lucci starts mysql the port (3306) is never opened to outside machines. I can do a "ps -ef | grep mysql" and see it running as well as login to mysql on the node it is running on - but an nmap of the machine does not show the 3306 port and I cannot login to mysql remotely and yes I turned off all iptables(iptables,ip6tables) and SElinux is disabled.What am I missing here? If I start mysql on my own (and it is using the same my.cnf as lucci is) it does show the port open and works perfect,t for some reason when lucci starts it, no dice

I have installed on a remote server phpmyadmin 3.3.1 and mysql 5.1.46 on a centos 5.4 OS.
Any newly created user with phamyadmin is unable to login both from mysql command line (from localhost) and phpmyadmin (localhost and remotely).
No prob when the user is created with mysql command line (from localhost). All of the users created with phpmyadmin, are not "visible" recognized from the show user command via the mysql command line. The setting I used when I create any user was the same as the ones with the mysql command line creation.
The error message I get when accessing from mysql command line (from localhost) is the following: "Access denied for user ... @localhost (using password: yes)"

I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :

And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

I was given task to install redhat linux os on one of the compute node on server which doesn't have cd/dvd drive or usb port.I have installation media as well ISO image. This server is on network, so I can access it via my PC which is running window 7.I think, I have 2 choice to install:1. Copy iso image to head node on server and then install linux os on compute node via nfs.r2. Use my PC dvd drive to install linux on compute node via network.But I don't know how to do it.

I have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
