I want to convert all my NTFS partitions to ext3 since I'm no longer running Windows, at least on my main machine at home. I'm planning to tar the NTFS partitions to an existing ext3, reformat the partition as ext3 and untar it back. What is the best way to accomplish step two of this - reformatting the partition? I've only done this so far during the installation phase, and that

I notice that the OO that comes with CentOS 4.4 is version 1.1.5, which is fairly ancient. Are there any plans to update this for OO 2.2, or 2.1, or 2.0? Or is this a RH thing exclusively? In which case is CentOS Plus likely to get a more recent version? OO 2.0 is way better.... Mark Hull-Richter Linux Kernel Engineer (949) 680-3082 - Office (949) 680-3001 - Fax (949)

1) Is this the right place for kernel internals questions and if not, what is? (Refresher: I am relatively new to Linux kernel internals, but not kernels in general. I've work on Unix and proprietary kernels, including my first seven years as a professional developing a whole system from the ground up.) 2) I noticed this morning that my GLMatrix screensaver is not working any

I know this is a little off topic (not as usual, dammit!), but I figure at least one of y'all can handle this one. I have tried to configure my CentOS4.4 Plus desktop for samba sharing with the VMWare Windows that runs on it. However, no matter what I've done so far, I can't get the Windows to recognize this machine as a legitimate network destination. Here's my samba

This might be a gnome problem, but.... I've noticed that, on occasion (frequently), when I try to look at or modify my display configuration, the Applications->System Settings->Display doesn't come up. It asks for the root password, which I give it, and then nothing. I ran system-config-display form the command line, but it dies thus: [root at mhullrichter mhr]#

As long as I'm still awake, I tried to install CentOS 5 (earlier) from a DVD I downloaded via bittorrent about a week or so ago. It boots fine, but once it starts to load the kernel (in graphics mode), it gets to the point where it announces the four i/o schedulers and then stops dead. No disk activity, no DVD activity, nada. Is there a known problem here and if so what, or is this a new

I rebooted my machine this morning and now instead of running normally, my GLMatrix screen saver flashes as it repaints the screen, more and more noticeably as the screen fills up with glyphs. I didn't change ANYTHING and this was not happening before the boot. Anyone have any ideas why this might be? Thanks. Mark Hull-Richter, Linux Kernel Engineer DATAllegro (www.datallegro.com) 85

I went to enable samba on my home machine, which has a largely plain vanilla install of CentOS 4.4 Plus, and the smbd and nmbd files are missing. As you may know, this makes it rather difficult to run samba. For some reason, the winbindd binary is present, and rpm reports: samba-common-3.0.10-1.4E.11 samba-client-3.0.10-1.4E.11 as present. So how do I retrieve the missing samba binaries/ Do

I installed the kernel-2.6.18-8.el5.src.rpm today and went to build it, but it fails with this error: $ rpmbuild -bp --target=`uname -m` kernel-2.6.spec Building target platforms: x86_64 Building for target x86_64 error: Failed build dependencies: unifdef is needed by kernel-2.6.18-8.el5.x86_64 I double checked and this appears to be the latest kernel source rpm on centos/5.0/os/SRPMS.

I'd like to point out that overall I am quite pleased with CentOS 5, although I am having more fun with it than I did with 4.4 and I knew less about CentOS then (duh). Most things seem to work fine, including a relatively smooth installation from the DVD image I downloaded, although the number of screensavers I can see (and this could be related to the ATI/dual head problem) is pathetically

I had to reboot my work machine today, and it came up in text mode (!). I did an init 5, but that had no effect (wrong command?). I killed the three gdm processes, and voila, X server mode. Where do I look to find out what is not right here?

I could swear that this was working just last week, but now when I run the Adobe Acrobat reader, it hangs. If I run it "directly" (/usr/bin/acroread) with -DEBUG as the first argument, I get an infinite loop of: expr: syntax error I tried removing and reinstalling it, but no change. Any ideas? -- Mark Hull-Richter DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso

1) I'm actually not building a custom kernel per se, just one from the standard 2.6.11.4 with our configuration. I may be adding a custom driver, but unless I can get the standard kernel to boot,... 2) I have been told that after 2.6.11.4, support for the Infiniband driver is dropped, and we need that. If this is not the case, I would be delighted to know that and proceed accordingly.

Has anyone with an nvidia video card had issues with CentOS 5 so far? I've been holding off on installing 5 at home because of the trouble I've been having with my video here at work, but here I have that lovely ATI card and there I have a geFORCE 7100gs and am, so far, successfully using the nvidia driver with CentOS 4.4 without significant problems. Just wondering.... -- Mark

I have been following the wiki on how to build a custom kernel, and it works great. Except, I am doing ongoing work with the internals of the kernel, and it is really awkward to set up a change and then build it using the standard methodology (edit the file to change, diff it against the original to make a patch file, rebuild the whole thing). Isn't there a way (and what is it) to play

I decided to go ahead and remove totem (don't much care for it anyway), and when I double-click a sound file in nautilus, it runs mplayer to play the file, but I also get an error window (from mplayer) that says "[AO OSS] audio_setup: Can't open audio device /dev/dsp: Device or resource busy" but it is playing the sound file just fine. I can close the error window and everything

Are there any good packages (or just places to look) to observe and track kernel behavior (other than to add such and build a custom kernel)? I'm doing some performance analysis on different types of i/os on different file systems, and I need far more sophisticated information than iostat or vmstat produce. Any useful suggestions would be appreciated. Thanks. -- Mark Hull-Richter
