Ubuntu :: Mounting None On /dev Failed: No Such Device?
Jan 31, 2011
I'm running Lucid with the 2.6.32-28-generic and 2.6.31-11-rt(abogani's ppa) kernels, on a fairly new laptop.When I boot the rt-kernel, right after grub I get a message:Code:mount: mounting none on /dev failed: no such deviceW: devtmpfs not available, falling back to tmpfs for /devThen after a few seconds, I see a lot of fast moving text and then Ubuntu starts just fine.when booting the generic kernel, I don't see any text at all, but it uses just as long time as the rt-kernel, so I guess the problem affects both.

I'm trying to install ubuntu 9.10, downloaded the iso from the site and burned it on a CD, but when I boot from my cdroom drive and choose install ubuntu option I get an ubuntu grey logo for a couple seconds and the I get this error:
I tried downloading a new copy and burning a new CD but still have the same error, no matter what option I choose when booting the CD.
Does anyone now whats the problem? What I'd like to do is install linux as the only OS (formating everything else) not dual boot or anything, I'm new to linux so it'd help if you guys could give me details on how to fix it
I have installed previous versions of ubuntu on this same computer but using the wizard inside windows.

I posted a similar problem sometime last week...but a little has changed(mainly I can access my files now): I recently performed the auto upgrade to Ubuntu 10.04 and upon restart of my machine I am presented with 3 screens. The first is a simple "GRUB loading". The second is "mount: mounting none on /dev failed: no such device". The third screen is a series of initializations, i.e. /dev/sda1:
clean, (number of files), (number of blocks)
*setting preliminary keymap...
and so on until it hits the line:
*checking battery status
at which point it will cease loading until i press the power button. The next thing that occurs is it kills all the processes it just initialized and shuts down the computer. I read that this is likely a problem from loading the wrong kernel and I can get into my files (using a boot 9.10 boot key). The problem is I don't know what files to change in order to get my system booting the right kernel.

The error message I keep getting during mounting is:-
device-mapper: remove ioctl failed: Device or resource busy
This is from ane external USB HDD I use as a backup device. I've tried formatting it as ext4 ane encrypting it from the command line
# mkfs.ext4 /dev/sdc1
# cryptestup luksFormat /dev/sdc1
which run without errors but an attempt to mount throws up the above error as well as saying - you must specify the file type (tried that) - and fails to mount. I've tried using YaST to format and encrypt it which throws up the same error when I run mount but actually does actually mount the filesystem Googling around has brought up info saying that it's probably a race condition brought on by invalid udev rules. I've got a (mostly) working system and the udev rules documentation leaves more confused than when I started.

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've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.
Hardware is a Sager 8887 (P4, 3.06HT, 60GB HDD, Radeon 9000 graphics adapter)

I have installed live cd on usb pendrive. Everything works great. How can I find out which device driver it is using? Where are the device driver files stored? How do you specify the device driver when mounting a device?

I've read hundreds of threads on this problem but they seem to be intermittent and the resolution has been using a different kernel version.
I'm using the latest kernel but I still have this problem
Running Logical Volume Manager gui and attempting to extend the volume results in the same error.

I use Ubuntu 9.04 I have a problem. I have a file, containing ext2 file system ( mke2fs -F ~/fs.ext2 )Is it possible to mount this file by user (not root) without editing fstab and from terminal?
P.S. Using /dev/loopN is not what I need. Maybe, it's possible to use FUSE, is it?

