5.5 ISO size vs RHEL
by Anthony Caetano 20 May '10

20 May '10

Hi We use CentOS and RHEL, the 5.5 RHEL ISO for x86_64 is 3.7GB (**), the CentOS one is 4602MB (***) split over two DVDs. Is this reasonable and correct? Any ideas why would there be such a discrepancy if they are built from the same (or very similar) source? Regards Anthony Caetano ** the md5sum checks out, and RHN lists the size as 3,532 MB *** CentOS-5.5-x86_64-bin-DVD-1of2.iso + CentOS-5.5-x86_64-bin-DVD-2of2.iso (according to ftp.heanet.ie:/pub/centos/5.5/isos/x86_64 )

I'll try that tomorrow. *sigh* Well, I did that, and then went through a song-and-dance uninstalling the stuff the nvidia installer had put in, and uninstalling this so that would succeed, and then *really* getting rid of the stuff it wouldn't, and then using yum again. And it still got trash. My user's sure he had not turned it off, that he just came in one morning and it had lost it, and I have every reason to believe him (he *does* know what he's doing). So, at this point, we've given up - his machine wasn't on a UPS, and given the power in this building, there's a high probability of a surge, and something on the card got fried - so he's got another machine, and we're probably going to call this one dead. Thanks, though, for the el repo link. I've got to remember that one. mark

Problems after update to 5.5
by Colin Coles 20 May '10

20 May '10

Hi, I have updated 8 machines so far and 2 are refusing to boot on 2.6.18-194.3.1.el5 kernel, they just hang at: 'Starting udev:' but when I revert to 2.6.18-164.15.1.el5 kernel they boot fine. Any pointers? Cheers, Colin.

[Solved] Yum segmentation fault when updating to CentOS v5.5

Something is not right with this particular >machine and I think it's for the best to do a complete reinstall anyway. Seems like a bad ram-stick, and insufficient cooling of the same, might have had something to do with the inconsistent errors I kept getting. I added four new ram-sticks and so far the problems have not come back. Thanks all for the help when trouble-shooting! -- /Sorin

How to create a printer that prints directly to a file?
by Bryan Berry 20 May '10

20 May '10

I am trying to learn how to share printers using samba. I am doing most of my experiments at home w/ libvirt and where there are no printers. How can I set up a printer device that just prints to a file on my system? That would really help me in my experiments.

Networking setup/help
by tdukes＠sc.rr.com 20 May '10

20 May '10

I had to install 5.5 from scratch and now I have to rebuild my home networking system. I haven't had to mess with this stuff in over 5+ years and I'm sure there may be better ways of doing it now. My liunx box acts as firewall/gateway for 2 other pcs. I was using a script from the Linux IP Masquerade HOWTO with ddclient (since I have a dynamic ip). Also, I don't think I need a full name server. Can I get by with a caching nameserver? Thanks!! Eddie

A Directory/Subdirectories Disappeared - which log file to look for this kind of information?
by Wang, Mary Y 19 May '10

19 May '10

Hi, A directory/subdirectories just disappeared on our dev box, and we don't know what happened. Is there a log file that logs this kind of stuff (such as who/date did a 'rmdir'). The /var/log directory has a lot of files and I'm not sure where to start. Thanks in advance. Mary

Generic RAID question
by James Bensley 19 May '10

19 May '10

Does anyone know if using unequal drives in a RAID 0 is possible? I was looking to set up a software stripe but if I have two volumes of unequal size I wish to stripe over, will the OS try and work around this by say only using as much space as is available on the smallest drive or is there anyway it will use all of both drives? Does it have to be a perfect block/byte balance across drives? (I'm assuming yes?) -- Regards, James. http://www.jamesbensley.co.cc/

trying to rebuild an old nvidia driver
by m.roth＠5-cent.us 19 May '10

19 May '10

Let me start by saying that no, I can't get a new card for my user. So, I've got the 96 nvidia driver. I've rebuilt it several times before, and Nvidia's installer's always worked fine. Actually, I have the 73 on my system, and just updated to 5.5, and no problem. HOWEVER, I last rebuilt my user's driver back in mid-April, after the last kernel update (was that mid-March?), and everything was fine... until the other day, when he walked in to tell me he'd had to reboot, and it wasn't working, and dropped him to command line. I rebuilt it... and it dies. As in, sometimes, I have to go to another machine and ssh in to reboot, and sometimes, I have to power cycle his system. I get garbage with the nvidia driver; with nv, I can at least get one of his two monitors working. When I try x with the nvidia driver, it just keeps printing out initializing GART, I think it is (I've lost the log), and then that it has failed to allocate ROP. Anyone see anything like this? I've unpacked the executable, and started working with the makefiles (and yes, I do understand makefiles), but see things like a lot of warning in the compile, and the one that makes me nervous is make CC=cc KBUILD_OUTPUT=/lib/modules/2.6.18-194.3.1.el5/build KBUILD_VERBOS E=1 -C /lib/modules/2.6.18-194.3.1.el5/source SUBDIRS=/scratch/NVIDIA-Linux- x86-96.43.13-pkg1/usr/src/nv modules make -C /lib/modules/2.6.18-194.3.1.el5/build \ KBUILD_SRC=/usr/src/kernels/2.6.18-194.3.1.el5-i686 \ KBUILD_EXTMOD="/scratch/NVIDIA-Linux-x86-96.43.13-pkg1/usr/src/nv" -f /usr/ src/kernels/2.6.18-194.3.1.el5-i686/Makefile modules test -e include/linux/autoconf.h -a -e include/config/auto.conf || ( \ echo; \ echo " ERROR: Kernel configuration is invalid."; \ echo " include/linux/autoconf.h or include/config/auto.conf are mis sing."; \ echo " Run 'make oldconfig && make prepare' on kernel src to fix it ."; \ echo; \ /bin/false) Even though both those files exist and are where they should be. I've googled, and find no references to those, and really hope it's not the card going bad.... So, any clues? mark

CentOS 5.5 - VMware Fencing in Cluster
by James 19 May '10

19 May '10

I'm trying to use the newly integrated fence_vmware script within luci. I add it as a shared device and assume it is setup right (it is added as a device but it doesn't seem to do any connection test). When I try and add my shared fencing device as the primary device to a node it says it is updating the node configuration but then doesn't actually add the fence in the node's configuration within luci. If I try and fence the device it predictably fails to fence the device. I tried using fence_vmware from the command line (which seem to have some trivial errors which keep it from even running) and it works fine (after I fixed fence_vmware). Can anyone offer me advice on setting up the shared fence and applying it to nodes for VMware Fencing?
