reading vdump files?
by Smithies, Russell 20 Sep '11

20 Sep '11

I have a lot of data in some vdump files backed up from a Tru64 system that I now need to recover to a Centos server. We no longer have any servers running Tru64, is there any way to extract/convert them on a "standard" linux system? Ideally converting in bulk to a tar would do. Any ideas?

Can't boot Centos6 ext4 partition from GAG bootloader
by Maurice Batey 19 Sep '11

19 Sep '11

Have just installed Centos-6 from a Linux Format DVD. The install went smoothly, although the installer inisisted that the root partition had to be formatted ext4. When my GAG boot loader tried to boot from that root partition, it was unable do so. Elsewhere I read that GAG cannot boot from an ext4 parititon. I there any way tp persuade Centos-6 to use an ext3 root partition? -- /\/\aurice (Retired in Surrey, UK)

questions about upgrading
by Jon Detert 19 Sep '11

19 Sep '11

I'm pretty new to the task of upgrading CentOS or RedHat o.s.'s. I'm more familiar with upgrading Debian based o.s.'s. Here are my questions: 1) will yum ever upgrade the major version? I understand that there is no upgrade path from v5.x to v6.x, but is that always the case? e.g. was there an upgrade path from v4.x -> v5.x? If yum is capable of doing so, what are the command-line arguments necessary? 2) can I upgrade a minor version to any other greater minor number, or only to the greatest? E.g. if i have a v5.4 box, can i upgrade to v5.5 or v5.6, or only to v5.7 (currently the latest)? 3) if an upgrade delivers a new kernel, am I obligated to run it (i.e. will the old kernel remain installed, or will the upgrade remove the old kernel)? If not, does the upgrade automatically update grub such that the new kernel becomes the default? Will the upgraded box function properly without running the new kernel? 4) aside from when an upgrade includes a new kernel, how can I tell when a reboot is necessary? I gather that a new glibc may require services to be restarted, but is a reboot strictly necessary? 5) is there a way to apply only the updates that were made for the given minor version you're currently at? E.g. if I'm at v5.5, how can I only apply updates that were made prior to v5.6's availability? Thanks, Jon

CentOS and Scientific Linux Cern installations with FAI
by lange＠fai-project.org 19 Sep '11

19 Sep '11

I'm very happy to announce, that FAI (Fully automatic Installation) now can install and configure CentOS and Scientific Linux Cern (SLC). You can use a Debian FAI server for installing CentOS version 5 and 6 or SLC 5 and 6. As an example I've also built a FAI multi-distribution CD which installs those three different Linux distributions with different configurations. Get this ISO image from http://fai-project.org/fai-cd/ This installation is very quick. I've done a CentOS 6.0 installation (with graphical desktop) in 199 seconds (in a kvm instance on a quad-core 3.2GHz, hard disk in RAM) and it only needs 490 seconds on the real hardware when installing from CD. A short description how to install CentOS or SLC via network from your FAI server is described in this mail: https://lists.uni-koeln.de/pipermail/linux-fai/2011-September/009243.html Feedback is always welcome. Please send your feedback to the linux-fai mailing list https://lists.uni-koeln.de/mailman/listinfo/linux-fai/ Best regards, Thomas, in behalf of the FAI team About FAI: FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large infrastructures and clusters. Compared to kickstart, FAI is more flexible and includes a powerfull class mechanism to build a configuration from multiple building blocks. It also includes the features of cobbler. The project was started in 1999 for the Debian distribution. Later Ubuntu support was added and some time ago we start adding RPM support.

javaWS under firefox on CentOS 5.6 fails to launch sound
by Rob Kampen 18 Sep '11

18 Sep '11

Hi List, Before I spend hours chasing this - my initial google search seems to indicate that javaWS and JNLP apps with sound do not work on CentOS systems. The developer's website says they support :- *Linux* *Supported OS’s and recommended versions of Java* * Linux o openSUSE 11 (64 bit with 64 bit JVM) o Ubuntu 9.10 (64 bit with 64 bit JVM) * Pentium III 1 GHz processor * Sun Java 1.5.0_17 or Sun Java 1.6.0_12 or greater is recommended I have Oracle's java v1.6.0_26 installed - the java app opens up and appears to be functioning fine, however the wizard for setting up the sound, even though it recognizes my sound card fails to actually play any sound. Running latest 5.7 [rkampen@robsws ~]$ uname -a Linux robsws.ndgonline.net 2.6.18-238.19.1.el5.centos.plus #1 SMP Mon Jul 18 10:05:09 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux [rkampen@robsws ~]$ rpm -qa |grep firefox firefox-3.6.18-1.el5.centos.x86_64 Sound from within other browser based apps (flash etc) work just fine. Anyone got a javaWS with sound application working on CentOS? TIA - Rob

Depsolving errors whilst upgrading Centos 5.6 -> 5.7
by Dave Cross 18 Sep '11

18 Sep '11

I have a dedicated server from 1&1 (http://1and1.co.uk/) A 'yum list updates' today showed me that the 5.7 update was available (it's probably been there for a while, I don't check that often). But running 'yum update' gives the following error: Running rpm_check_debug ERROR with rpm_check_debug vs depsolve: kernel(rhel5_fs_proc_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_arch_x86_64_kernel_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_partitions_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_vmlinux_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_drivers_xen_core_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_block_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_security_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_block_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_kernel_module_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_fs_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_mm_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_lib_ga) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 kernel(rhel5_mm_u2) is needed by (installed) kmod-xfs-xen-0.4-2.x86_64 Complete! (1, [u'Please report this error in http://bugs.centos.org/set_project.php?project_id=16&ref=http://bugs.centos…']) I haven't reported the bug yet. I thought I'd see if anyone here had seen anything similar first. Cheers, Dave... -- Dave Cross :: dave(a)dave.org.uk http://dave.org.uk/ @davorg

centos product specification
by Janez Kosmrlj 18 Sep '11

18 Sep '11

The page http://www.centos.org/product.html has product specifications for all centos releases except for centos6. Is there a reason why or did the site maintainers just forget about it.
