similar to: GFS & Vsftpd? maybe even Iscsi?

To extend space on our 64-bit centos FTP servers, we are considering setting them up to work with an existing PromiseRAID system via iscsi. -just curious if anyone here knows if iScsi is fast enough to serve up all the images? -might it be something where we get dedicated cards and put the iScsi traffic on its own Vlan? Just curious if this would hold up under alot of traffic, like weather

We currently have a MD3000i with an iSCSI LUN shared out to our apache web server. We are going to add another apache web server into the mix using LVS to load balance, however, I am curious how well iSCSI handles file locking and data integrity. I have the iSCSI partition formatted as ext3. Is my setup totally flawed and will ext3 not allow for data integrity with multiple apache hosts

Hi all, I'm wondering if I'm running into some dependency issues on my CentOS5 test-machines. I've installed with a fairly minimal package set, updated, removed old kernels and am now experimenting with iscsi and gfs. I think I need kmod-gfs to get gfs -support, but there is only a version that suits the base-kernel, 2.6.18-8.el5. " [root at node02 ~]# yum install kmod-gfs

HI, Sorry for repeating same mail ,while composing that mail i mistakenly typed the send button.I am facing problem with my gfs and below is the running setup. My setup Two node Cluster[only to create shared gfs file system] with manual fencing running on centos 4 update 5 for oracle apps. Shared gfs partition are mounted on both the node[active-active] Whenever i type df -h command it

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs. [root at node2 ~]# cman_tool status Version: 6.2.0 Config Version: 29 Cluster Name:

Two web servers, both virtualized with CentOS Xen servers as host (residing on two different physical servers). GFS used to store home directories containing web document roots. Shared block device used by GFS is an ISCSI target with the ISCSI initiator residing on the Dom-0, and presented to Dom-U webservers as drives. Also, providing a second shared block device for quorum disk. If I hit the

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5

Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested

Hello: I am planning to implement GFS for my university as a summer project. I have 10 servers each with SAN disks attached. I will be reading and writing many files for professor's research projects. Each file can be anywhere from 1k to 120GB (fluid dynamic research images). The 10 servers will be using NIC bonding (1GB/network). So, would GFS be ideal for this? I have been reading a lot

Hi everyone! I have 2 hosts + 1 ISCSI device. I want to create a shared storage repository and both hosts use together.

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

Hello list, I want to use shared volumes between severall vm''s and defenetly don''t want to use NFS or Samba! So i have three options: 1. simulated(software-) iscsi 2. GFS 3. OCFS2 What do you suggest and why? Kind regards, Florian ********************************************************************************************** IMPORTANT: The contents of this email and any

Are the RPMs for the latest GFS kernel module GFS-kernel-2.6.9-72.2.0.8 to be used with the version 2.6.9-55.0.9.EL available ? I tried to compile the Source RPMs available from the Red Hat site but the modules can't be loaded because of invalid module format arising from version magic issues. The syslog shows: node0 kernel: gfs: version magic '2.6.9-55.0.9.ELsmp SMP 686 REGPARM

Hello, We have two Fedora 5 Servers clustered with GFS. We installed samba and exported the same shares in both of them. All went fine at first, with people accessing to theirs own files and so, but for some programs (minitab, matlab, ...) people need to access the same file at once. Then samba begins to fail and clients hang. In order to fix samba is necessary to restart the service.

Hi all, Since I've got no reply on redhat cluster list, I'm trying here ... I'm testing a rhcs4 cluster with gfs. I noticed some poor performance while tarring data from a gfs volume to a local disk from both nodes at the same time, so I deceided to have a closer look. Here are the bonnie++ results: http://jure.pecar.org/gfs/ I don't know what to think of these ... but I doubt

On CentOS 5, the current centosplus kernel doesn't want to play with the kmod-gfs package (because kmod-gfs wants the stock kernel): # yum install kmod-gfs gives me: Transaction Check Error: package kernel-2.6.18-8.1.14.el5.centos.plus (which is newer than kernel-2.6.18-8.1.14.el5) is already installed Should it work, or is there a separate centosplus build that I've not

Hi anybody! I'm not shure if this really is a rsync problem, it might also be a shell issue. But hopefully, someone has a hint for me ;-) I'm using rsync 3.0.9 on two OS X Servers (FreeBSD) to synchronize several folders between both servers (2-way-sync). Works fine, with one exception: One of the directories to be sync'd contains a whitespace in its pathname, and this one only

Hello there! I made Debian, Xen 2.0 and CLUSTER/GFS work together :). I wrote this little tutorial to help you setup yours. Any feedback is welcome, except comments about W3C validation of my code :p Note that I am talking about compiling CLUSTER with your XEN kernel, I don''t explain how to setup a working cluster. You can find how to setup those in official RedHat docs. You will see,

Hey All, I have a cluster setup and exporting gfs storage everything is working ok(as far as I know anyway). But instead of mounting the gfs storage I want the xen guest to be installed on the shared gfs storage. But with my current setup when I install the domU on the gfs storage it changes it to ext3. Is it possible this way or does the domU have to be on an ext file system?

Hi all, We are running CentOS 5.2 64bit as our file server. Currently, we used GFS (with CLVM underneath it) as our filesystem (for our multiple 2TB SAN volume exports) since we plan to add more file servers (serving the same contents) later on. The issue we are facing at the moment is we found out that command such as 'ls' gives a very slow response.(e.g 3-4minutes for the outputs of ls
