General :: Ubuntu 6.06: Mounting /root/sda1 /root Failed: No Such Device

Jan 22, 2010

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

General :: Mount USB Mounting /dev/sda1 On /mnt/usb Failed: Invalid Argument

I am using an embed linux application and trying to mount a USB device. The USB worked fine in windows. I then put it on my Linux box formatted (I hope correctly) And then tried to do the following to mount it

Code:

Disk /dev/sda: 4040 MB, 4040748544 bytes

General :: Dd Copy - Hard Drive Clone Fails When Mounting Root Androotblock - /newroot Failed

Oct 27, 2010

I am trying to replace an old, smaller, and dying laptop hard drive with a newer one, using a USB external drive. I first tried cloning disk to disk with Clonezilla, but it failed after cloning my root, swap, and /home directories it froze when it tried to reinstall grub. After 2x trying, I switched to dd, which I have never really used (I am fairly new to Linux in general). The actual command I used was:

Quote:

dd if=/dev/sda of=/dev/sdb bs=4096 conv=notrunc,noerror

All seemed ok and after approximately 2 hours my 80GB drive had been cloned onto my new 250GB, with dd giving what appeared to be a satisfactory closure summary. I tried to mount and access the drive from my external USB enclosure but could not view it, though the data is there, I believe, as the size and bytes show... The error that Dolphin is giving me is:

Quote:

error - wrong fstype, bad option, bad superblock on /dev/sdb1 Missing codepage or helper program or other error. When I installed the new drive directly into my laptop, it begins to boot (Sabayon 5.4, 2.6.35 kernel) but almost immediately I get (handwritten down, but this is close):

Quote:

detected real_root
mounting /dev/sda1 on /newroot failed: input/output error
!! Could not mount specified ROOT, try again
!! Could not find the root block device in .

[code]....

I am assuming that my issue has something to do with grub, and maybe specific UUIDs that don't match (?) but I'm not really certain. I have both Grub Legacy 0.9x and the newer Grub 2 installed (Sabayon is already moving over) but I still boot with Legacy, not with the new 2, as I don't know how to switch, and am not sure if I should yet. I thought that dd copied bit for bit, and I added the noerror´ just to try to get it all transferred, so I don't know what went wrong exactly, though something seems wrong with grub and the bootloader, I guess...

Ubuntu :: Mounting /dev On /root/dev Failed At Boot

Aug 21, 2010

I installed ubuntu 10.04 from the CD (downloaded from ubuntu website), all worked very well. until today that I decided to run the software updater. It installed all the updates correctly, I restarted ok, but i experienced a mini locks, for example when i was with firefox, firefox had mini hangs for about 15 seconds then run normally. Then all OS got unstable, windows showing no thing, for example when i tried to restart using the button, it didnot do anything. Well i reset my computer and BOOM!, im stuck after Grub showing me this:

mount : mounting /dev on /root/dev failed : No such file or directory
mount : mounting /sys on /root/sys failed : No such file or directory
mount : mounting /proc on /root/proc failed : No such file or directory

[code]....

I'm able to reproduce this. I installed a fresh 10.4 again, then installed propietary drivers (nvidia), restart, all working flawless here, then updating all packages using the update-manager, restart, here not all working well (same sympthoms) so i decided to restart, then BOOM AGAIN.. I did the process 3 times and, the same, so I think something is BROKEN. So im able to reproduce it but don't know what the hell is causing it.

Ubuntu :: Error - Mounting /dev On /root/dev Failed: No Such File Or Directory

Apr 4, 2010

I have recently experienced a problem that occurred after an automatic update. After the update it said restart system. So I did and proceeded as normal. when after the reboot Firefox suddenly stopped working, crashed and upon clicking it again only a blank box appeared. Then my other apps followed and i soon couldn't do anything so i shut down my computer. Upon restart I got a black screen with tons of text and something around the lines of

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory

[code]....

