I have been using CentOS 5. for around 3 months. It was all fine and was having a pleasant experience using CentOS. Today when i turned on my computer and booted CentOS i am having the below error: Grub comes up, allows me to select CentOS 5.4 kernel image. and displays RedHat Nash version: and then the below error occurs:
[Code]....
When I rebooted my system (RHEL 5.3 x86_64), I got the following error when it was booting up:
Code:

So to try and fix this, I booted from the OS disk and did a linux rescue.
Here's some of the results of the commands I did:
Code:
Here's a screenshot of the output from fsck after it's done, notice it says 0 bad blocks but the system was modified:fsck results
I then reboot but now I get the errors:
Code:
Full screenshot of the startup errors I get now here: current bootup error
Does anyone have any ideas on how I can fix this? Was the fsck I did initially the correct thing to do to fix that initial group descriptor error or did I make things worse?
I'm having issues with getting my USB ports to work on my server. USB keyboards, mice, drives, flash drives, card readers, etc. will not work on this server.

I tried to get 3d hardware support in my FC12 install. I grabbed the latest appropriate drivers from the nvidia website for my Geforce 6800 XT graphics card. I changed the inittab file to boot to command line, ran the .run file as root and ran into a couple errors doing so.
I then proceeded to use yum (which i do like but this is a bad scenario for me thus far) to update my drivers to the suggested kmod-nvidia drivers that exist out there. Once all of the installation was completed I rebooted and got the following error displayed at the top of my screen after the fedora loading bubble disappeared. The system just seems to hand at this point....
"usb 2-1: device descriptor read/64, error -62"
I did a hard boot on the machine and tried again, this time i pressed the esc key to watch the interactive startup screen and noticed that after "enabling local filesysem quotas: [ OK ]" i get a
***Warning -- SELinux targeted policy relabel is required.
*** Relabeling could take a very long time, depending on file
*** system size and speed of hard drives.
This will continue with asterisks across the screen until eventually it stops and then I am stuck as to what to do from here on out. What could possibly be causing all of this mayhem?I have tried to use the fedora core 12 install cd to launch it into "rescue mode" and from the bash command line proceed with modifying my grub.conf to not use the "newly installed kernel (2.6.32.11-99.fc12.i686)" that was installed with yum during my kmod-nvidia driver installation.
I'm designing an embedded USB device. When I connect the device to the computer, I get the following messages:
usb 1-3: device descriptor read/64, error 2

usb 1-3: device descriptor read/8, error -71
usb 1-3: device descriptor read/8, error -71
usb 1-3: device descriptor read/8, error -71
Note that other USB devices work fine. I am fairly certain that the problem is with my hardware. I'd like info on what these error messages mean to help my debug. Searching Google I wasn't able to find any explanations about what these errors mean exactly.

I've been tasked with fixing a Red Hat system that dies with a kernel panic during the boot stage:
Code:
EXT3-fserror (dev sda1): ext3_check_descriptors: Inode bitmap for group 4 not in group (block 67239937)!
EXT3-fs: group descriptors corrupted!
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument
I can boot into a Rescue CD, but I'm a bit out of my element because I don't use EXT3 myself, and I've never had to repair a corrupted file system before.
I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
I got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.

I am using Wind River Linux- 2.6.27.18-WR3.0bg_standard. The problem is whenever I execute "reboot, ls, cd" and many other commands the OS prompts me an error-
"end request: i/o error, dev sda, sector "(different sector each time)" and
EXT3-fs error (device sda1):ext3_get_inode_loc:unable to read inode block- inode-4088001, block-4097027
I also executed "dmesg", it also showed similar errors. Has the disk gone bad or the kernel is corrupted?
I have a recent install of ubuntu 10.10 on a brand new rig, and everything appears to be working properly but I get these 2 errors during bootup that seem to make the book process take a bit longer than expected but haven't actually noticed a problem in performance.

