Server :: Setting Up GFS2 On Centos5?
Nov 2, 2010
I am getting frustrated to the fact that I am in charge of developing a Enterprise class solution for my company and I don't find the right answer on the WWW. I have 3 mail servers that I want them to share a Global File System (GFS) that will be mounted via ISCSI on a RAID1+0 SAN Md3000i device. All the documentation that RHEL offers include the setup of DRDB or VLS Clustering.
My intentions are not to setup clustering on these servers, at least for now, however I want them to share access to the same block device, giving enough write/read access throughput . My question is, have you done something like this ? Do you know of any good Tutorial that you tried, and worked for you ?

I have configured the RHEL cluster suite in RHEL 5.3 64 bit, I have formatted a storage 100 GB LVM with GFS2 filesystem with lock_dlm protocol default journel I have used 8 I have also added this filesystem in cluster resource in GFS resource option, all work fine cluster is able to remount this GFS2 LVM on another node in time of failover. But when I was checking cluster configuration file (/etc/cluster/cluster.conf) in resource syntex it was showing fs_type=gfs so my query is if it uses fs_type=gfs then is it also mount my formatted gfs2 lvm as gfs filesystem in my cluster node rather then gfs2 filesystem. Also how do i check that mounted filesystem is gfs or gfs2, Please clear my doubt.

I'm trying to recover a GFS2 partition on a SAN that was connected to a server that was recently kickstarted with the "clearpart -all -initlabel". Is this possible? The volumes are quite large (20TB). I'm currently in the process of using parted's rescue feature but so far that has been unsuccessful.
Here's some output from my system:
Number Start End Size File system Name Flags
Nothing?

I am hosting apache service on the CentOS5.4. I configure the Apache in default setting mostly. But keep getting complaints from others about the website download too slow, pdf cannot download at all, flash cannot play smoothly, etc.. But on my own machine, everything works fine. Is there any tool for analyzing this problem?

To clustering my web server so that it becomes Highly available. Its currently running php, apache and mysql with no redundancy in place. I want to be clustered so that if one node goes down then the second one will automatically take over. I have done that with HA in RHEL but I want to use centos clustering solution for this. Also how willl they share the web contents and mysql database among two nodes I have no idea. I have managed a iscsi target to store contents but it doesn't work as expected.

Used to work fine, mybb forums and a blog, accidentally chowned everything to wrong account, then back to root, fixed mysql, shell and php and it got back up again yesterday, made a new database and updated some packages using webmin (OpenSSL etc), tried to install virtualmin but qMail blocked it, few hours later out of the blue all our php files download as .bin files, as downloadfile.bin on my android phone but others on our game server reported it downloading too.
We shut off apache for obvious security reasons and are considering to close shop if we cant fix this.

I have installed apache tomcat 5.5.27 in centos5. I edited the server.xml file also. The startup.sh and shutdown.sh commands are working fine. But tomcat is not opening in the browser. Can you suggest me something or tell me the steps involved in installing tomcat. Is admin.tar.gz of apache tomcat required for its working?

I'd like to build a server to run CentOS5 to host domains & run Boonex's Dolphin 7. I can't afford the hardware at present, but do have a spare laptop to test with. My two questions:
1) Is is possible to create a build on my laptop, with CentOS, PHP, Dolphin 7, DNS etc, and then create an image to transfer to the future hardware server when constructed? If not, are there alternatives e.g. to copy settings, and then paste then onto the new CentOS install? Anything else I should consider for doing this future move?
2) I presume it's not possible to transfer from 32bit (now) to 64 bit (possibly later) CentOS5?

I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
test problem:
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).

I have lack of understanding of CentOS in general. I have looked for a remedy on other forums and google, but haven't been able to find the answer. I have a 3 node cluster that was functioning great until I decided to go offline for awhile. My config is as follows:
node 2: vh1
node 3: vh2
node 4: vh6
All nodes connect to a common shared area on an iscsi device (vguests_root)
Currently vh2 and vh6 connect great, however since putting the machines back online I can no longer connect with vh1. A dmesg command on vh1 reveals the following:
GFS2: fsid=: Trying to join cluster "lock_dlm", "Cluster1:vguest_roots"
GFS2: fsid=Cluster1:vguest_roots.2: Joined cluster. Now mounting FS...
GFS2: fsid=Cluster1:vguest_roots.2: can't mount journal #2
GFS2: fsid=Cluster1:vguest_roots.2: there are only 2 journals (0 - 1) .....

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 using CentOS5 and installed the MySQL for server during the installation. I can set up and use MySQL databases. But I cannot make it startup everytime the server restarts. And quite a lot of methods need this folder "support-files/mysql.server", while my set up cannot find this. I am wondering if my installation of the MySQL for server is complete or not.

Because our visitors/customers are short term, and may be configured incorrectly with their own mail servers we automagically redirect all port 25 traffic going to internal IP's to our own mail servers while on our network.(postfix on centos 5.6)While I have taken some measures to prevent it from spamming, I would greatly appreciate some assistance.I will be putting in clamav, but I haven't configured it yet with the mail.I am using postfix, but can also put on procmail or even spam assassin

Having some issues setting up sendmail on a (basically) blank RHEL 5.5 server setup. My ultimate goal is to be able to automagically send logs / errors / notifications to ourselves from the server.
Our basic setup is a Win 2003 domain with exchange running on mail.domain.com.au.
I've edited the '/etc/mail/sendmail.mc' and added the :
Code:
line to it.
Also added the domain (domain.com.au) to the '/etc/mail/local-host-names' files
Also edited submit.mc and added
Code:
When I try and send a mail from root or a test user to one of the domain accounts, it seems to go fine, i.e no errors are reported but it never gets delivered.
From the mail logs:
Code:
So it seems to be sent to the queue no problems and when I check the queue :
Code:
Total requests: 0
Not nothing ever gets received. Am I missing something? I have read and read and read but dont seem to be getting any furthur.
So in the end this server doesn't need to do anything except be able to send mail from root to an external mail address.

I was using Red Hat 7.3 forever and decided it was time for a change. I went to Fedora 10 but it was really buggy. CentOS 5.2 is VERY stable.Here is my problem.The server is command line only -- I tend to hate GUI"S.I setup Samba no problem disabling the ports needed through the firewall and that was straightforward.CUPS is a nightmare for me since CentOS locks down the cupsd.conf and then the firewall does its thing. I allowed port 631 through the firewall but then got lost on the cupsd.conf. It's been too long and the old redhat one won't work with CentOS (not surprising since it's a VERY old system) straight-forward CUPS tutorial for a command line interface. I just need it to be:
a) do this
b) do that

I need to grant windows client an access to fileserver. The easiest way to do it is how? Setting up VPN server on Windows server, what rules are going into iptables in linux machine then. Or setting up VPN server on Linux machine (which is the best option) and how the user gets to fileserver?

I have a need to set up the program TNG - The Next Generation of Genealogy Sitebuilding and run it on a local server (not on the Internet) for the purpose of learning the system prior to developing it on an actual website. I was told to use http://localhost on my browser (Mozilla Firefox). I get a message saying "That Works!", but it goes on to say that the contents of the web server have not yet been entered. The instructions for the downloaded files (which I unzipped) said to copy to the web root folder (the folder where the web server is located ?, I guess). But I don't know where it is or how to go about it. Can someone help? I already have MySQL and PHP, which are required to run this program, and I also have Apache installed on my Kubuntu 9.10 system.
