Hard disk installation
by Timothy Murphy 12 Jul '11

12 Jul '11

Has anyone installed CentOS-6 from the hard disk? I just tried this without success. I should say that I asked the question before about CentOS-5.6, and while I got many suggestions in reply, no-one actually said that they _had_ installed CentOS this way. What I did was to "mount -o loop" the DVD iso (which I checksum-ed) and copy isolinux/vmlinuz and isolinux/initrd.img , as well as the images/ directory, to /boot , and then added a simple stanza ------------------------ title CentOS-6 root (hd0,1) kernel /vmlinuz text askmethod initrd /initrd.img ------------------------ The machine - I should have said that it is an HP MicroServer - boots fine, until it gets to "Waiting for hardware to initialize", at which point the screen goes blank and nothing appears to happen. I should say that the machine is running under CentOS-5.6, which I installed with a USB stick. I'm trying to install CentOS-6 on another partition. I shall try the USB stick method shortly. But I would be interested to know if anyone has actually installed CentOS-6 from the hard disk, and if so how. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Updates... What? already?
by Mark Weaver 12 Jul '11

12 Jul '11

Just had a good laugh. I'm sitting here at my desk working with my laptop sitting off to the side; I've just loaded C6 this morning and as I understand it C6 _just_ finished syncing on the mirrors over the weekend. I look up from an email I'm composing to see the updates alert being displayed. I won't repeat what first entered my head, but I couldn't help but laugh and think, "How the hell can there be updates already for an OS that just got released?" -- Mark Weaver Computer Information Systems & Services, Inc. mweaver(a)compinfosystems.com (717) 512-9718

Hi List, This morning while setting up C6 on my laptop this morning I attempted to download and install Yumex, but the repos returned no results for this package. Has this been discontinued and if so, what package manager should I be looking for? thanks, Mark

Deleting a KVM virtual machine from the command line
by Sean Carolan 11 Jul '11

11 Jul '11

I am working on a sandbox machine that will allow users to play around with building virtual machines, then blow them all away each night with a cron job. I wrote a small script that uses the virsh command to destroy the VMs, then remove the storage. For some reason the vm name still shows up in the virt-manager GUI. Anyone have an idea how you delete it from there as well, without using the GUI? thanks Sean

CentOS 6 and pxeboot
by m.roth＠5-cent.us 11 Jul '11

11 Jul '11

Well, I started the install, got pxeboot to get to the kickstart file, formatted the drive... and then it failed, telling me "unable to read group information from repositories. This is a problem with the generation of your install tree." A quick google gives me the first hit from a year ago, bug 4372 <http://bugs.centos.org/view.php?id=4372>, which says there's a metadata problem. Has anyone else run into this today? mark

how to enable Flow Control on CentOS?
by Rudi Ahlers 11 Jul '11

11 Jul '11

Hi, I have an interesting situation with one of our switches. It's a D-Link DGS-3100, 24 port 10/100/1000 Layer 2 Managed switch with some CentOS servers connected to it. On many of the servers I need to disable Flow Control on the switch's ports otherwise the CentOS server's doesn't connect to the switch. i.e. the Switch indicates that the LAN cable is unplugged and CentOS can simply not connect to any host on the LAN. As soon as I disable Flow Control, CentOS "breaks". Does anyone know why this would happen, or how / if I can enable Flow Control in CentOS as well? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

centos 6 boot and install on hp dl380 G4
by Florian 11 Jul '11

11 Jul '11

Hello List, i downloaded centos6 x86_64. With DVD-iso1 i made a booteable usb-stick (universal usb installer 1.8.5.7). When i boot my HP ProLiant DL380 G4 from the stick, the CentOS boot screen comes up and and the message "Automatic boot in xx seconds..." appears. * When i do not hit any key, the seconds are counted to zero an then it starts again at 10 seconds - again and again. * When hitting return, a boot menu appears: 1) Boot 2) Boot (text mode) 3) Network Installation 4) Memory-Test 5) Boot from local drive Only Options "Memory-Test" and "Boot from local drive" work. When choosing Option 1,2,3 i'm always pushed back to the menu. How to install CentOS vom the stick? Please help me to find my mistake. Please tell me, if i can provide any information. Bye, Florian

WOW!!! I'm actually stunned. I was expecting some changes, but this is wonderful and EVERYTHING worked correctly right out of the box. Having a few small issues with my touchpad on this Dell Inspiron - can't get it to scroll - but everything else is exquisite! Thank you SO much for all your hard work CentOS team. -- Mark Weaver Computer Information Systems & Services, Inc. mweaver(a)compinfosystems.com<mailto:mweaver@compinfosystems.com> (717) 512-9718