[6.752860] hub 3-2:1.0: config failed, can't read hub descriptor (err -22)
I have been unable to find a site with information on what err -22 means. From what little I have found on the issue it seems to be something with the usb 3.0 hubs on the back of my motherboard?

I got this error message when installing Fedora 11 by an installlation DVD (download from [URL]) Unable to read group information from repositories. This is a problem with the generation of your install tree. This error message appeared after the step that the installer asked me to choose where to install boot loader and configure the GRUB boot menu. The error message came with two button: [Retry] and [Exit installer].

I am trying to dual boot Vista and F10 and I have 2 different 400GB hard drives to do it on. On the first HD, I have Vista installed but when I try to install F10 on the second, I get this error message:
Quote: Error: Unable to read group information from repositories. this is a problem with the generation of your install tree. I've looked it up and found some forums but none answer how to "fix" it (if it is indeed something that you fix).
I'm doing a Kickstart install of Fedora 11 with a DVD ISO as the installation source and the ks.cfg file in the root folder of the DVD. The error message I get is: "Unable to read group information from repositories. This is a problem with the generation of your install tree."

This problem is most likely caused by a mismatch between /etc/passwd and /etc/shadow or /etc/group and /etc/gshadow. The program will exit now.
Some research showed that I need to use vipw and vigr respectively to find an inconsistency between these two sets, which I did - to make it easy I copied each from [vipw | vigr] to an excel file and did =exact(%1, %2). There are no inconsistencies.

i have an external harddrive, hooked up by usb. /dev/sdb it came as a fat drive (sdb1). when i realized, i had copied 250 gb to it already. so, i made a new ext3 (sdb2) partition, copied the data from the fat to ext3, and then deleted the fat drive and moved the ext3 it with gparted. it mounted fine after it was moved, but after i tried to resize it, which didn't work, it will not mount.

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

I have an FC13 x86_64 server and having trouble building RPMs, but I don't think it's specifically an RPM problem. I think it's a tty management or other type of problem.
When spec files have a "%files -f filelist.txt", which contains the list of files for the RPM, it calls the /usr/lib/check-files script, which sorts the files that are supposed to be in the RPM and compares them with the files that are in the built RPM before they are packaged.
The trouble is that the sort fails.
Here's the trace from the check-files script:
The above doesn't show that the output from sort is redirected into those /tmp files. The first sort succeeds because it reads data sent by the "find" in the same shell. The second sort fails because (I think) it cannot read data from stdin for some reason.
What could possibly cause this? I've checked various permissions, libraries, even used strace extensively, all of which is inconclusive.
This is one of my test server boxes, so this problem is something that I've caused, but I have no idea what.
libc controls input and output, correct? Could it somehow be a glibc problem, or a devpts problem? I can run a simple command and pipe it to sort with no problem. It appears to only be related to sub-shells.
I also replaced sort with cat and just tried to redirect stdin in that file to a temporary file, and that also fails.
I've tried running it with selinux disabled and that has no effect.
Mount of filesystem failed. A maintenance shell will now be started CONTROL-D will terminate this shell and retry. groups: cannot find name for group ID 0 root@Sergioc-desktop:"#

