General :: Error: VFS: Cannot Open Root Device "343" Or 03:43
Jul 16, 2010
I have been working with a project pc. I have a new HD loaded with Linspire. After loading the o/s I replaced the motherboard and cpu. I now have a Biostar A780L (Didn't see it listed on the HCL) and an AMD Athalon II Multi-Core Processor. Now when the pc boots I get an error:VFS: Cannot open root device "343" or 03:43 append a correct "root" boot option Kernel panic: VFS: Unable to mount the root fs on 03:43 I tried reloading the o/s but the disk won't read from the DVD ROM. Checked my BIOS and it appears to me that it should read from the DVD ROM first but it goes to the HD and tries to load the o/s there.

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:
[Code]....
I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

Installed Maverick last night... the system has been working fine all day... then on a reboot tonight got the following.
RAMDISK: gzip image found at block 0
usb 1-2: new high speed usb device using ehci_hcd and address 2
uncompression error
VFS: Cannot open root device "mapper/mylaptop-root" or unknown-block(0,0)
[code]....
Then it gives the Kernel Panic
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper not tainted 2.6.35-22-generic #35-Ubuntu
Then a call trace...This is a brand new install of Maverick I copied my files onto a USB and did a fresh install on the whole drive using the alternate CD (the desktop and netbook editions both failed to read on my system) was previously using Karmic with no issues. I tried to e2fsck the dev/sda1 from the CD in "repair broken system" mode but the return was "clean" I read that as the file system being intact but this is an area that I have no real knowledge in.

I have added CentOS5.5 x86-64 to a linux box that already contains installations of Ubuntu 9 and SL 5.2. Grub2 was installed with Ubuntu and is on the MBR of the disk. I did not install grub with anaconda/Cent. Grub update in ubuntu finds the Cent install and addes it to the grub.conf, and Cent appears in the grub menu at boot. If I select Cent, I get the following error.
VFS: Cannot open root device "sda7" or unknown-block(0,0)
Please append a correct "root=" boot option
Below is the output of boot_info_script, which gives the relevant boot file data. There are still grub conf files on the SL install, but grub is not installed there anymore.
Boot Info Script 0.55 dated February 15th, 2010
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #6 for /boot/grub .....
sda3/boot/grub/grub.conf:
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that all kernel and initrd paths are relative to /, eg.
# root (hd1,2)
# kernel /boot/vmlinuz-version ro root=/dev/sdb3
# initrd /boot/initrd-version.img

When booting up my IBM Thinkpad Ubuntu stalls giving the following messages:
Cannot open root device "uuid=58a5831c-5757-49f8.....
Kernal Panic - not syncing: Unable to mount root fs on unknown-block
Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.
I am or was using Hardy.
It seems to me that the program is telling me it can't find the hard drive or the partition where the OS resides. I have my drive partitioned with into sections for booting, the OS and my Home directory.

I have been trialling Slack 13.1 on a spare 32b system for a couple of weeks, and today I took the plunge and put it on my main machine. I completely re-partitioned the drive (using the Slack disk) and installed Windows7 on one partition and Slack 13.1 on another. The install worked fine and I tested that it boots from LILO into both Windows and Slack perfectly. I then ran:
slackpkg update
slackpkg install-new
slackpkg upgrade-all
And since then it fails to boot with the following:
Code:
VFS: Cannot open root device "802" or unknown block(8,2)
Please append a correct "root=" boot option; here are the available partitions:
0840 488386584 sde driver: sd
0841 97659103 sde1
0842 19535040 sde2
0843 498015 sde3
[Code]....
I have seen many, many similar problems when searching Google but they all seem to be caused by different things.

I am using a kernel with no initrd. I have had this kind of panic before. Usually it means that the kernel can access the hard drive because the driver for the controller or filesystem isn't built into the kernel.
The kernel is 2.6.34 vanilla.
My IDE controller is a Silicon Integrated Systems SiS 5513, and I built the driver for it into the kernel BLK_DEV_SIS5513=y
My /boot (hda1) is ext2, and everything else is ext3
EXT2_FS=y
EXT3_FS=y
My grub entry (hda2 is my root partition) kernel (hd0,0)/vmlinuz root=/dev/hda2

I needed to use CIFS for accessing a NTFS network share. I decided to include CIFS in the kernel and tried compiling and installing it. Now when I (try to) boot in my new kernel with CIFS support, I get the message: gave up looking for root device.