So I rebooted and pressed shift to open that grub thing and booted from an earlier kernel. This time it said checking HD for errors and after booted normally. Everything seemed fine but next day it did it again. Starting with Firefox crashing and then everything else. I again booted from a previous kernel and it worked but upon checking with uname -a it did not list the kernel i chose to boot from. So I decided to upgrade 10.04 to 10.10. This upgraded my kernel and deleted the old ones so i am hoping i am good now.

CentOS 5 :: Extra Root Filesystem Folders For Mounting Device

Oct 26, 2009

I was looking at the root filesystem folder for mounting a device when I noticed extra folders. I'm using an encrypted filesystem so I'm not sure if it's that, a break in or the default Red Hat layout. I searched these forums and Google to no avail on extra folders. The root system contains the following:

bin {fda00e13-8c62-4f63-9d19-d168115b11ca} media opt selinux usr
boot home misc proc srv var
dev lib mnt root sys

Ubuntu :: Unable To Boot The 10.10 - Mounting /dev On /root/dev Failed: No Such File Or Directory

Feb 9, 2011

After upgrading from 10.04 to 10.10 I have had some problems booting my Ubuntu. It all started when restarting after the upgrade, and I got the error;

Code:

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init= boot arg

BusyBox v1.13.3 (Ubuntu 1:1.13.3.1ubuntu11) built-in shell (ash)(initramfs) After searching the Internet, I found a "solution". I just had to boot with a USB stick with the Ubuntu Rescue Remix (the normal Ubuntu USB won't boot either), and i wrote;

Code:

sudo fsck /dev/sdb5

Now I could start my Ubuntu again. So whats the problem? If I turn off my computer the normal way, there is no problem, but if I log off, put it into sleep mode, if something happens and I have to turn it off with the button it goes back to the first problem, and I have to reboot it with the USB stick and fix it all over again! If I don't have the USB stick with me, I probably wont be able to use my laptop!

Ubuntu Installation :: Mount: Mounting /dev On /root/dev Failed: No Such File Or Directory

May 14, 2011

Doesn't seem to matter which version, every time I try to install Software raid on an Ubuntu server system, it blows up with this error. Seems I've had trouble for several versions.

Code:

mount: mounting /dev/disk/by-uuid/f35415ee-4c14-4eb1-995f-f19fbcd760c7 on /root
failed: Invalid argument
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory

[code]...

I've done it on Centos Fine, and followed the many different instructions I've seen for Ubuntu. The only luck I've had was with bios raid, but I would much rather let Mdadm handle things.

My build:

ubuntu-10.04.2-server-amd64 CD install
AMD 1055T 6Core
4GB ram
Asus M4A88TD-MUSB3

[code]...

I install both as letting Ubuntu decide partitions for one drive, do the same for the other, and create a raid, and do them from scratch. No dice, same problem. I've tried that one as logical and as primary too. No difference. Something just doesn't like booting from a raid 1 Mirror. I've tried installing grub on both HDDs (sda1 + sdb1)I've tried several CDs, burned from several machines. Re-downloaded from Torrent and from the website. The DVD drives work since I purchased new DVD drives for both one workstation and the server. Things install fine under CentOS, software raid comes up.

Slackware :: /dev/root Mounting & Booting Into The Generic Kernel Failed?

Jul 4, 2011

I just did a full install of Slackware64 on my netbook. Everything was sweet until I tried switching to the generic kernel. Even before this, I noticed when I ran the mount command it listed not sda3, which really is the root partition, but /dev/root as the root partition. This also appears in mtab, but not fstab. So yeah, here are the errors when I try booting into the generic kernel:

Code: mounting /dev/sda3 on /mnt failed: No such device No /sbin/init found on rootdev (or not mounted) bin/sh: cant access tty: job control turned off

I've tried rebuilding the mkinitrd_command_generator.sh script several times, as well as lilo.conf. But no success I've looked at some similar old threadss here but most of them are related to slackware 12 and older, so I don't know if these issues are related or not.

