CentOS 5 :: Buffer I / O Error On Device HDD - Logical Block 176935

Sep 4, 2009

I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error:
Memory for crash kernel (0x0 to 0x0) not within permissible range
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00)
The failed "read 10" packet command was:
Buffer I/O error on device hdd, logical block 176935

(This error message repeats for another 9 or 10 times then it says the following)
Red Hat nash version 5.1.19.6 starting
Setting up new root fs
(Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).

Setting Clock
Starting udev
Loading default keymap (us)
Setting hostname local host.localdomain
Setting up logical volume management
Checking file systems

These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.

General :: Cannot Mount Hard Disk: Block Count Exceeds Size Of Device

May 11, 2011

I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. Last night I did a clean install of Ubuntu 10.10 on my primary hard disk (call her HDB) and from there proceeded to upgrade directly to Ubuntu 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive. When mounting from file browser:

Code:

Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda,missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so The end of dmesg said the following:

Code:

dmesg | tail
[ 82.130904] EXT4-fs (sda): bad geometry: block count 122096646 exceeds size of device (122096381 blocks)

my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:

Code:

# sudo e2fsck /dev/sda
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 122096646 blocks
The physical size of the device is 122096381 blocks

[code]....

this is as far as I've gotten. This drive holds over a decade's worth of work for me and is extremely valuable. I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. What is it that I need to do to restore my drive to working status?

Hardware :: Buffer I/O Error Device Hdc Logical Block 15

I am trying to debug the issue of a desktop that has for the last two weeks started having kernel panics at boot time. This machine has been running flawlessly for the last 8 years, and has had three OS upgrades. I am using memtest to try to understand the issue.

Fedora :: Kernel: Buffer I/O Error On Device Dm-0, Logical Block 124

Nov 28, 2009

I have 2 hdds, with encrypted / and /home. Besides there are four other (encrypted ext4) partitions I use rarely. In Fedora 11 at boottime I gave the luks passphrase for / and home and the system booted as intended.

Whenever I needed those extra encrypted partitions I mounted them in Nautilus. Now, in Fedora 12 at boottime dracut tries to open all the encrypted partitions, / and /home are mounted fine, but opening all the other partitions gave the following messages in messages.log:

Quote:

dracut: luksOpen /dev/sdb6 luks-02a0e706-a26f-4019-a2a0-88a0366a994d
kernel: Buffer I/O error on device dm-0, logical block 124

kernel: Buffer I/O error on device dm-0, logical block 124
kernel: Buffer I/O error on device dm-0, logical block 124

[code]....

...and these messages are repeated with the other partiitions, and the boot time takes very, very long. How can I tell dracut to ignore those extra encrypted partitions at boottime?

Ubuntu Installation :: No Such Device Error Message?

Mar 17, 2010

I have been using my desktop as a dual boot machine for several months now. The primary hard drive with windows on it died, and since we have been using ubunto 9.10 exclusively, I just removed the dead drive, changed the jumpers on the secondary drive to primary and did a clean install on the drive which presumably formats the disk before installing. When I try to boot from the hard drive i get the following message:

General :: Kernel Panic - Not Syncing: VFS : Unable To Mount Roof Fs On Unknown-block Error?

Apr 21, 2010

I downloaded the ubuntu-9.10-desktop-i386.iso file from the website, extracted it, and ran the Wbiu.exe file - it prompted to get my info and then restart. Upon restarting, I then had the choice to run Windows or Ubuntu, and I've been running Ubuntu ever since.

I ran into some speed-bumps. Upon entering the Ubuntu option at my start-up prompt, I go to another prompt asking me to choose from: Ubuntu, linux 2.6.31-20 Generic Ubuntu, linux 2.6.31.20 Recovery mode Ubuntu, linux 2.6.31-14 Generic Ubuntu, linux 2.6.31-14 Recovery mode Windows 7 installer Windows Vista installer
I've been choosing the very first one, the 31-20 generic, but just this morning after downloading some programs from the Synaptic and transferring a few Gbs of music, I received this error prompt: Code: [2.879604] Kernel panic -- not syncing: VFS : Unable to mount roof fs on unknown--block (8,2) After that, I've been running the 2.6.31-14 generic installer. I have no idea what any of this means and I've spent time crawling through threads trying to figure it out. I mean, it still WORKS but I just help but think I've done something very wrong. ALERT: SUDO PASSWORD QUESTION

I hope the cautionary sign above has dispelled any annoyed gurus who have answered this question dozens of times before. I've crawled through my fair share of threads concerning this, the best corollary being the following: forum/linux-newbie/157773-solved-sudo-password-errors-usb-internet-issues.html; which, strangely enough, was never really solved. Like the user in that thread, when I access the terminal and type in a command, the next line invariably states "[sudo] password for jacob' -- when I hit enter and type in the long list of possibilities I've read (read: sudo, su, su root, su passwd, sudo passwd, sudo root, et al.), alas, nothing happens but the same statement.

