Ubuntu :: Hung Up Restarting After An Update - Running Fsck Off Live CD
Dec 23, 2010
My computer got hung up restarting after an update yesterday so I switched it off and back on, which led to the error message "No init found. Try passing init= bootrag", looking that up I found a thread that recommended running fsck to fix the errors.
I first went to disk utility and did the check filesystem and repair button but that just had a pop-up that said "File system is NOT clean." So I went and tried fsck on the drive which gave me the error message "fsck.ext4: Device or resource busy while trying to open /dev/sda1 Filesystem mounted or opened exclusively by another program?"
Figuring this may have been caused by the disk utility I restarted and tried fsck again without opening any other program, and I still get the same error message. What is causing this? Swap? What can I do to get fsck running to fix the original problem?

I am attempting to get beyond my grub> as it has hung up there after trying to update my Samsung netbook from 10.04 to 10.10. I have found some answers but a basic question is where do I load grub from a livecd to the mount point where I have already installed my Ubuntu I have attached a screen shot of my partitions on my 160 gb hd and hope it can be opened?

my root partition was corrupted after loss of power, so now my gentoo system won't boot. I need a Live CD that can fsck it back up, but ubuntu never boots on my machine.

Well, I noticed this by accident while trying to use dash for the rc.d scripts. I messed up and forgot to link it to /bin, and as such, the system failed to boot properly and would not respond. I rebooted (forcefully), but this messed up the filesystem. I booted the sw64 install DVD and tried to mount it, and it would not mount.
I tried to run fsck on it, but it said that fsck.jfs in NOT available. Eventually I booted my old slamd64 12.1 DVD and it had fsck.jfs. Any reason why this rather useful program was removed ? Or is it a bug, or is my DVD messed up? I guess I should just keep around another live CD, I do keep knoppix, but it boots so slow and I don't understand it at all, it's so hard to do anything with it.

I have been using Ubuntu for a couple of years, and I had some problems that nobody could fix, so I thought I would try Fedora.
If I want to automatically fix errors in Fedora (or Ubuntu) on the next boot the normal method is to type [code] sudo touch /forcefsck at a terminal prompt. In Ubuntu after I boot it up I can see on my computer screen that fsck is running, but with Fedora there is no indication on the screen that fsck is running.
Since I can't see it, how do I know that Fedora is actually running fsck?

Today I did an update on my Debian 6.0.0 installation, which included a kernel update. I also did an Nvidia driver update, afterward. All well, until upon a third boot up an fsck check was forced (34 mounts). Some odd behavior ensued. At about 19% it exited the check, printed what appeared to be a load of inode numbers with error messages, and "froze" with the caps lock and num lock lights on the keyboard flashing.I did a couple of grub recovery modes, each which advanced a little further, and all is well again. However, it concerned me. Where in var/log do I find the file of that particular fsck activity?

After a massive update including grub (not the problem) I cannot mount and boot because of the dubject error message. /root (dm-0) and swap (dm-1) are ok its just /home (dm-2) that appears broken.

When I do a forced fsck, I would like to have a log file to look at after boot.
When I check /var/log/ there are no files there with fsck output
I've run force fsck in these ways:
shutdown -rF now
-and-
touch /forcefsck

I'm trying to perform an install of F14 (fresh install over F13), and it has been showing "running post-installation scripts" for 1 1/2 hours now. I am wondering if this is unusual and what the implications might be of power-cycling and rebooting. I'd note this is a fairly fast machine with 2 quad-core Xeons (I forget their model number).

On two Centos5 servers, yum gives a segmentation fault error when trying 'yum update' or 'yum check-update' after running 'yum clean' :
[Code]....
The error is the same for the other computer except while attempting to update the rpmforge repository. Nothing has really changed on the servers in some time and 'yum update' worked fine on each yesterday and I have no idea why they would both suddenly fail!

Just got back to attempting to play with 10.04 using its Live CD. It consistently goes to the "Log In" page and not the Live CD page on running. I saw a Post specifying a F key to be pressed on boot-up to get to the desired starting point some time ago, but did not write it down. Some advice did say press Any Key but this does not seem to do the job. Tried to use the search function here but no joy. Can anyone remember which F key? Note that as a check, I tried to use 9.10 Live CD and this worked fine, so it is not a machine problem.

