Fedora Servers :: Put Together A Sort Of Home "cluster" System?
Mar 5, 2011
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 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.

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.

We are having a cluster with couple of disk servers, compute nodes and a head node. Disk server is nfs mounted on all the compute and head nodes.
The problem is that if any of the disk servers hangs, it freezes rest of the cluster too which is dangerous. Ideally, cluster should not care about the hanged server and run without any problem except files from that server is not visible.
Is there any way I could avoid the problem of freezing cluster because of one hanged server?

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 have made a cluster between two server.
In luci I can see that my cluster is green and the two nodes to.
I have make an IP resource and associate it to a service : green : I can relocate the service from a node to the other one and the IP appears in the list of IP addresses
The problem is that I have made the same in order to configure tomcat and postgresql and it does not work...
I put my configuration only for ip and tomcat:
My host configuration code...

HiI still have a issue where nautilus occasionally wont show my home folder's contents.
(it has no images or videos or music in the home folder directly (only in sub-folders), only other folders and text files, incl dot files for settings)
I have to reboot to get it to work.
Sometimes it does it right after a reboot, a 2nd reboot then allows nautilus to see contents of the home folder.
This thread was from F12 Beta stage, now closed:

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 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.

I installed netatalk for Linux in Fedora 10. I managed to get the service starting correctly at every boot and from Linux side everything looks good. I even manged to tweak avahi-daemon to advertise my server on the network so would show in Finder sidebar (with a snazy tux icon). But when I try to connect to the server it asks me for username and password (as it should), but my password doesn't work. I changed my password, I even gave it a simple one to rule out possibility of "fat-finger"-ing. No success.
I tried many options in my afpd.conf file. Here is the latest code...

Having a problem with my system hanging after updating Fedora 12. Here are my system specs:
Gigabyte MA770-UD3 motherboard
AMD Phenom 9950 Quad Core
6 gig Corsair DDR 800
1 x 160 gig SATA (OS)
1 x 500 gig SATA (data)
I have my system configured for dual boot with Windows 7. After installing F12, I can reboot with no problem. However, after I install the kmod-nvidia drivers, my system hangs on reboot. If I press any key on the keyboard, it will start to load, the freeze until I press a key again. I have tried both Fedora 12 x64 and i386 with the same results. Here are the steps that I took to install the kmod-nvidia drivers code...
Does anyone have any suggestions as to what I am doing wrong?

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 :
[Code]...
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 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

I tried the openssi for debian. I've tried linux from scratch but flopped trying to get mosix or kerrighed on it. Anyone got a simple way to go to get a hard drive installed single system image cluster with 32 bit machines. I'm not a new linux user but I have seemed to reach the limit of my skills. I don't like the live cds because I plan to add software later. The live cds don't fit my needs.

I have an ssh server running at home and I'd like to be able to connect to it from an internet cafe that wont let me run putty or java applets. Is there any way to ssh into my home machine through a browser? The only solutions I could find where java based.
In theory, would it be possible to open an ssh connection that reads and writes to a file, and then make a cgi script that writes commands to the file and formats the output to html?

I recently switched a computer running PCLinuxOS over to Fedora 12. I used to have PCLinuxOS set up as an SSH server so that I could quickly and easily share files with other computers in the house. Since the switch, other computers cannot connect to the SSH server unless I use sudo. I cannot set up a network connection in the GUI; "Unable to connect to server. Please check your settings and try again". Same thing happens if I use the ssh command without sudo. Is Fedora blocking something?