Slackware :: Lilo Multiboot And Initramfs - Mounting True Root Device

Apr 13, 2011

Recently I installed a Linux distro (Pardus) which boots using initramfs. I am completely novice here. In the former configuration I used lilo to boot OpenBSD, Debian and W2k (it is easy for me to configure lilo to boot OpenBSD). But initramfs is a something completely new for me. As I understand it is a virtual file system with a standard directory tree and the information stored on that system is used (to boot the kernel?) to mount the true (physical) root device. The first question is how to properly describe a system (kernel image) booted with initramfs in the lilo.conf.

Ubuntu :: Initramfs Boot Error - Mount: Mounting /dev /root/sys Failed: No Such File Or Directory

Feb 19, 2011

Okay, so on occasion when I boot into ubuntu I get this error

[mount: mounting /dev /root/dev failed: no such file or directory]
[mount: mounting /dev /root/sys failed: no such file or directory]
[mount: mounting /dev /root/proc failed: no such file or directory]

[code]...

I get the error when I open any of the kernel versions or any recovery mode. Ubuntu 10.10 Desktop is the only OS installed on the computer, which is a Lenovo S10-3. I can eventually get it to go away, sometimes by repeatedly unplugging it and plugging it back in, and sometimes I will boot into GParted, do nothing, then restart and it will work.I have found some solutions online, but all of them involve the error happening as a result of dual booting with Windows.I have made no major system changes recently, so I can't see anything like that being the problem.

Fedora Installation :: Install Ok - But Boot Failed - No Root Device Found

Install went ok, but after rebooting it says: "No root device found. Boot has failed, sleeping forever."

During install from the live CD I didn't "v" the boot (efi or something?) because I thought Grub would take care of everything.

Should I just reinstall again and choose the Fedora bootloader? Won't it mess up Grub?

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.

Ubuntu :: Long Disk-activity-pause On Boot - Between Mounting Root And Mounting Swap?

Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:

Why would there be a 15-second pause (during which the disk is slammed) between mounting root and mounting swap? During this time I see nothing but a blank purple screen, there are no cycling dots or text scroll. Is this normal and I'm just freaking out over nothing because there's no indicator of progress?

General :: Gnome/nautilus Mounting And Unmounting Without Root?

Feb 28, 2010

Gnome version 2.28.1 with kernel 2.6.31-14 on an Ubuntu 9.10 Karmic box.I'm wondering how usb drives, etc get automounted in gnome now days. Thought it might be fusermount, but no.Gnome-mount is not installed. Perhaps it is via AL or udev, but what commands control it? I've found posts that talk about using gnome-mount, but these are outdated as this package isn't even installed by default anymore.I would like to unmount certain volumes via the command line, but without having root privileges as gnome is doing by clicking in nautilus. I would like to do the equivalent from the command line.

Are there any command lines commands that will allow me to do this (not talking about pmount which is not installed)?Also, is there a way to prevent automounting of just certain devices, but not all? I have a USB with 7 different things on it (a "built-in" CD for some reason for windoz users, the original NTFS, and 5 linux partitions). I really only want one of the linux partitions (an XFS for DVD isos) to automount but not all the others. I would like not to have to disable ALL automounting as in:
Code:

$ gconftool-2 -s /apps/nautilus/preferences/media_automount --type=bool false
$ gconftool-2 -s /apps/nautilus/preferences/media_automount_open --type=bool false

General :: How To Change Root Device

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?

General :: Redhat 5.3 Mount Failed Without Root?

May 16, 2011

In Redhat 4.x, we can use 'smbmount' to mount another linux samba server with 'user1'. But now we used redhat 5.3(64bit), there is no smbmount and I can only user mount command via root.

How can I mount a folder via 'user1', not root?

(BTW, I can run '#mount hostname:/sharename /mnt/u1, but the access right of /mnt/u1 is only for root.)

$ls -la
drwxrwxr-x root:root 4096 May 18 2010 u1

I wish it is "user1:user1"
drwxrwxr-x user1:user1 4096 May 18 2010 u1

I also edit /etc/fstab and add the following in. hostname:/sharename /mnt/u1 noauto,user1 0 0

mount: only root can mount xxx on xxx. It still doesn't work.