Slackware :: Compiling Large Slackbuilds - Error-message - Not Enough Space Left On Device

Aug 20, 2010

I am currently running slackware 12.2 on a 25 GB partition. I like to use slackbuilds, but when I try to compile larger tarballs (like abiword, or a patched version of Ghostscript as I did today) I receive an error-message: 'Not enough space left on device'. I think the size of the partition must be big enough (I never got this message when compiling with Linux From Scratch). I think it has something to do with the size of my /tmp directory, but I don't know how to fix this. Is there a way to solve the problem, so that I could be able to use slackbuild-scripts?

OpenSUSE Network :: Mount Command Gets Stuck With No Error Message?

Jun 25, 2011

I am using 11.3 on one machine and 11.2 on the other (a netbook). 11.4 won't install on either and 11.3 on the netbook fails to install as well.

I am using the same setup as I have always used when both systems ran 11.2 (details below) but now I can only mount a drive in one direction. In the other direction the mount command gets stuck with no error message until it eventually times out. I can ping and ssh the machines from each other without difficulty.

Even in the direction in which the mount apparently works (11.2 mounting a drive on the 11.3 machine) when I try to copy files across nothing actually happens.

exportfs -a was run successfully on the exporting machine, and nfsserver is running on both machines as does nfs client.

The exporting machine is 192.168.1.102 (eeelinux) and the other machine is 192.168.1.101 (nina).

Details:
The /etc/exports file on the exporting machine (192.168.1.102) looks like this:
eeelinux:/home/naima # more /etc/exports
# See the exports(5) manpage for a description of the syntax of this file.
# This file contains a list of all directories that are to be exported to
# other computers via NFS (Network File System).

Ubuntu Networking :: Samba Share : Get An Error Message "unable To Mount Location, Failed To Mount Windows Share"?

2. //media/SG1500GB/Music. I set this up for everyone full access and I can see it at all my Windows machines but,I can't get into the folder. Windows keeps giving me an error stating network path not found.I also try to access it via the Nautilus (Places/Network/system/music) and get an error message "unable to mount location, Failed to mount windows share".

Fedora :: Getting Error Message - Can't Hit On Secret Mount Syntax - Make At Least To 1400x1050?

Nov 26, 2010

I am not ready to upgrade my Fedora 13 to 14 yet, but I wanted to test some things in 14. So, using the live CD, I installed Fedora 14 under Virtualbox. But some things are not working and the Virtualbox Help files aren't helping. I have added my Fedora 13 /home/jjj/ folder as a shared folder with the name Home_jjj. The instructions say that in Fedora 14 I must mount it with "mount -t vboxsf share mount_point." So (as root in Fedora 14). I used the command "mount -t ext3 vboxsf Home_jjj /media" but I got an error message. I tried varying the command different ways, but haven't hit on the secret mount syntax. I would really just like to add it to Fedora 14's fstab file to make it auto-mount. I have an external monitor, which Fedora 13 sees, but Fedora 14 cannot see it. The main display for Fedora 13 is 1680x1050. Fedora 14 installed itself with 1024x768 as the max. I tried changing it with xrandr -s, but the only resolutions xrandr will take are 1024x788, 800x600 and 640x480. How can I make it at least, say, 1400x1050?

CentOS 5 :: Installing CentOS 5.5 On An Old PC -- Query On An Error Message?

Oct 24, 2010

I'm trying to install CentOS 5.5 on an old Pentium 4 desktop PC I have, which is not being used for much other than being a MTA, and I want to migrate this functionality onto the CentOS platform for stability (Windows is a perpetual nightmare. I partitioned a spare 20GB to experiment with, and I want to install CentOS into here to play around with first so I can move my files around between Windows and CentOS, until I'm happy all of the stuff is gone, then I can scrub the Windows partition and claim the space for CentOS.

So, I've downloaded and burned the DVD and tried to install. I start the install with no args from the main install menu, and the process goes through some probing and then comes up with the "Welcome to CentOS" menu. I go through this, and then it tries to start X Server. It fails, and falls back to text mode. I get the "Welcome to CentOS" screen again, and then proceed through it. I set my keyboard layout to UK, then this message comes up at the bottom of the screen:

"_X11TransSocketINETConnect() can't get address for localhost:6001: Temporary failure in name resolution"

then on the next line: "Cannot open display :1" If I force the install to text, by typing "linux text" at the first menu, I get about the same way through, but the install just hangs doing nothing, and no disc access to the install disc.

CentOS 5 :: Mount Error: Can't Mount An Encrypted Volume With An Overlaying Ext3 FS

Jun 6, 2010

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.
