Software :: Booting On Centos 5.6 - E2fsck - Failed - Fstab Wrong ?
May 16, 2011
Recently installed Centos 5.6 in order to install Plesk on. Not familiar with Linux partitioning so left the default values at install with a few GB of unpartitioned space left free. Followed the instructions on the Plesk installation manual for adding a seperate partition for /tmp - [url]
Then later on I couldn't get in to the server locally via the GUI (which was already switched on), it just had a black screen so I powered the machine off. It then wouldn't boot back up. When it got to e2fsck I got a [Failed]. I also got the same message as in this thread.
I'm now at a remote location. When logging in as root and trying to run fsck to find and fix any disk problems a remote engineer has found that it won't unmount the partitions so I can't really run fsck on it. He's forced the machine to boot for me and I have SSH access but if I reboot the machine I'm quite sure I won't be able to get in again from here.
Is there something wrong with my fstab maybe?

I decided to implement quota on /home file system, but unfortunately I had not separate partition of /home file system. So I made entries in fstab at root (/) partition as follow:-
Label=/ / ext3 defaults,usrquota, usrgroup 1 1
and reboot the system, but my system could not give me login screen and after a longtime giving many "read only files" error ends up at following error message:-
"I could not start the X server (your graphical environment) due to some internal error. Please contact your system administrator or check your syslog to diagnose. In the meantime this display will be disabled. Please restart gdm when the problem is corrected."
I also got single user mode and try to remove changes whatever i had made recently but it gives me read only fstab file.

I added an sshfs entry fto /etc/fstab in a fresh FC15 build ona laptop and this seems to work
sshfs#user@server:/opt/apache-tomcat-7.0.2/webapps/ /mnt/server/opt/apache-tomcat-7.0.2/webapps/ fuse uid=500,gid=500,allow_other 0 0
I can mount and umount /mnt/server/opt/apache-tomcat-7.0.2/webapps/ without problems.
But after a reboot the systme it hangs when loading, I can't copy paste the messages but it said something about boot dependencies, and it was apparent the error was loading fstab. I had to Ctrl D or enter root password to get a recovery system, after commenting out the sshfs line (and some nfs lines too) from /etc/fstab after another reboot I was in.
sshfs used to be permitted in /etc/fstab it seems , I've not used it before, could this be a FC15 issue? I have seen other threads about FC15 and nfs boot issues presumably to do with the new booting mechanism.

I have already started a thred here about RAID failure: RAID5 failed, system drops into limited single mode - openSUSE Forums
I was not able to boot the system until I commented /dev/md0 in fstab
Why is it so?
This is just a files sharing partition, it is not a system partition.
Is there any option to always ignore any errors and continue boot?

I have two versions of Ubuntu on my computer - 10.04 and an earlier one that i no longer use. I'd like to free up the space that the old partition is taking, but the computer boots from the grub menu.lst of that old version. How can I make the boot process use the menu.lst in the 10.04 partition?
where is the boot process situated anyway and how can you get at it?

Got a HP dv6-3019wm laptop yesterday and my attempt to dual boot has gone up in flames. I first followed the tutorial [URL]
I might have gone wrong by accidentally making the hard disk 'dynamic' after shrinking the windows partition. Upon booting the computer up after the 11.04 installation, Win7 gave me a 0xc0000225 error. The built in hard drive recovery didn't work and neither have multiple win7 64b recovery disks I have downloaded. A gparted live cd wouldn't boot. On attempting to reinstall 11.04 (so I can just get rid of win7), the installation freezes when it tries to recognize the state of my hard drive.
I've basically turned to dban, but that won't even work. The latest version gives me an error of "no configuration file found" and 1.0.7 give me "non-fatal error", even when I attempt to auto-nuke.
Am I out a hard drive?

I recently installed another Linux distro, Kali Linux, alongside my Debian 8 and discovered to my chagrin that my computer boots to Kali's grub rather than to the Debian grub. I had spent some time customizing Debian's grub and would hate to see that effort go to waste. Is there a way I can get my computer to boot to Debian's grub instead? I tried deleting Kali's boot partition with gparted but that did not seem to do anything.

Grub use to open an old kernel I tried to edit /boot/grub/menu.lst to open the one I wanted. The edit gets saved but it still opens in the wrong kernel. i.e when edit menu.lst it has no effect. I have tried running sudo grub-update. I've read piles of forum entries to no avail. I am running Jaunty.

I added a script to start a service and Lenny wont boot anymore,its stuck at the point where the script is supposed to load. I used update-rd scriptname defaults I was trying to add NTLM Authorization Proxy Server, by adding a script
Code:
python /root/ntlmaps/main.py
This is the second time i am trying this, that last i did this i added a & at the end( this should send it to the background?) and it worked fine.I have mounted the root file system through live-cd, but iam not able to figure out how to undo this silly mistake of mine
Edit: I just managed to get the system back up. Looks like i was confusing /mnt/etc/init.d with /etc/init.d ...
I added the & to the end of the line, making it
Code:
python /root/ntlmaps/main.py &
I referred to [URL] while doing this exercise and apparently there should be some code for shutting down too, dont really know how to do that, on the command line i use kill 9 <PID>, but theres probably some other way for it here...

