Not a CentOS specific question, although I am running grep on CentOS 4.3 but how would you grep out a series of lines in a file starting at a specific point. For instance, if I have a file named foo and I want to grep out the next 5 lines after the first and only instance of the string "bar" how could I pull that off? Thanks so much.

Just installed CentOS 5.1 on VMware ESX and am attempting to play with the newly added tick_divider feature. It doesn't seem to be making any difference in the number of timer interrupts though. I set tick_divider=10 which should reduce the number of timer interrupts to 100. I wrote a nasty little scripts that queries /proc/interrupts every 1 second and still see an increase each second in

We have two virtual machines on ESX 3 running CentOS 4.3 and we'd like to turn them into some sort of highly available nfs file server. Currently, I am familiar with DRBD and RHCS but I was curious what others might recommend in such a situation. I'm not sure how easily we could use RHCS in such a situation because we don't really have the advantage of shared storage in this setup.

Now that the csgfs repo has been updated to support the new kernel, I'm looking at doing updates again. I just want to do it without breaking things (if possible). I can handle doing a bit of trial and error, but I figure that if you guys can point out any obvious pitfalls, that can save me quite a bit of time. I'm looking at doing the following install/update:

I've been trying to build a model cluster using three virtual machines on my home server. Each VM boots off its own dedicated partition (CentOS 7.3). One partition is designated to be the common /home partition for the VMs, (on the real machine it will mount as /cluster). I'm intending to run GFS2 on the shared partition, so I need to configure DLM and corosync. That's where I'm

Hello fellows, I have a problem with a 2 node RHCS cluster (CentOS 4) where node 1 failed and node 2 became active. That happened already last year and due to holidays the customer didn't recognize it. The cluster is just a failover for Apache and has no shared storage space. Customer now saw the situation, tried to fix it by rebooting node 1, which then failed to come back up. As

Hi list, I've been trying to update my csgfs stuff to 4.7 this week but I notice that current csgfs is built against kernel-2.6.9-78.0.1 and is required as a dependence, right now current kernel is 2.6.9-78.0.5 it would be great if csgfs can be rebuilt or updated to this, so dependences works ok??? Best regards

I just took a brand new CentOS 4.2 x86_64 install, updated all of the base packages with yum, and then added the csgfs repo and attempted to install those packages. When I do the installation, I have a problem with one package: # yum install perl-Net-Telnet [ snip ] ============================================================================ = Package

Announcing CentOS 3 i386 Cluster Suite (CS) and Global File System (GFS) CentOS csgfs is now available for CentOS-3 i386. This is a built from source found here: ftp://ftp.redhat.com/pub/redhat/linux/enterprise/3/en/RHCS/i386/SRPMS/ ftp://ftp.redhat.com/pub/redhat/linux/enterprise/3/en/RHGFS/i386/SRPMS/ ftp://ftp.redhat.com/pub/redhat/linux/updates/enterprise/3AS/en/RHCS/SRPMS/

Let me QUICKLY say I'm not complaining here, but is the csgfs repository not being actively maintained? The Red Hat ftp site has much newer versions available than what is currently in the CentOS csgfs repo, at least for the kernel modules. Should I just go ahead and rebuild them from the SRPMs myself, or is this an unintended condition? This has been holding me up from upgrading to the

Centos CSGFS is at this time really outdated compared to current rh updates and fixes, is the centos team still giving support to this version???. Best regards

I've googled for this, but everything I find tends to talk about cluster and doesn't give an example close enough that I can figure this out. I have read the Red Hat Cluster Suite Configuring and Managing a Cluster <http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/> links from http://www.redhat.com/docs/manuals/csgfs/. (I think these are mirred on centos.org, but I

The CentOS Development Team is pleased to announce the release of the Cluster Suite 4 (CS) and Global File System 6.1 (GFS) for CentOS-4 for the i386 and x86_64 architectures.

I did a yum install of modules from the CentOS-csgfs repository (GFS-kernel, cman-kernel, etc). Modprobe does not find the modules. Upon investigation, I found that modprobe is looking in: /lib/modules/2.6.9-22.0.1.ELsmp/ while the package files were installed to: /lib/modules/2.6.9-22.0.1.EL/ Can I tell modprobe to use those modules somehow? Are modules for the smp kernel available? Or do I

This is an x86_64 system that I just updated from 4.2 to 4.3 (including the csgfs stuff). When I watch the bootup on the console, I see an error: lvm.static: symbol lookup error: /usr/lib64/liblvm2clusterlock.so: undefined symbol: lvm_snprintf This error comes immediately after the "Activating VGs" line, so it appears to be triggered by the vgchange command in the clvmd startup

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

Hello I read about the technology and i found all amazing and great challenger, i like to test and install soon---, for this reason i have some question about this.