I'm going to create either a live CD or USB to demo Ubuntu on my Intel Mac Mini. I'd be doing this only to test one piece of software under Linux.
Is it possible to run the software from my live CD or USB just as I would running Linux (thus, without the need for the software to be installed on a HD)? If so, where do I need to save the software file(s) when creating my live CD or USB?

HSo basically i'm trying to run the ubuntu live cd from vista and it doesn't boot up when i restart my computer like it says it should. So i tried finding it in the boot list before windows starts and i only find windows there, no CD. I then tried installing the software that comes on the disk to help if the cd won't boot, and that fails when nearly done giving me some "invalid argument" notice..

No matter what distro I have used, when I run a live cd/usb installer... even without installing the OS or accessing the OS hard drive, Windows 7 freezes after logging in. Running this on an Asus G73-JH, I've seen similar problems from other people with Asus notebooks, but they have actually installed the linux OS. Running Windows home premium x64

Dell 64 bit laptop with no hard drive, I'm running 10.04.2 from a 4 gb flash drive in persistence mode (Linux Live USB), and I'm trying to get ..... to work. I've tried everything on Adobe's site, and several methods from the forums. what's the trick to installing flash in either Firefox or 64 bit Chrome on a 64 bit system? The last method I tried was here, and the terminal said 404 not found after the download command.
I can usually find this stuff myself, but my eyes are getting watery, and my throat tight, and (sniff) I think

We have an old server running, and I decided to run fsck.ext3 -n on the disk to check it (while it was running). Turns out it reports lots of errors - not a good thing.
The weird thing is that when booting up a rescue cd and running fsck.ext3 on it, it says there are no problems with it. The filesystem is marked clean. Forcing a check with -f turns up nothing.
Now, when booting it from disk, fsck complains about an unclean file system that has not been checked for like 50000 days (obviously an error). Running e2fsck -n /dev/sda2 turns up errors again - not necessarily the same ones as the last time.
This makes me wonder: Can running e2fsck on a mounted file system cause errors? I ran with -n which is not supposed to do anything, just doing a read-only check. On the other hand, I heard checking a live file system might throw erros since the files being checked might change while bign checked, thus causing false positives.
Can the old version of e2fstools (1.38, approx 2005) mean non-existing errors are shown? Both the rescue cd and the system use this version.
In any case - why would the file system report errors on boot-up when the rescue cd just said it was ok? It should have been marked clean by now.
For laughs, I shut down the system and booted Knoppix which has a quite recent version (1.41.12, May 2010) of e2fstools. It showed no errors on the file system.
What do you think - are there errors or not on the file system?
The system is actually running Suse, but this is not about Suse specific things - just general Linux tools. And I use Ubuntu personally.

I've been asked to create a Linux build which will contain open source vmview. Simple enough, but I would like to have this deployed onto different desktops from an imaging server using multicasting, we use Symantec Solution Suite 2.5 therefore the smaller the image the better for us. I would also like the image to be fully manageable i.e log in and add / remove apps etc but all it will need is a user account, a root account, web browser, rdesktop and vmware view open client.
I have gone down two routes:
1. There are Live-CD's out there that can do the important things that I want which is to use vmware view and I do like the fact that it is compatible with all our current hardware so I am happy to use this for the time being but I hate the fact that we have to boot it from CD as we have quite a few PCs in the room. I would like to convert the distro to boot from HDD exactly as you would from a CD but cannot seem to find a solution to this.
2. I have created a Debian and a OpenSuse build which does exactly what I want albeit taking a bit more disk space than I would like, but my issue is how do I capture and deploy this to different hardware as our imaging server only does cloning.

I have a Dell Inspiron 6400 running Windows 7 64bits and Ubuntu 10.04 64bits. My problem is that when I'm connected to my wireless router the connection crashes when I watch a live stream video such ..... or something else. It does not happen when I'm connected via cable to the router nor in Windows 7 when I'm connected via wifi.

Is there any sure-fire way to identify whether the current Ubuntu system is running in Live mode or not? I want to distinguish between Live mode and running from installed HD, and do some processing in boot up script. FYI, in grml, the /etc/grml_cd file only exit in Live mode file system; no such file if running from installed HD.

I am trying to run the openSUSE live cd from the second partition of a 16 G USB stick. The reason for doing this is so that I can use the first 13G as a windows file system that Windows can read. Does anyone know how to do this?
