Fedora Servers :: How To Setup GFS2 Without Cluster Suite / How To Configure Cluster.conf

Nov 6, 2010

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.

Ubuntu Servers :: Setup An Apache Web Cluster Using Red Hat Cluster Suite

Sep 1, 2011

I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

CentOS 5 Server :: Cluster Suite CLVMD ?

Jul 17, 2011

I have just installed a two server cluster with ricci luci and conga on centos 5.6 32bit , both servers are vmware guests and have a shared storage disk connected to them both

with a GFS2 file system on them + fencing agents configured to work with VMware Vcenter.

(this is supported by vmware and works great on 4 other centos clusters i have been runing for 4 monthes with no CLVMD).

In this setup i used for the first time CLVMD as recommnded by RedHat so i could have the flexablitly of LVM under the GFS2 file system but , i have been getting some Strange problem with it , some times after a developer has done some IO heavy task like unziping a file or a simple TAR the load goes to 10 - 15 and no task can be killed , trying to reboot the server hangs.

After hard shutting the server every thing works ok until the next time some one does the same IO work as before.

CentOS 5 :: Cluster Suite And Fence For VMWare ESXi 4.0

Oct 22, 2009

This is my first post, and i have a question with the fence software for VMWare ESXi. The fence_vmware agent only works with ESX, and redhat (in you GIT repository) has submited a new agent called fence_vmware_ng that claims to work with ESXi. But the problem is that they do not specify the version that works with that. Anybody has test the fence_vmware_ng agent for VMWare ESXi 4.0 ?, i follow the instructions here: [URL]...and i can install the software, the API from VMWARE site, etc, but in the moment when i run the agent nothing happen, The agent connects to server, i see in logs, but the off-reboot-on operations not works. Only works status operations, that return the state of a virtual machine. I have CentOS 5.3 (fully today updated) with RHCS.

General :: Ways Of Setting Up The Cluster.conf File?

Jan 26, 2010

I've tried many, many different ways of setting up the cluster.conf file, but every time I start the cman service I get a message telling me "corosync died: could not read cluster configuration".This means nothing to me, nor can I find logs, or anything on the net about this message. I'm ultimately just trying to run a simple GFS2 config on 2 Ubuntu 9.10 desktop nodes, but I can't even get a basic cluster config going.What am I missing? I've been at this for days.

Fedora Servers :: Setting Up A Cluster For Scientific Computing?

Mar 2, 2010

I want to set up a cluster for scientific computing (mainly statistical stuff with R). I have a few conceptual questions. First, is there a difference between a Beowulf cluster and a cluster that has single-system image ("SSI," e.g. using openSSI or LinuxPMI)? If so, what's the difference? Second, if there is a difference between Beowulf and SSI, which one is better for scientific computing? Third, does using Eucalyptus make sense for scientific computing or is this more suitable for IO-oriented operations such as web service or databases

Server :: Setting Up A Cluster Specifically For 3D Video Rendering?

Nov 1, 2010

I'm planning on setting up a server cluster specifically for 3D video rendering. In order to maximize speed I wanna use OpenGL hardware acceleration for that and I'm pretty sure that I have to use an NVIDIA video card if I want the whole thing working reliably. Will I be able to start an X-Server with GLX on an NVIDIA video card that doesn't have a monitor connected to it? And what will be the maximum "virtual" display resolution that I can use?

Since I wanna have several servers running side-by-side I really don't have the room for any monitors.Just to avoid misunderstandings: It is not my intention to show what's being rendered to anyone in real time. I will only create video files that can be downloaded later. I'm already pretty sure that this will work, probably using "CustomEDID" or something like that, but I don't have a suitable setup available to test it right now.

Server :: Install Red Hat New Cluster - Error: Cman Not Started: Cannot Start, Cluster Name Is Too Long

Mar 15, 2011

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.

General :: Substitute For Nokia PC Suite Or Synchronizing Data From A Nokia Phone

I was looking for a way to get the same or similar functionality as the Nokia PC Suite on Ubuntu 10.04. I did find a discussion here [url].

However it is fairly old (2008). I was wondering if it is possible to get more recent information.

In the Ubuntu Software Center I find two applications that seem to fit the bill. I need to know which is better or are the complimentary.

General :: Difference Between Cloud And Cluster?

Oct 3, 2010

I have read several articles online trying to get a grasp and understand on a simple question. What is main difference and functions of cloud server infrastructure and cluster server infrastructure

To my understanding, the the basic setup is sort of identical in a way. They both have a master server (3 GHz, 2GB RAM 50GB HDD), from there it connectes to a switch, then a number of nodes (each 2 GHZ, 4 GB RAM, 100GB HDD) connect to the switch.

The cluster combines node resources so it looks like one computer (5 nodes = 2GHZ x 5, 4GB x 5, 100GB x 5 = 10GHZ, 20GB RAM, 500GB HDD). If this is correct, this sounds good for possibly Database or File server. The resources on cluster would be constant. Example would be Database Server. While running DB server it starts to slow down because of all the data it is trying to store and retreive. If you ned more resources, just add another node.

The cloud uses only resources it needs to run (same numbers as cluster). This is good for Database or Web Server. Example: Web server is hosting 10 domains each with 20 pages. One hour it uses 3 GHZ and 8 GB RAM, next hour it is getting heavy traffic so it uses 9 GHZ, 15GB RAM.

But from what I have gathered and read, this is how I am interpreting the information and understaing it. Plain and simple.

General :: How To Make A Cluster Desktop

Jun 22, 2011

A Supercomputing cluster running a linux OS would have, say, 100 nodes. The hub (I think that's the term) would be running Gnome, KDE, or some other desktop gui. Any vital programs would also be running from the hub. Any other processes, however, would be delegated to a hub, much like individual cores in a multi-core tower. That way, you could be running 500+ intensive programs, relative to the nodes' power, and they would all run perfectly smoothly.

General :: Best Way To Handle Cluster Failover

Sep 30, 2010

We have setup a High Available Cluster on two RHEL 5.4 machines with Redhat Cluster Suite (RHCS) having following configuration.

1. Both machines have Mysql server, Apache web server and Zabbix server.
2. Mysql database and web pages reside in SAN.
3. Active machine holds virtual IP and mounted shared disk.
4. We have also included a script in RHCS which takes care of starting Mysql, Apache and zabbix server on the machine which turns active when cluster switches over.

The above configuration holds good if Active machine goes down as a result of hardware failure or Reboot. What if, If any one service say Apache/Mysql/zabbix running on active hangs or become unresponsive.How can we handle this scenario ? Please advice.