View 5 Replies View RelatedI have a netbook with Ubuntu 10.10 installed in it,and a Pc with also ubuntu 10.10 in it , but x86_64.
I want to copy some iso files and data from my user home directory on the netbook , to the user home directory of the other pc , using a 8 GB usb formated in ext3 with gparted in my pc.
One iso is a windows 7 one to burn then with K3b , as i need to have windows installed in that box. Also of another iso that i have to burn too (windows 7 recovery disk) , and 3 anti-virus trials for windows.
As the usb is owned by the root (or more properly the mounting point,no?), and i can't use my user to copy data to it i usually do :
Usually , what i use is "sudo nautilus" then go to the place where is the data , copy it , and paste it then in the usb. Then in the other pc i do a chgrp and chown to the iso or file.
But , perhaps this is not the better approach. I have investigated a bit , and i think that i have found a better way , but i have some dudes.
The method is change the owner,group and permissions of the mounting point:
Code:
cd /media
ls
umount /dev/sdb1
sudo mkdir usb
[Code].....
If i do this steps in both computers, with each user,in the netbook i can copy the iso to the usb (as fox can write to the mount point of the usb ), but can the other user in the pc 'mulder' read the iso , so be copied to /home/mulder, and then be able to burn it in k3b with success ?
I suppose that having 766 , it should be able to read it , but would have the own of the file ?
How important is not to only be able to read it , but also own it ?
I suppose if the user ID is the same , wouldn't be any problem ,as each ubuntu would supose that the file is owned by their user.
Perhaps the user name change,but if the ID is the same , the user is the same for ubuntu , not any different, no ?
I created a encrypted volume on top of software raid1. These are my steps:
1. Create logical partition on sda
2. Create logical partition on sdb (same size)
3. Change type to partition to 'fd' for both partitions
4. Check that the both partitions are same size and type fdisk -l /dev/sda && fdisk -l /dev/sdb
5. partprobe
6. Make sure there are no remains from previous RAID installations on /dev/sdb by running: mdadm --zero-superblock /dev/sda6 mdadm --zero-superblock /dev/sdb6
7. mdadm --create /dev/md4 --level=1 --raid-disks=2 /dev/sda6 /dev/sdb6
8. watch cat /proc/mdstat
9. update mdadm.conf mdadm --examine --scan | grep mdx >> /etc/mdadm.conf
10. Load twofish module [root@localhost ~]# modprobe twofish
11. # cryptsetup -y -c twofish-cbc-essiv:sha256 create ftdata /dev/md4 Enter passphrase: Verify passphrase:
12. mkfs.ext3 -b 4096 -R stride=8 /dev/mapper/ftdata
13. mkdir /ftdata
14. Mount the encrypted volume:
mount -O noatime /dev/mapper/ftdata /ftdata
It mounts successfully this first time. When I cd /ftdata, I can see the lost+found dir
[Code]....
So why is it that I can't mount my encrypted volume after the first time? I am giving the correct password when it asks to.
So I upgraded my hard drive and went with a clean Lucid install. But now I want to get files off my old drive. When I re-hooked it back up (now 2 drives in the system), ubuntu refuses to boot. It kind of boots then just hangs. Never gets to the desktop, and the HD lite on my case is constantly flickering (what could it be doing??)
I have it set up correctly in my BIOS so that the new drive is the boot drive, not the old one. The only difference is that the new drive is sata and the old drive is old school pata (ide). I even tried pulling out the old pata drive and hooking it up to a USB adapter I have. Looking at it in the Disk Manager, it shows it as unformatted, and old faithful GParted doesn't even see it!
Now get this: I pulled out my new sata and put back in the old ide drive and guess what, now it wont boot! Grub (probably MBR) is screwed up also! Any ideas how I can read the data from that old drive? Ether by getting my new lucid install to boot with the old drive as a slave in the system, or by hooking it up externally using USB?
I have a dual boot system and am trying to be able to access all partitions in both OSs. I've tried some windows software that are supposed to be able to read linux partitions, but without luck. Essentially, my linux OS (rhel) is represented as an LVM partition (within the logical volume is ext3). In windows (7), file viewing programs see the partition as "raw". Is there any software that can read LVM in windows?
View 1 Replies View RelatedI compiled a kernel using a previous kernel config after I switched to the ext4 file system. Previously it was using ext3 and the kernel compiled and ran fine. I added support for ext4 to the config but when I went to boot I had a kernel panic. The error was "kernel can't mount vfs on (8,5)". Root is on sda5, I don't know what the 8 is. I started over, using mrproper and made a new config, but got the same error. I created an initrd with the ext4 file system but then the kernel said it couldn't mount root on ext3 because of unique options. (something along those lines) I booted back into the default kernel and saw that it had a similar error right after the bios check, but it loaded fine. I'm wondering why the kernel is saying that the ext4 file system is ext3.
