booting CentOS in rescrue mode from USB (+over network)
by Martin Minka 14 Aug '07

14 Aug '07

Hello, is there a way to boot CentOS 4.5 from USB flash key in rescue mode ? The prefered solution would be to have booting part of CentOS started by SysLinux and download the content of CD1 from a network server (HTTP), like Anaconda is able to use command "method". Best regards, Martin

I know that you know what you are talking about, but, I don't know what to modify the Subject to, at this time. After reading the Wiki page Akemi referred to, I tried this on the box with the problem and on my box, where it works perfectly: [mailing-lists@dell2400 ~]$ gnome-volume-manager [mailing-lists@dell2400 ~]$ gnome-mount gnome-mount 0.5 The results were identical on both boxes.

So, it *is* something with automount and not a problem in GNOME. I looked at the /etc/sysconfig/autofs in that box and everything is commented out, like on my box. I will be studying the above web page!

I have one other idea: I have only tried this with GNOME. Both boxes also have KDE installed. I want to try it with KDE, to verify that it is an automount problem and *not* a GNOME problem. Lanny

The default value is 1 (true), and allows for compatibility with the Sun automounter options specification syntax.

decTOP - Centos install fails but DSL frugal install worked
by Robert Moskowitz 13 Aug '07

13 Aug '07

I got 4 of those decTOPs (http://www.dataevolution.com/dectop%20info%202.htm) and upgraded the memory to 512Mb. I cannot get Centos 5.0 to install. I have the keyboard mouse attached to an ATEN USB-PS/2 adapter (probably should try without this). I have a USB DVD/CDRW drive. The install CD boots just fine. But then the install says, "No CD" and takes me to Askmethods. So I use FTP, as I typically do anyway. They have a generic USB ethernet dongle, but the last device listed on the ethernet devices seems to work just fine. I get all the way through configuring and when it gets to Resolving Dependencies, it crashes. Something about not finding the kernel? And how do I remotely write the debug information? FTP does not seem to be the protocol used. So I partitioned a drive on another system. In partition 4 I copied the 6 ISO CD images. I boot from CD, and then switch to Local Harddrive from /dev/hda4 and /. . Then install follows the same behaviour as the FTP install, so at least I know it is not the USB ethernet. And there is no option to write the dump to /dev/hda4 Openfiler 2.0 hangs at "Resolving Dependenies". Just sits there. Oh, Openfiler 'figured out' to load up a USB driver to get to the CD. I haven't found my FreeNAS CD to see what it does. But the latest D*#nSmallLinux (DSL) had no trouble booting and running of CD. Now I have successfully done the Frugal install to the hard drive and am booted without the CD at all. Now I REALLY want to run Centos on a couple of these units. What should I look for that is causing Centos to fail to instal? How do I capture that debug trace? Since I DO have DSL up and running, if there is some test to perform, let me know. I haved NO experience with DSL or Knoppix. Next is an ASTLinux install on one of the boxes. I really want Trixbox instead.....

NAS -- Centos 5 DIY or Openfiler 2.0
by Robert Moskowitz 13 Aug '07

13 Aug '07

I need to set up a NAS. Got a box with a 200Gb drive ready to go. I have installed Openfiler 2.0 on it but..... I really can't add other services, like FreeRadius (keep the list simple for now). So maybe I should just stay with what I know and use Centos. Other experiences? Are there good DIY NAS instructions for Centos 5?

Before I added that line to the /etc/fstab file in my daughters box, I did a "yum update autofs". No joy. Then, I added that line to the /etc/fstab file. No joy. Possibly, if I do some more research, I can figure out what to change your suggested line to. However, in my box, there is nothing like that in the /etc/fstab file and automount works perfectly. I would like to know what is putting this line into the /etc/mtab file in my box, when I have the CentOS DVD in the drive: /dev/hdc /media/CentOS_5.0_Final iso9660 ro,noexec,nosuid,nodev,uid=503 0 0 Whatever is causing that line to be added to /etc/mtab apparently makes the automount work properly.
