Though, one needs to understand how the mandriva control panel works behind the scenes and where it is configured to use device-mapper and why. QUESTION #2 - I booted twice (before and after making the above change) and compared dmesg. I found that before making the change, there were many lines of device-mapper errors and these were gone after making the change. So what were these error messages? device-mapper: 4.6.0-ioctl (2006-02-17) initialised: [EMAIL PROTECTED] device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table lines repeated about 50 times device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table In respect of which physical device does this error occurred? Can you tell? QUESTION #3 - While GOOGLing for this, I found some mentions of EVMS. I seem to remember that on a previous version of Mandriva I had disk-access problems until I un-installed EVMS. But now, I see that it's installed on my system. Do I need it and if so, why? AFAIK, EVMS stands for Enterprise Volume Management System. It is some opensource project targeted at providing the sysadmin a consolidated way to manage all the storage devices he has no matter what technology is used to administer them. (LVM / MD / etc.) I played around with this tool once, and as far as I recall, it takes advantage of device-mapper in the process, though I can't remember how. QUESTION #4 - I still don't know the answers to the questions I asked in my previous post.

For instance: - what are these dependencies? If I did my math correctly then: 8 - This is the major number of the SCSI kernel driver. 32 - Is the minor number pointing on /dev/sdc 'ls -l /dev/sdc' should show you these numbers. - how did they get created? Well. Ask Mandriva :) But it proves that you have devices managed by device-mapper. - why only for sdc (not sda or sdb)? same answer here. In the bottom line, disabling device-mapper in some kernel hack did the trick. Just be aware that if you run 'depmod -a' it will not sustain. (Same goes for a kernel upgrade). Best way is to understand where it is configured that your sdc devices should be managed by device-mapper. (recursive grep on /etc is a good start). Device mapper gives you the flexibility to manage your devices in an easier way. It is modular and robust (bla bla). It can be used to encrypt your devices, have LVM over them, and many other neat features. Anyhow, I don't think that any of this robust features are speaking to you, because you chose to partition all your disks into very small parts in a very hardcoded way. - Noam

VMWare and native Windows XP
Good day. I have dual-boot computer with Linux on one partition (sda1) and WinXP on the other (sda2). Linux has VMware installed. (VMware-server-1.0.2-39867) Now, I want boot into Linux, and from VMware run windows, installed in the sda2. VMware-server allows specify whole disk or partition to be disk for virtual machine. I specify it. And try to but VM. To my surprise I got grub boot loader, select windows, and windows began to boot and the fail. Windows was installed on (native) SATA drive, and VMware make Windows think drive is LSI, which was not installed in the first place. In linux adding modules mptbase.ko mptscsih.ko mptspi.ko to the initrd can solve the problem. Is it a way to achive same on Windows, i.e boot windows, which was installed native under VMWare ?

Recommendation for a Laptop
Hi all! I'm looking to buy a laptop. It should be able to run any of WinXP Professional, Win2003 Professional (both with some optional drivers, all included), Mandriva 2007.1 (out of the box) and Debian Testing (possibly with some tweaking). Since I'll be running Windows on VMware or booting from MSWin, I don't mind paying the MS tax. I don't want Vista pre-installed, though (!) - only WinXP or Win2003. What I need: 1. FOSS 3-D drivers. 2. FOSS Ethernet drivers. 3. Working screen. 4. Working external projector/screen connector. 5. Big hard disk - at least 80 GB. 6. At least 2 GB of RAM. 7. I don't mind buying a separate USB wifi connector with FOSS drivers (but possibly non-FOSS firmware). 8. A well-known company. (Lenovo, Dell, HP, etc.) 9. Good experience with it. 10. All hardware works with open source drivers, at least on Linux. FreeBSD would be a big plus.

Re: Recommendation for a Laptop
I'm using a Dell Inspiron 6400 lappy with Fedora Core 6. At the time I bought it, one HAD to purchase Windowx XP with it, but now I think that you have a choice of Vista or some Linux distro, I don't know which. I don't think that any lappy today comes without Vista. What I need: 1. FOSS 3-D drivers. I've never tried 3D, but for everyday use the Radeon x1400 card in this Dell works just fine. 2. FOSS Ethernet drivers. Wireless and wired internet work fine. Did take some tweaking, though, and I cannot promised that I used only open source drivers (but I think so). 3. Working screen. At it's native 1400x1050 resolution. 4. Working external projector/screen connector. Check. 5. Big hard disk - at least 80 GB. That's what I've got, at 7200 RPM. Could have gone even bigger. 6. At least 2 GB of RAM. Check. 7. I don't mind buying a separate USB wifi connector with FOSS drivers (but possibly non-FOSS firmware). Built in. 8. A well-known company. (Lenovo, Dell, HP, etc.) It is a Dell. 9. Good experience with it. I'm happy so far. The thing scratches just by looking at it, and the rubber feet fell off in less than a month. Other than that, I'm rather happy. 10. All hardware works with open source drivers, at least on Linux. FreeBSD would be a big plus. I haven't had a chance to test the bluetooth, and the wifi/video card may need closed source drivers. I don't understand why you are so uptight about using open source drivers when you plan on dualbooting with Windows. Should I remind you that windows is not open source?

I had a short conversation with Alex Pinchev of Red Hat last week and he told me that Dell choose Ubuntu as the distro to be preinstalled from factory at some their laptops. I don´t know if these laptops will also provided with some Windows version or proprietary drivers, but they would work well with any other major distro without tricky solutions for drivers.

Re: Performance monitoring for selected process
Hi, From your mail I cannot understand the context of your problem. Are you looking for profiling tools to improve programs developed by you or a user that wants to understand why a process is slow?

Re: Performance monitoring for selected process
Maybe it's too trivial, but try to check the CPU Time on the moments of slowliness, so you can tell: - If the process' CPU Time progressing faster in moments of slowliness (High cpu load) - If there's hardly any progress in CPU Time (process is waiting for IO or some other resource) Also I tried to see what /proc/pid/stats give, nothing amazing but maybe it helps.