Today's Topics: 1. Release for CentOS-6.0 i386 and x86_64 (Karanbir Singh) ---------------------------------------------------------------------- Message: 1 Date: Sun, 10 Jul 2011 19:51:21 +0100 From: Karanbir Singh <kbsingh(a)centos.org> Subject: [CentOS-announce] Release for CentOS-6.0 i386 and x86_64 To: CentOS Announcements List <centos-announce(a)centos.org> Message-ID: <4E19F4A9.1050204(a)centos.org> Content-Type: text/plain; charset=ISO-8859-1; format=flowed We are pleased to announce the immediate availability of CentOS-6.0 for i386 and x86_64 Architectures. CentOS-6.0 is based on the upstream release EL 6.0 and includes packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with. There are some important changes to this release compared with the previous versions of CentOS and we highly recommend reading this announcement along with the Release Notes at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0 There are no CD images being released with CentOS-6, however we have some CD variants in the pipeline. Details for these are mentioned below. Since upstream has a 6.1 version already released, we will be using a Continous Release repository for 6.0 to bring all 6.1 and post 6.1 security updates to all 6.0 users, till such time as CentOS-6.1 is released itself. There will be more details about this posted within the next 48 hours. +++++++++++++++++++++++ Upgrading from CentOS-4 or CentOS-5: We recommend everyone run through a reinstall rather than attempt an inplace upgrade from CentOS-4 or CentOS-5 +++++++++++++++++++++++ LiveCD and LiveDVD LiveCDs and LiveDVDs for i386 and x86_64 will be released within the next few days. These will bring in the ability to directly install from the livemedia. +++++++++++++++++++++++ Minimal Install CD We have also created a minimal install CD, that would bring up a base machine with just enough content to have a usable platform. This CD image will be released in the next few days. +++++++++++++++++++++++ The LightWeightServer (LWS) CD In order to bring back the CentOS-4 Server CD style single iso image, we are creating a LWS varient of the main distro. Details for this will be posted in the next few days with release happening after the live media and the minimal cd editions. +++++++++++++++++++++++ Downloading CentOS-6.0 for new installs: When possible, consider using torrents to run the downloads. In most cases you will find its also the fastest means to download the distro. There are currently over a thousand people seeding CentOS-6 and it's possible to get upto 100mbps downloads via these torrents. Torrent files for the DVD's are avilable at : http://mirror.centos.org/centos/6.0/isos/i386/CentOS-6.0-i386-bin-DVD.torre… http://mirror.centos.org/centos/6.0/isos/x86_64/CentOS-6.0-x86_64-bin-DVD.t… You can also use a mirror close to you : http://www.centos.org/modules/tinycontent/index.php?id=30 Most mirrors will allow direct DVD downloads over http, ftp and rsync. Please keep in mind that not all mirrors are currently updated, some might take upto another 24 hours before they have all the content. +++++++++++++++++++++++ sha1sum for the CentOS-6.0 ISOS: i386: fcf49e875cd4494f2af68cf257ab9e93523c9427 CentOS-6.0-i386-bin-DVD.iso 862815623d2e7990207dd78a281837c7eb719e83 CentOS-6.0-i386-netinstall.iso x86_64: 9de87b0c696ebd72b952edb4cc06c24cbdc37d81 CentOS-6.0-x86_64-bin-DVD1.iso 5e3834621f11fbcca78cf7d70625c647045f45f5 CentOS-6.0-x86_64-bin-DVD2.iso 23f9e606cbcbd52d2e5df3716a85cdde336f7bfe CentOS-6.0-x86_64-netinstall.iso +++++++++++++++++++++++ Sources and Debuginfo packages: SRPMS and debuginfo packages are still making their way to the CentOS mirrors and should be available within the next 24 to 48 hours. We are prioritising the centos modified packages. +++++++++++++++++++++++ Getting Help: The best place to start when looking for help with CentOS is at the wiki ( http://wiki.centos.org/GettingHelp ) which lists various options and communities who might be able to help. If you think there is a bug in the system, do report it at http://bugs.centos.org/ - but keep in mind that the bugs system is *not* a support mechanism. +++++++++++++++++++++++ Contributing and joining the project: We are always looking for people to join and help with various things in the project. If you are keen to help out a good place to start is the wiki page at http://wiki.centos.org/Contribute . If you have questions or a specific area you would like to contribute towards that is not covered on that page, feel free to drop in on #centos-devel(a)irc.freenode.net for a chat or email the centos-devel list (http://lists.centos.org) +++++++++++++++++++++++ Thanks to everyone who contributed towards making 6.0 Enjoy! -- Karanbir Singh <kbsingh(a)centos.org> The CentOS Project {http://www.centos.org} irc: z00dax(a)irc.freenode.net ( #centos, #centos-devel ) ------------------------------ _______________________________________________ CentOS-announce mailing list CentOS-announce(a)centos.org http://lists.centos.org/mailman/listinfo/centos-announce End of CentOS-announce Digest, Vol 77, Issue 4 **********************************************
