Server :: Beowulf Cluster With Xen On IBM Bladecenter For Private Virtual Machine Farm
Feb 16, 2009I'm probably dreaming, but I have a hobby project in mind that I would like feed I have an opportunity to purchase a 3 year old fully populated (14 x 3Ghz dual Xeon nodes) IBM bladecenter relatively inexpensively.I thought it would be fun to set it up as a beowulf cluster with open source xen and test the market to see what people would pay for Private virtual machines.
My thoughts are to use 64 bit Centos 5 as a base to get the beowulf cluster up and then load xen.I haven't really looked at the market but I figure I should be able to run 50 private virtual machines charging say $50 per month. I figure I can use rsync to backup the virtual machines to a different location. I plan to connect to linux based Network Storage running 3 x sata 1TB drives, probably via iSCSI. Along with the drive capacity currently on the blades I should get 2-3Tb online capacity over a Gbit network. (Cisco 14 + 4 network switch module)
I realise I have a bit of setup work to do and before I go investing a lot of time and a little money I'd appreciate some pragmatic advice as to why this may be a stupid venture.
Ubuntu Servers :: Setup An Apache Web Cluster Using Red Hat Cluster Suite
Sep 1, 2011I 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.

Nov 6, 2010I 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.

General :: Difference Between Cloud And Cluster?
Oct 3, 2010I 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, 2011A 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.
View 1 Replies View RelatedGeneral :: Best Way To Handle Cluster Failover
Sep 30, 2010We 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.

General :: Error While Building A 3-node Cluster ?
Jan 6, 2010I'm building a 3-node cluster. I have created ocfs filesystems and mounted them on the first two nodes. But while mounting them on the third node , i'm getting this error for 8 of the total luns. all these 8 luns are of 1GB size.
I've unmounted these 8 luns from the other node and tried to mount in the third node ... and then it was working and again the error occurs in the second node. My observation was for some reason these particular luns are not allowing the third node.

Ubuntu :: GParted - Cluster Accounting Failed
Feb 12, 2010I've looked all over the web, but don't see an answer to my particular case. I'm in GParted in Ubuntu Live CD 9.10 amdx64 To prep for Ubuntu install, I'm attempting to resize and re-partition my second hard drive which was FORMERLY my primary boot drive for Vista before it crashed a few days back. It is CURRENTLY my Vista User data file and is about 250Gb in size. The drive is a SATA 500Gb total.
But GParted now all of a sudden gives me several "Cluster accounting failed at blah blah: missing cluster in $Bitmap" error messages. Is there a good way to 'fix' these errors? (besides reformatting it) I deleted the long-winded background, so let me know if you need more info. Short version: I installed vista by reformatting my 120Gb data drive as the primary master now. Then I plugged in my 'previous' 500Gb Sata drive, and pointed Window's User folder to my old User folder, and voila, was back up and running in Vista... minus all my programs. but now, both drives are recognized by GParted as "boot" drives.

Ubuntu Servers :: Setup A Cluster Using Heartbeat?
Jun 29, 2010I am currently trying to setup a cluster using heartbeat. Unfortunatly it does not do what I want to do. I am using heartbeat 2.1.4-11 on a readhat system. I am using the the cib for configuration. What I want to do is the following: I have two Nodes. I want to run a clone resource on both nodes. It's named I want to run as a clone. This works fine.Additionally I want to have two virtual IP adresses. One should be set on Node 1 the other on Node 2. This works fine as well. I want to set dependencies between the resources. And this is where I have problems. What I want to achive: In case named is not able to run on a node, the vIP should switch to the other node (which then will have both vIPs). In case both nodes are able to run named, there should be one vIP on each node. Sounds simple, but does not work.Accourding to the heartbeat docu this an be achieved by using