Having some troubles mounting my DVD-RW after a reinstall of ubuntu. Now using 10.10.
Code:
root@Johnsky:/# wodim --devices
wodim: Overview of accessible drives (1 found) :
-------------------------------------------------------------------------
0 dev='/dev/scd0'rwrw-- : 'HL-DT-ST' 'DVDRAM GH20NS10'
-------------------------------------------------------------------------
So there's my scd0 sitting pretty.
Trying to mount it.
Code:
root@Johnsky:/# mount -a /dev/scd0 /media/cdrom0
mount: /dev/sr0: unknown device
root@Johnsky:/#
sr0?
Code:
root@Johnsky:/# ls -l /dev/
total 0 .....
Lets try mounting sr0 directly instead.
Code:
root@Johnsky:/# mount -a /dev/sr0 /media/cdrom0
mount: /dev/sr0: unknown device
sr0 is still an unknown device.
I'm thinking when I reinstalled Ubuntu, it made some screwy links between devices. But I have no idea how to resolve this... and there's no point in my mind to adding the DVD-RW to /etc/fstab until I can actually mount it manually to know it mounts successfully. Back when I installed Ubuntu 9.x on this machine, I never had any of these issues. It picked up the DVD-RW automatically, appended it to fstab during installation, and done. But 10.10 seems to be having some troubles my 9.x installation didn't.

I've googled this issue ad nauseum but alas my poor PC is still quiet as a church mouse.I was prompted to upgrade to 10.04 and, despite knowing better by now (I seem to file a severe bug report following each upgrade), I chose to allow the upgrade to move forward due to a driver problem I thought might be fixed in the new version.The upgrade took over 9 hours but did complete and I rebooted afterwards. I never got my PC back, it's stuck during bootup on "mounting none on /dev failed".
Be cautious with advice. There is no menu.lst any more, this is Grub2.I have booted off of the Live CD and run the grub-install and mkconfig. I have edited grub to try different menu options by default. Each time, grub builds with 2 different kernels listed, neither of which are correct.

I recently noticed a bug with ndiswrapper in Ubuntu 10.4 which would prevent the mounting of new USB device classes. This bug has been noticed somewhere else, in particular in at least one older Ubuntu version, but has been carried over. This doesn't seem to be widely discussed, or the solution worked anecdotally, but the problem is actually more general in nature. At the moment I found a workaround that always works, but I don't have a permanent fix.
The problem kicks in only after ndiswrapper module is loaded into the kernel. Devices of the same USB *types* that were recognized *before* ndiswrapper is loaded will continue to work. For example, an USB memory stick will be mounted fine if an USB hard disk had already been used at some point before ndiswrapper was loaded. However, if one plugs in any other new type of device, for example, an USB mouse, after ndiswrapper is loaded, the new USB device will not be mounted. The workaround solution is to disable ndiswrapper before introducing a new type of USB device by doing:sudo modprobe -r ndiswrapper
Then, plug in the USB device. After it is successfully mounted, do: sudo modprobe ndiswrapper
The corollary is that if ndiswrapper is loaded into the kernel upon boot-up, only USB devices which were present at the boot stage will be recognized. But performing the above kludge will allow new devices to be recognized.It'd be nice if someone can come up with a more elegant fix.

let's say this system has 3 hard drives. Drive #1 and #2 are RAID 0 and Windows7 lives there. It is a hardware RAID, not software.
On Drive #3 Ubuntu has been installed using WUBI - it boots up and works okay - but it does not see the RAID array.
Do I just need a linux driver to be able to see & mount my "Windows" RAID0 array? Or is this even possible? Can anyone point me in the right direction?

So I am using a debian 5.0.4 version of Linux with a command-line interface (the bash shell).I have been trying to get my usb device to be readable, which I suppose means I need to run a mount command like mount -t usbfs /dev/usb /media/usb But I have not had any luck getting to access my usb drive...I run lsusb and find that it is attached, I can find it in the /proc directory, but I cannot access my usb drive

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.

I placed Ubuntu on the same drive as my windows XP is, and there were no problems, everything was fine, all drivers were working...I need to use kernel 2.6.29 and i read about "how to install a new kernel" on this forum. I downloaded 3 files, I installed them in a good sequence. After reboot I can choose between 3 kernels, and if I choose this, then there is a mounting problem:
mounting none on /dev failed
Afterthat there is written something else, what I cant read. Some seconds later ubuntu boots, but my (non-USB) mouse isnt working.

