The filesystem on /dev/sda1 does not at any time contain anything useful (it started out as just being an extended partition, and now is completely empty. At no time did it have any label set).

CentOS 5 single DVD for i386 and x86_64
by Luciano Miguel Ferreira Rocha 01 May '07

01 May '07

Hello, I'd like to announce a release of a CentOS 5 DVD image, with i386 and x86_64 installations. This is an independent work, so please don't bother CentOS lists with bugs related to the installer only. Summary of changes: * i686 and x86_64 install from a single dvd (automatic detection on boot) * updates as of 2007-04-26 * no kdelibs-api-docs, openoffice.org, tetex-doc and most *-javadoc sha1sum: 63885249695c60a87443e304212d6cf9af678165 centos5_32and64.iso md5sum: 0db291c3e4f7dc4fb4e6ea052b77e95d centos5_32and64.iso torrent: ftp://ftp.gil.di.uminho.pt/pub/users/strange/centos/c5_32+64.torrent iso: ftp://ftp.gil.di.uminho.pt/pub/users/strange/centos/centos5_32and64.iso Detailed changes: * All rpms are the originals from CentOS 5. However, the *.i386.rpm and *.noarch.rpm for the x86_64 are the ones from the i386 DVD, not from the x86_64, as the contents are the same and the rpm headers differ only on the Build Date and/or Signature. * each install (x86_64 or i386) only has knowledge of rpms originally in their DVDs, so x86_64 installs won't be bloated with more i386 packages than the originals. * Some packages are missing. It's a pity some subpackages that don't depend on %arch are still built as .%arch.rpm, but there's nothing I'm willing to do about that. The missing packages are: - openoffice.org - tetex-doc - kdelibs-apidocs - Deployment_Guide, except for en_US and pt-BR - *-javadoc, except for: - java-1.4.2-gcj-compat-javadoc (required by eclipse) - bsh-javadoc and xmlrpc-javadoc (part of java-devel group) Note that both Deployment_Guide and openoffice.org have updates, so if you don't care about kdelibs-apidocs, tetex-doc and *-javadoc, you can still use this image as a local base. * The updates as of 2007-04-26 from CentOS replace their originals: - autofs-5.0.1-0.rc2.43.0.2 - bind-9.3.3-8 - cups-1.2.4-11.5.1 - Deployment_Guide-(en-US and pt_BR)-5.0.0-21 - dhcp-3.0.5-5 - ekiga-2.0.2-7.0.2 - emacs-21.4-18.1 - evolution-data-server-1.8.0-15.0.2 - file-4.17-9 - firefox-1.5.0.10-2.el5 - freetype-2.2.1-17 - gcc-4.1.1-52.el5.2 - gnupg-1.4.5-13 - kernel-2.6.18-8.1.1 - krb5-1.5-23 - libwpd-0.8.7-3 - libX11-1.0.3-8.0.1 - libXfont-1.2.2-1.0.2 - module-init-tools-3.3-0.pre3.1.16.0.1 - net-snmp-5.3.1-14.0.1 - nss-3.11.5-3.el5 - php-5.1.6-11 - postgresql-8.1.8-1 - samba-3.0.23c-2.el5.2 - spamassassin-3.1.8-2 - squid-2.6.STABLE6-4 - thunderbird-1.5.0.10-1.el5 - tzdata-2007d-1 - virt-manager-0.2.6-7.0.2 - wireshark-0.99.5-1 - xen-3.0.3-25.0.3 - xorg-x11-apps-7.1-4.0.1 - xorg-x11-server-1.1.1-48.13.0.1 - yelp-2.16.0-14.0.1 * automatic detection on boot for i386 or x86_64 install - default label linux now calls com32 module l32or64 (attachment l32or64.c) that selects 32 or 64 bits kernel according to long_mode flag in cpuid - new boot targets linux32 and linux64 that force 32 bit or 64 kernel * single 32 bits initrd for i386 and x86_64 - new /init (attachment renmod.c), that symlinks /modules to the correct version - /modules.i386 with the original modules from the i386 initrd - /modules.x86_64 with the original modules from the x86_64, but with the paths in modules.cgz changed to $kver/i686/ instead of the original $kver/x86_64/, as the anaconda loader was looking there for the modules (it's probably ignoring the run-time arch and relying on the compile time one) - the space savings from using a single initrd aren't that much (1.5), so using the two separated initrds is still feasible (and l32or64 supports it), but the x86_64 initrd needs it's .buildstamp replaced with the one from i386. * single 32 bits minstage2 and stage2 - anaconda support for space separated list of available archs in .discinfo (attachment discinfo.patch) (anaconda has at least 4 different places where it parses the .discinfo file. something should be done about that!) - yum support for repodata.%arch location (attachment repodata.arch.patch): -> repodata.i386 and repodata.x86_64 (there was a supposed fallback to repodata if no repodata.%arch existed, but it didn't work in my tests, so you won't be able to use these stages with original repositories for network installs (ln -s repodata repodata.x86_64 or repodata.i386 should be enough, though)) - runtime replacing of usr/lib/rpm/macros with the correct one for the arch (attachment rpm_macros.patch) usr/lib/rpm/macros.i386 from i386/images/stage2/usr/lib/rpm/macros usr/lib/rpm/macros.x86_64 from x86_64/images/stage2/usr/lib/rpm/macros ln -fs /tmp/rpmmacros usr/lib/rpm/macros - symlinks for directories or files with i386/i686 in their name, with i386/i686 replaced with x86_64 (not sure if this was needed, but I didn't feel like making more tests): ln -s i686-redhat-linux-gnu etc/gtk-2.0/x86_64-redhat-linux-gnu ln -s i386-redhat-linux-gnu etc/pango/x86_64-redhat-linux-gnu ln -s keymaps-override-i386 usr/lib/anaconda-runtime/keymaps-override-x86_64 ln -s screenfont-i386.gz usr/lib/anaconda-runtime/screenfont-x86_64.gz ln -s i386-redhat usr/share/grub/x86_64-redhat To recreate the image with your own packages or comps.xml: 1. populate the CentOS rpm directory with the rpms of your choosing; 2. call createrepo in the iso root dir: createrepo -g path_to_comps.xml . 3. rename repodata to repodata.i386 or repodata.x86_64 and fix the relative paths in repodata.%arch/repomd.xml: perl -pi -e 's/repodata/repodata.i386/g' repodata.i386/repomd.xml 4. repeate for the other arch. 5. create the iso: mkisofs -o ../centos5_32and64.iso -b isolinux/isolinux.bin \ -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table \ -r -pad -J -joliet-long -V "CentOS" . 6. add checksum to iso: implantisomd5 ../centos5_32and64.iso 7. record it: growisofs -Z /dev/cdrom=../centos5_32and64.iso -- lfr 0/0

