Fedora Servers :: Build A F12 Cluster To Run DHCP On Top Of Two Servers Using Pacemaker And Drbd?
Apr 28, 2010
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 :
[Code]...
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 need to build a 3 node web server cluster to run a php application. Since the app requires users to login (which means a session state is to be maintained), I will be sharing sessions save path, I also need to share the application directory across 3 nodes. I having trouble deciding which cluster file system to select.
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.
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.
It seems to be drbd is not available in ubuntu 10.10 at all. I just installed the drbd8-utils package thinking the kernel module would already be built-in. But I guess not, because here is the error I get:
Code: # drbdadm syncer r0 Could not stat("/proc/drbd"): No such file or directory do you need to load the module? try: modprobe drbd Command 'drbdsetup 1 syncer --set-defaults --create-device' terminated with exit code 20 drbdadm syncer r0: exited with code 20
i have a two node drbd cluster, while drbd1 is primary and drbd2 is slave i should make drbd1 slave and unmount drbd partition and make make drbd2 primary and mount drbd partition to see content on drbd2is it any way to automate it so as drbd1 goes down, drbd1 make itself primary and mount the partition?
I'm trying to configure an ISCSI/DRBD high-availability cluster and I'd like to know what is the best option between OpenAIS and Heartbeat. I've seen they both are included in Centos Repos, yet OpenAIS requires installing 2 addition repos to install Pacemaker (EPEL and Clusterlab repos).
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
Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received: Login to your windows server and load the DHCP configuration screen Create a DHCP reservation for the MAC address you obtained Add the configuration options below to enable the machine to boot from the LTSP server 017 Root Path: /opt/ltsp/i386 066 Boot Server Host Name: <ip address> 067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I am trying to install a Red Hat cluster on my servers. In order to configure an heart bit between the servers I must give a valid multicast address. I wanted to know if there is a way to validate a multicast address before using it. For example if it is already in use i don't want to use it.
I read a little about it and there is a Perl module called IO::Socket::Multicast: [URL] There is a tool called mcasttrest.pl: [URL] Oracle use it to test multicast. But I am not sure what will do the trick in Red Hat cluster.
have f13 runing and finished configuring dhcp. but i tried to start the service using '/etc/init.d/dhcpd restart and service dhcpd start', i failed in return. pls what could be responsible? tried starting the service but still failed. could anything be stopping it?output from /var/log/messages says;
line 1: this version of ISC DHCP is based on the release available line 2: features have been added and other changes line 3: have been made to the base software release in order to make line 4: it work better with this distribution line 5: please report for this software via the RedHat Bugzilla site: line 6: http://bugzilla.redhat.com line 7: exiting.
I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.
On my server Linux Redhat i want to configure dhcp server but when i check the dhcp status the dhcpd was stopped and i try to invoked or to start it failed. Even when open the graphical mode service configuration, check the box and click start the output error message is dhcp failed. the error: Starting dhcpd:Failed. How would i start the dhcpd service to run
I have a small office setup all on public ips and was trying to work out the best way to move the wearhouse computers on to private ips and leave offices on public ips I have server with 2 nics and i have two switches What i am after is how to set it up so all computers can still see each other but private can not access net All the office computers via switch 1 Public IPs All the wearhouse computers via switch 2 Private IPs
1 DHCP server 3 Routers from ISPs going to switch one Both switches going to DHCP Server
In my instructions for LAN boot, I am up to the next step :"You need the DHCP server software. If your distribution has none then you can use dhcp-3.1.3 and compile it."ok, so in F11 Live USB . . . I have downloaded and extracted files - they are still in Download directory . . .
Code: [root@localhost Download]# dir dhcp-3.1.3 dhcp-3.1.3.tar.gz
I am trying to set up a DHCP server for a network that does not go on the Internet using fedora 14. I have tried several site and every one I look at has a different dhcpd.conf file. I have tried many and every time I try to start the service they fail. Like I said it does not go on the Internet. No matter what I do when I try to start the dhcpd service it fails code...
I'm trying to move an existing webserver from an old machine to a machine with Fedora 12 installed on it. ThSince the version available in the repository is version 2.X I downloaded the source from apache.org and tried to compile it. I ran configure using the default options and it an without any warnings or errors. However when I run make it fails with the following error:
i have a project from my boss to make radius server on fedora 13 i 686. can u tell the step by step how to build radius server on fedora 13???? thx u for sharing

I start to build up IMPS to my server. Any ideas where to start? Any experience so far. I this think yamicocom like service. And about 5 bugs to get in. What you think? I need to put some extra to this basic concept.
I just got DHCP working, but I need to add a "Pre-Defined Option" for the Cisco VoIP network here. At least that's what it's called in Windows. This "Pre-defined Option 150" is necessary on Windows dhcp servers tied to Cisco VoIP networks, but I have no idea where to start getting that set up in Fedora.
Now when I try to pull an Ip from the 96.63.0.0/24 subnet I do not see the options in the DHCPACK from the server. The client gets an IP 96.63.0.12 but no options are present in the DHCPACK or any other DHCP transaction. I have confirmed this trhough tcpdumps on the server and client.
The server version I am using is:
The version of the DHCP server is :
Internet Systems Consortium DHCP Server V3.0.6-Fedora
I was wondering if and how it would be possible to put together a sort of Home "cluster" system. pecifically, I wanted to make it so I would have a central server and a few computers, where the central server holds the home folders and settings of each user, and each user can log in to any of the computers using a standardized login (into the server), where anyone could log in with their account on any of the few computers - and their home folder (Desktop, Documents, Music, etc) would automatically be there.
Also if possible, would there be some way to centralize the applications that show up on each "client"?
i want to install oscar cluster on my ubuntu 8.04 , so i added its repository from http://svn.oscar.openclustergroup.or...ki/repoTesting .i added repo from Testing the development version section.when i use oscar-config --bootstrap i receive this error :
Initializing ODA: mysql ERROR: Unknown ODA type () at /usr/bin/oda line 886[code]....