I recently had one of my computers motherboard die and so I moved the hard drive to another linux machine so I could access the data. The hard drive is installed correctly and I've mounted several logical volumes on the drive ok, but I'm having trouble with the two volumes which were encrypted. The LVM Gui in Fedora is ignorant to any encrypted LVMs so I looked around to see if others have solved this problem and found the following command:
# cryptsetup luksOpen /dev/vg_delldesk/lv_home luks-fedora
My Logical volume container is vg_delldesk and the encrypted volume is lv_home - when I execute this command I get the following error:
Device /dev/vg_delldesk/lv_home is not a valid LUKS device.
I have access to the root partition from the old box so the config files are there to reference the old setup if needed. My current box is Fedora 14 x_64, I have dm_crypt mod installed in the kernel as well.

I have written a script to take backup of my database in remote server which is a windows machine.i have mounted that machine to my server using the script and daily script will run automatically, i have scheduled it using crontab like that and backup will be taken. but if my remote server is down means it gets unmounted and my backup falls on my local linux server itself. i want a script to check whether the remote server is mounted or not if mounted take the backup or else stop the backup.

I have a 1TB external HDD which I use to store my music library of roughly 40 gigs. Therefore I would normally import music directly from it to my Rhythmbox library while keeping everything stored on the removable drive. In recent versions of Rhythmbox this is no longer needed as the application integrates my external HDD into the side pane and lists the music automatically. This is great although when closing Rhythmbox and reopening it, the drive has to be scanned all over again. This is a huge pain when it has to scan through 40+ gigs of music.
Therefore I would like this feature disabled and removed from my side pane. It is not needed and causes quite a large annoyance. Either I want it removed or the ability to keep the index of music from the drive in Rhyrhmbox at all times. Achieving this would be fantastic and would switch me back to Rhythmbox. recently I have been using Exaile which I love but rhythmbox not working bugs me.

I am currently using opensuse 11.2 with kde 4.3.1. I am having a problem when I connect my samsung R450. It will not mount or show up as a usable device in either Dolphin, Amarok, or on the device notifier. I have tried manually mounting but I get an error saying it cannot find such device. I did not have any issues using it in 11.1 with KDE 4.2. It is being recognized by my system, but not allowing it to show up as a storage device or being mounted.
output of dmesg:
PHP Code:
output of lsusb:
PHP Code:
When I shut of the usb mass storage on the samsung R450 it switches to modem and is properly detected and usable as modem by my system.I don't have any other problems with other usb devices, such as a digital camera or flash drives, so I don't know if I just missing a system setting or configuring something wrong.

I'm trying to use the most-base install of opensuse 11.4 and so i'm using the text-only interface. I looked up some guides on using the 'mount' command but I'm encountering problems. I tried doing.
mkdir /tmp/flash
su
mount /dev/sdb /tmp/flash
but first off, I don't even know if sdb is my flash device, there's ~60 things in my /dev/ directory, and ~10 things that look like 'sdb' but I try anyway, and I generally get an error telling me that either /dev/sdb is busy, or /tmp/flash is busy but I wanted to check here and clarify first, how do I even know which /dev/ item is my flash drive? When I plug in my flash drive, no less than 3 new entries appear in /dev/ so, I'm a little confused. What do I do?

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.

I am trying to install Debian in an old laptop. Of course, in this laptop there is windows installed and I want to respect it. My plan is to install Debian in a spare drive.Before installing Debian, I want to check what is inside each drive. In order to do that, I am trying to use the Debian installer CD. Then start an admin shell, mount the drives in read-only mode, and check their contents.
But when I run the command:
# mount -r -t ntfs /dev/sda3 /mnt/windows
I get the following response:
mount: mounting /dev/sda3 on /mnt/windows/ failed: No such device