Installed CentOS 5 today, question about an error I'm getting
by Preston Crawford 01 May '07

01 May '07

So I did a fresh install today. Decided to go ahead and upgrade. Everything seems okay save for three problems. #1 - I get a message during boot saying that an Intel microcode update didn't work. Something about not being able to find /proc/microcode. #2 - I can't use the Firefox extension HTML Parser. Anyone use this. #3 - Off and on GDM crashes and I get dropped into a prompt. Any ideas?

FreeNX authenticates but no desktop on centos 5 ??
by Jeremy Gray 01 May '07

01 May '07

Hi all, I am new to CentOS and freeNX -- both look really awesome, a huge thanks to all the people making them happen. I am having a problem with freenx that appears to be specific to centos 5. my client authenticates but then no desktop comes up. however, when I connect to a similar machine running centos 4.4, I authenticate and the gnome desktop just pops up sweet as can be. I also have a vnc connection to my centos 5 workstation working, and can get a gnome desktop through vnc, and direct X11 connections are fine. the two nxserver machines have stable IP addresses, I have root access. the nxclient machine is a mac G4 PPC (which presumably makes no difference at all), with very recent download of the mac OS X client from nomachine. I followed the instructions for setting up freenx on centos 4.4 found here: http://linuxgazette.net/135/knaggs.html and it worked perfectly the first time I tried. the key steps were wget http://mirror.centos.org/centos/4/extras/i386/RPMS/nx-1.5.0-1.centos4.i386.… wget http://mirror.centos.org/centos/4/extras/i386/RPMS/freenx-0.5.0-10.c4.noarc… sudo rpm -Uvh nx-1.5.0-1.centos4.i386.rpm sudo rpm -Uvh freenx-0.5.0-10.c4.noarch.rpm plus a quick copy-paste of the client dsa key, and nxserver --adduser <me> For CentOS 5, I tried the yum-based instructions found at http://wiki.centos.org/FreeNX (which says that freenx only works with centos 4, and the bottom of page says "FreeNX (last edited 2007-02-08 23:38:36 by JohnnyHughes )" -- hopefully its just the wiki is out of date) I also tried adapting the above steps to use the centos 5 packages from http://mirror.centos.org/centos/5/extras/i386/RPMS/ freenx-0.5.0-13.el5.centos.i386.rpm 08-Apr-2007 11:00 66K nx-2.1.0-6.el5.centos.i386.rpm 08-Apr-2007 11:00 2.9M either way, I get authenticated but no desktop comes up in the X11 window on the client machine. (just to be explicit: using exactly the same client I do get a desktop on the centos 4.4 machine). While trying to connect, During this time, on the remote (CentOS) machine, its clear that something is happening, because "ps -ef | grep nx" on the server machine gives me root 5627 3378 0 10:38 ? 00:00:00 sshd: nx [priv] nx 5629 5627 0 10:38 ? 00:00:00 sshd: nx@notty nx 5630 5629 0 10:38 ? 00:00:00 /bin/bash /usr/bin/nxserver -c /usr/bin/nxserver nx 5771 5630 0 10:38 ? 00:00:00 sleep 60 jg 5800 5393 0 10:38 pts/1 00:00:00 grep nx I checked out a couple other things on the web on how to set it up and these did not help (they were very helpful, just not with my problem about the desktop not coming up). E.g., http://fedoranews.org/contributors/rick_stout/freenx/ I also noted other posts about freenx on this list, but they did not seem to be relevant However, I note that at http://wiki.centos.org/FreeNX is says that freenx only works with centos 4, which I am hoping is simply out of date, as freenx is shipped as part of centos 5. I saw a post today saying that freenx is supposed to work exactly the same on CentOS 5 as per instructions for 4. hmmm. I've tried uninstalling freenx on the centOS 5 machine and reinstalling. any suggestions appreciated! many thanks, --Jeremy

