I need to build a cluster with vmware with 2 linux nodes but I'm a bit of a begginer. I have this questions:
Wich vmware to use (server, workstations)? Do I need a server OS? Wich linux OS to use? how to create the cluster? How do I test it? How do I run a program in paralel?
Since new kernel 3.0 update I cannot rebuild vmware modules
Quote:
sudo vmware-modconfig --console --install-all Unable to initialize kernel module configuration
how to do that. Where do I insert the "CONFIG_LOCALVERSION" line.
Quote:
Same here. This seems to be due to the kernel version being "3.0" instead of "3.0.0". Recompiling the Kernel (and all modules based on it, e.g. nvidia) with
CONFIG_LOCALVERSION=".0-ARCH" allows me to compile the modules and run VMware.
I am planning to configure RedHat cluster on vmware, i dont know how to configure, i googled a lot but couldn't find satisfactory docs for configuring, can any one provide me step-by-step or good docs to go ahead.
View 1 Replies View RelatedI am using Centos. I have read places that you can use Drbd + heartbeat + nfs to make a simple failover NFS server.I can't find any document that works though. I've tried 20 or so, including some Debian ones.So, does anyone have any other ideas of how to do this?Point me in the right direction please.I want 2 nodes. One to be actively serving an NFS share The other to be ready for failover. If the first one goes out, the second takes over.Meaning, the filesystem is in sync, the IP must change, and NFS must come up

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.

I have a problem with the VMware Workstation 6.5.2 build-156735 on CentOS 5.3. When I start a VM then, after 10-20 minutes the machine and VMware Workstation freeze. The mysterious thing was, after the freeze a large of folders from my two partitons were lost. ( I have two partitons on a NVIDIA Raid,configured with dmraid.) But the partitons still here, I can see them and they are mounted. Its very mysterious.
I have installed the VM's to a folder on my raid. When I killed the processes and restart VMware Workstation I cant start a VM.
VMware says that CentOS 5.3 are supported for the VMware Workstation 6.5.2 build-156735.
I'm trying to build a Fedora 12 cluster to run DHCP on top of two servers using pacemaker and drbd. The pacemaker runs great but i'm having the hardest time getting DRBD installed.
My kernel version is 2.6.32.11-99.fc12.i686.PAE First i tried to [root@dhcp-primary drbd]#yum install drbd this doesn't give me everything because apparently the kernel module for DRBD must be built from source. so i unpacked drbd-8.3.6.tar.gz and tried :

I'm not very experienced in compiling from source i'd love to make an rpm for this but after scouring the web and trying different install methods, I am still at a loss.
I have a fresh installation of Fedora14_x64 and after that I have updated the OS also.
Then I have installed VMware-Player-3.1.2-301548.x86_64.
All the installation procedure has completed successfully without any error.
But when I am going to run VMWare It is throwing some error.
I am attaching all the needed screenshot and log file also.
I've always been interested in Linux and it seems that the new version of Ubuntu (10.04) is pretty good. Now I want to build an Ubuntu desktop to use as my main computer. I've been running it through VMWare Fusion and I haven't had too many problems at all on my iMac (27" i5). Unfortunately, I still need my iMac since the new Steam client is coming out for OS X and I must have some of my Steam games. I guess I don't mind running it in VMWare, but I do miss the excitement of building a new computer with a nice case and fans, and throwing a fresh clean OS on it. Anyone else been in the same dilemna? I feel though I have spent enough money on computers recently. Plus, I don't have room on my desk for another widescreen monitor. I'm not sure where I would put my iMac.
View 3 Replies View RelatedI 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.

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 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.
View 5 Replies View RelatedI have been using VMware Player for some time to host Fedora VMware images on Windows XP. I have been using Fedora 11 and 12 (both 32 and 64 bit) and recently started to use Fedora 13.
I use as a base the images provided by thoughtpolice. http://www.thoughtpolice.co.uk/
I usually install VMware tools and also keep the images updated (yum update) which sometimes changes the kernel.
I have recently had problems with the snapshots not having a network when I restore them. So far I don't have the problem with Fedora 11 and do have it with Fedora 12 (but used not to). I do have it with Fedora 13.
In each case the problem goes away when I uninstall the VMware tools and comes back when I install them again.
One of the symptoms is that SElinux complains about not being able to do something with /var/run/vmware-active-nics.
It looks to me that something is incorrect in the actions being taken when the snapshot is being restored. It does not happen every time and sometimes the network restores itself.
The network can be restored by rebooting the image.

View 1 Replies View RelatedI am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.

/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...
I have installed fc12 on my core2due machine, and I have installed the vmware server on it, its rpm is installed successfully with out any error, after that a message is displayed
The installation of VMware Server 2.0.2 for Linux completed successfully. You can decide to remove this software from your system at any time by invoking the following command: "rpm -e VMware-server".
Before running VMware Server for the first time, you need to configure it for your running kernel by invoking the following command: "/usr/bin/vmware-config.pl".
I tried this command and find the this message
[Akram@localhost Downloads]$ su -c "/usr/bin/vmware-config.pl" Password: Making sure services for VMware Server are stopped.
None of the pre-built vmmon modules for VMware Server is suitable for your running kernel. Do you want this program to try to build the vmmon module for your system (you need to have a C compiler installed on your system)? [yes] yes
Using compiler "/usr/bin/gcc". Use environment variable CC to override.
Your kernel was built with "gcc" version "4.4.2", while you are trying to use "/usr/bin/gcc" version "4.4.3". This configuration is not recommended and VMware Server may crash if you'll continue. Please try to use exactly same compiler as one used for building your kernel. Do you want to go with compiler
"/usr/bin/gcc" version "4.4.3" anyway? [no] yes
What is the location of the directory of C header files that match your running kernel?[/usr/src/linux/include]
Now it asks me in last lines that "What is the location of Directory of C header files that match your running kernal?"
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.
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.

View 14 Replies View RelatedWe 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.
I was following [URL] for the cluster setup. But things dint work out. One Doubt to ask "Do I need the services cman, ccsd and rgmanager one at a time on the both machine. I have been running it through script.