An old machine in our office, running Ubuntu 6.06 all of a sudden will not boot up. I get the following info during boot:
Uncompressing Linux... Ok Booting the kernel
mount: Mounting /root/sda1 /root failed: No such device
mount: Mounting /root/dev on /dev/.static/dev failed: No such file or directory
[code]....
I haven't changed anything on the system as far as I'm aware, and I ran some HD diagnostics and everything seems fine. however when I try to mount the drive with the following command:
sudo mount -t ext3 -o rw /dev/hda1 /mnt
I get the following error:
mount: wrong fs type, bad option, bad
superblock on /dev/sda1, missing code
page or helper program, or other error
In some cases useful info is found in
syslog - try dmesg | tail or so
I ran fdisk -l and it says the partition type is Linux. The output after running dmesg | tail :
[12207.483801] init_special_inode: bogus i_mode (101)
[12207.483809] EXT2-fs: corrupt root inode, run e2fsck
[12260.427078] init_special_inode: bogus i_mode (101)
[code]...
Update: After running e2fsck -p /dev/sda1, I get the following info:
/dev/sda1: clean, 142449 / 9584640 files, 5402711 / 19161520 blocks

I have been trying to update my server from 6.06 server to 10.04 server. My attempts have been complicated by versions later than 6.06 not being able to properly read my CD-ROM. I used the 'do-release-upgrade' mechanism to upgrade to from 6.06 to 8.04 and then to 10.04. 8.04 loaded OK, but 10.04 fails to boot with the surprisingly common "Gave up waiting for root device" error. It stops at the built-in shell prompt. If I exit from the shell, it seems to boot up normally.
I have verified that the boot partition is /dev/sda1 and the UUID for the partition is correct. My system is an older IBM eServer xSeries 350 with quad 700MHz XEON processors and a 36GB SCSI drive. This system properly installed from the 6.06 CD and boots under this version without problems. So I have some questions. Only the first one needs an answer.
1. What do I need to do to get my system to boot properly?
2. Why was this software released with this error?
3. Why wasn't the faulty loader pulled from the release until it was fixed?
4. Is it possible to revert to the 6.06 loader, which works fine?
5. Why doesn't the loader attempt to try something else that should work instead of just giving up?

VFS: unable to mount root FS on unkown-block(202,17)
I have a Dell xps with a dual core, 8 gigs ram, a primary hard drive with vista on it, and a secondary with linux in its future. It starts loading vmlinuz but ends up with the kernel panic before anything else. I am able to install earlier cores (5-8) and vista recognizes the ram just fine.

Currently running rc2. Downloaded 11.2 final DVD, md5sum is good, burned DVD, YaST says media check is good. (And for completeness burned a second DVD and get the same problem.)
On booting from the DVD I select "Installation" - a kernel loads and starts checking available h/w devices then crashes with the above message.
Followed by Please append a correct "root=" boot option.
Tried with root=sda1 (partition that is /) and only change is unknown-block (0,0)
My best guess is that I have EXT4 (did a clean install of RC2)? And/or I dont have a swap partition?

Hello,
this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.
Error in console:
libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied. libusb requires write access to USB device nodes.
my sript runs:
scanimage
--device $MODEL
--resolution=$RESOLUTION
-x 5104 -y 6840
my groups:
uid=1000(fogie) gid=100(users) groups=100(users),7(lp),11(floppy),12(mail),15(man),17(audio),18(video),19(cdrom),20(games),21(sloca te),83(plugdev),84(power),86(netdev),93(scanner)
Even a simple:
scanimage -Lv
in console gives this on a separate --current pc as well.

The system is an old AMD Duron 650MHz that was dug out of the garbage, trying to set it up as a light duty server. I installed ubuntu 10.04 with no errors or troubles during the install, however whenever the system is booted it sits at a cursor for about a minute then goes into busybox giving the error "Gave up waiting on root device." and says that the hard drive does not excist. If I sit at busybox for about another minute and type exit it then boots ubuntu 10.04 with no errors or issues.

I want to be able to change the root device, say from sda to sdb, so that I am able to remove sda. I don't believe this is possible with chroot, as I am changing the root folder to a mount point that exists on sda (sdb is not on fstab), so removing it would lock up the system.
Any thoughts how I can do this?

So my question is why should we restrict device ownership to root? And what does device ownership mean anyway in Linux?

I am trying to install Ubuntu 10.10 from a USB flash memory stick. It works fine until around 95%, where I get the following warning/error:
[Code]....
I click OK and the installer seems to finish nicely, except the terminal throws several errors along these lines (see photo):
[Code]....
I tried also with 10.04 LTS, the difference being that the install warning appears two or three times instead of once. Some results from googling (Ubuntu Forums, Ubiquity bug) suggest unchecking the initial update options. I am going to try this but I'm not sure if I'll be able to get the boot loader right (there seemed to be problems with this).