I basically followed the instructions posted in http://linux.web.psi.ch/livecd/usbdisk.html and use the CentOS Live CD iso. I used a 2G Lexar FireFly (1G partition formatted via FAT for the LiveCD and 1G /home via ext3). If I need to transfer files, I will copy them to the FAT partition. I hope this helps! Mark

I was able to make a live USB pendrive (Lexar FireFly) with the CentOS 4 Live CD, which I use as my primary OS, and plan on doing the same when the 5 Live CD is available. Mark

Slow performance
by Ashley M. Kirchner 01 May '07

01 May '07

Hi folks. I'm posting this to both the Fedora as well as the CentOS lists in hopes that somewhere, someone can help me figure out what's going on. I have a dual Xeon 3GHz server that's performing rather slow when it comes to disk activities. The machine is configured with a single 160 GiB OS drive (with CentOS 5.0) and 4x500 GiB drives setup in a RAID-5 configuration. All drives are setup for 3.0 GiB SATA link, and the motherboard also supports that. Looking in dmesg when the system comes up, I see that reflected as well: ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1.00: ATA-7, max UDMA/133, 312581808 sectors: LBA48 NCQ (depth 0/32) ata1.00: configured for UDMA/133 scsi1 : ahci ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata2.00: ATA-7, max UDMA/133, 976773168 sectors: LBA48 NCQ (depth 0/32) ata2.00: configured for UDMA/133 scsi2 : ahci ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata3.00: ATA-7, max UDMA/133, 976773168 sectors: LBA48 NCQ (depth 0/32) ata3.00: configured for UDMA/133 scsi3 : ahci ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata4.00: ATA-7, max UDMA/133, 976773168 sectors: LBA48 NCQ (depth 0/32) ata4.00: configured for UDMA/133 scsi4 : ahci ata5: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata5.00: ATA-7, max UDMA/133, 976773168 sectors: LBA48 NCQ (depth 0/32) ata5.00: configured for UDMA/133 scsi5 : ahci Now, I don't know what performance numbers *should* be, but on a 1.8 GiB copy on the RAID (cp from one location to another on the RAID), it gets done in just under 50 seconds. If I try to delete the folder afterwards (rm -rf FOLDER) it takes a few seconds to do so, however if I delete the CONTENTS of the folder, it does so within a fraction of a second (but then 'sync' takes a few seconds to catch up.) That same folder that I'm copying contains 452 jpeg files in it, ranging from 2.5 to 6.2 MiB. Doing some image processing on them is where it takes a long time. At the moment I'm doing a simple thumbnail creation with the ImageMagick suite (convert FILE -thumbnail "200x200>' `basename FILE .jpg`.th.jpg) and it takes upwards of 8 minutes to complete. The whole time it's running, 'top' reports the server load as follows: load average: 1.06, 1.00, 0.81 And the CPU usage is around 9%. Interestingly, if I run the same command and have it create .png instead, it takes longer, but I won't go there just yet. My question is, is this the expected performance on something like this, or should I be able to get better results? Is there something I should or could do to speed up disk based processes? Or is this something where it's more memory intensive and I need to look at adding more (right now it has 2 GiB of memory.) This problem is causing one of our web sites to time out because it's trying to process hundreds of image files and generate thumbnails, and it's taking forever to do that. So I'm starting at the bottom of the pile here, hardware. If it turns out the hardware is fine, and there's nothing else that can be done to speed it up, then I'll move forward to other possible culprits, such as the routines within the site scripts themselves... -- W | It's not a bug - it's an undocumented feature. +-------------------------------------------------------------------- Ashley M.
