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.
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 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.
Using google with search option: cman not started: Can't find local node name in cluster.conf /usr/sbin/ cman_tool: aisexec daemon didn't start.I found this URL...I have found the config_version in cluster.conf. Unfortunately, as everyone may have noticed, english is not my native tongue so I am having trouble understanding the part "Make sure you bumped the cluster config version number". Can anyone enlightened me on what should I be doing so that I could "bump" the cluster config version?
what rpms should I need install for setting up redhat cluster on RHEL 5.0 I want to create two RHEL 5.0 nodes as one cluster having oracle database server installed. And please note I have created these two nodes on VMware server for testing purpose. is it possible for creating cluster of two virtual guests.
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
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.
I'm trying to recover movie files from my TNT receiver hard drive but it corrupts its FAT32 allocation table (crappy cheap device...)
Using dosfsck is useless because the correct file length is the cluster length, not the (shorter) one in the table, and dosfsck only proposes to shorten the file, which I won't do.
Question: how to recover a file using the FAT cluster chain instead of using the stored length in the FAT table?
I have just installed sendmailanalyzer to my centos 6 by using rpm package. But before, i tried to install it by perl.There is no problem now everything works but when i want to configure i see that there are lots of conf file. How can i see a conf file of service "sendmailanalyzer" what is the command ?
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 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 need advice in getting the original blacklist.conf of the directory /etc/modprobe.d/ because I erased and I don't know if that file could make me have some issues in the future, so if any body can lend me a copy of that file or refere me to some page where i can get it. Is for the slackware 13 32bits distro.
I've just done a fresh install of Lubuntu 10.10 on an older Sony Vaio laptop. Having learned the hard way about editing xorg files, I wanted to create a backup of the xorg.conf file so that I dont have to do another install when I screw everything up. In a terminal, I typed
accidentally I do something wrong with my server and the httpd folder missing and I need it to setup my mail server and anyone can help me what can I do without reinstalling my Cent OS? Here is the error msg :
[root@mydomain etc]# service httpd stop Stopping httpd: [FAILED] [root@mydomain etc]# service httpd restart
But the idea is that I can add a line to a section and it check if the section is defined, (add the definition if not), the property is defined, let it undefine (erase the line), (and delete the section header if there is no property defined), etc...
I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).
there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.
I am installing some SSL certificates on my web server, however I have a couple questions, as I'm not familiar with this process
1) I'm not sure which directory to put them in? What is good practice? Is /var/www/secure a good location so long as I restrict access to the secure directory?
2) I am told to edit the following in my ssl.conf file of apache2
However, I cannot find this file, ssl.conf. Nor can I find the above directives in my main apache2.conf file. Where is the ssl.conf file? Or alternatively, could I just add the above directives to my apache2.conf file?
I just installed 11.2, and discovered when I went to setup my Logitech Marble Trackball, that there was no /etc/X11/xorg.conf file. After some Googleing, I created one using sax2, Edited it to add the appropriate parameters to enable scrolling using the ball, and all works great.
My question is if there is a more "correct" way to change the parameters, as the mouse parameters are obviously stored somewhere on the machine.
BTW, for those with a Marble Trackball, all you need to know about the xorg.conf setup can be found here:
I am setting up a display system that will not have a keyboard/mouse and automatically boots into gnome and starts up firefox to a display page. The page is optimized to a 720p resolution which I can set when we use a TV for the display, but is not an option if we use a monitor. I am trying to find a way to set the resolution to 720p automatically on boot up. I am always using 16x9 displays with a DVI connection (to HDMI on TVs)
I was able to get one monitor working by creating a script and setting it to load in the Startup Applications as shown:
Using Debian Lenny.I am new to printing with Linux and would like some help with CUPS. I have CUPS set up to work with my printer.I read through the documentation, but still have some problems.
1. How should I configure cupsd.conf for security?
Quote:
Portwalling
* By default, cups will listen on every interface. Unless you want to offer your printer to the world, you must block this.Although you can firewall this (and that is a good idea anyway),you can also not have cups listen on your Internet connection.This also prevents any possibility of a root exploit from the Internet. Of course, you still have internal crackers to worry about...
* In cups.conf, comment out the lines: Port 80 Port 631 * Replace them with: Listen 127.0.0.1:631 code....
How do I create a symbolic link between programs?When I opened Xpp it said Printer:destination not available.
4. Can I adjust the text size on text, pdf or html files with Cups or do I need another program for this?
I am running Red Hat Linux Enterprise 5; I am always using the export command to set environment variables.Are there any other ways to set environment variables and what are the advantages/disadvantages of them?