A friend of mine upgraded his pc to ubuntu 10.04. Sadly enough we ran into issues with his graphics card, which apparently doesnt work well with lucid. We decided to downgrade to 9.10. I did this by installing over the old partition and chose to import the settings from the old account.The problems started when the pc booted for the first time:The list of kernels in grub2 was the one from 10.04.Somehow grub2 from the old installation seems to be still around and messes everything up. Any ideas how I could fix this?

I have a PC104 running debian. I have 3 hard drives (in addition to the one booting) mounted in fstab by UUID. I use the options defaults,error=remount-ro. However, this means that when I boot with the hard drives not attached, I have to press Ctrl-D to bypass when the boot discovers the drives are missing. Is there a timeout commandoption I can add to fstab so that it automatically continues booting even if the hard drives are not attached? I could not find anything on a timeout command. (I tried adding timeout=1000 but no-random guess)

I was trying to update (from 11.0) to 11.3. Booting from DVD, selecting root (after "show all partitions", because none was offered at all), there is a message "No fstab found." and then "Failed to mount target system".fstab on target root is definitely readable and OK. (this is a dd copy from my current system, which is fine.). The target root fs is ext4 (seems ok, see y2log):

I've had two hd's in my box forever. for more space and backup reasons. Well I have started running the Debian Squeeze distro since December. I've had many issues, some are still unresolved. but now I'm running into major headaches with the fstab. Specifically dealing with/wondering why UUID's are used instead of the old /dev/hd? I was a little annoyed when I tried Kubuntu to find /dev/sd? used instead of /dev/hd? but that was workable. But the UUID's are a nightmare. Here's my problem.
My main box is finally giving up the ghost. The mobo is dying. So in order to do some tests I took my hd bundle (my two hard drives with their cables) physically out of the box and temp installed them in a test box. I wanted to do some benchmark and other tests. I got all kinds of errors. I found that the system wasn't recognizing the UUID's listed in fstab. My concern is when the new mobo gets here next week I won't simply be able to plug the hd's in like I always have been and just let Linux reconfigure itself (Debian used to be good about this). I really don't want to have to clean reinstall if it's not needed.
So for this I have two questions. WHY developers decided to drop using /dev/hd? or even /dev/sd? ?
And is it possible to revert fstab's listings back to the old /dev/hd? settings. In debian fstab had lines commented out showing how each partition was listed in it's /dev/hd? status during install.
I'm getting really sick of all these archane changes in ALL aspects of linux that don't seem to have any good explaination or need.

I have been running a server for 3-4 years now, and my shares have been mounting just fine. Well, the network admin looked at a backup and seen that the last date backed up was june. I got to looking around and seen that the share is not mounting. I can mount it with sudo mount -a, which tells me my syntax is correct. I get an error about IPv4 socket not opened and it is aborting the operation when I run dmesg | tail, since I can use the above command to mount later, it sounds to me like it is trying to mount before the network connection is ready.
I have done some looking over some init scripts and found that in the /etc/rc.d/init.r/netfs script it has a line that states that it is checking to see if the network is up before it starts to mount the filesystems and the such. This is set to no, my question is, can I change this option to yes and get my desired results, waiting for the network to be up before it mounts the filesystems.

I have installed a 2TB drive in my dual PIII 866 with 750MB ram. The drive is properly installed and I have configured the drive with 1 partition in RAID1. The array loads fine, but when I add the entry to mount the /dev/md2 /data/repository the following error occurs The filesystem size according to the superblock is 488378000 blocks The physical size of the device is 488377986 blocks Either the superblock or partition table is likely corrupt I have run fsck manually with no errors reported. I have removed the partition and rebuilt the array. The array assembles properly and I can manually mount the /dev/md2, but as soon as I add the entry to the fstab I get dropped to a shell after a reboot. Not sure where to go now?

I downloaded the minimal boot image and installation CDs for F12 i386. On booting either I get the following messages:
Code:
This kernel requires the following features not present on the CPU:
cmov
Unable to boot - please use a kernel appropriate for your CPU
Looks to me like the installation media for i386 doesn't have an i386 kernel! I'm trying to install to an i586 CPU.

I have ubuntu 11.04 with virtualbox installed. I have some old vmware virtual machines on an NTFS partition that I am able to successfully boot with virtualbox at my ubuntu desktop however, when I vnc into my desktop from a remote location and start up virtualbox and try to boot my virutal machines, I get:
Quote:
Failed to open a session for virtual machine.. the virtual machine has terminated unexpectedly during startup with exit code 0.
result code NS_ERROR_FAILURE 0x80004005
component: MACHINE
interface: IMACHINE
from googling this some people have indicated this means my username is not in the virtualbox user group, but I am logging in with the same username over vnc as I do when sitting at the machine where virtualbox works fine. the directory the machines are on is mounted, not sure why I can't boot them what else could be causing my problem? has anyone ever setup vnc4server on ubuntu and got virtualbox working?

I'm trying to install a dual booting machine with OpenSUSE v11.1 32bit and CentOS v5.2 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v5.2. The installation went fine with two notable exceptions:- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub onfiguration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's menu.lst file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.
After completing the installation, I tried to search for a template or guiding on how the menu entry in menu.lst should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error 13: Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :
marte:~ # file /mnt/vmlinuz-2.6.18-92.el5xen
/mnt/vmlinuz-2.6.18-92.el5xen: gzip compressed data, from Unix, last modified: Tue Jun 10 19:20:51 2008, max compression

I installed from a live CD when it came to selecting the partition I re-sized the partition that Ubuntu was on because it was 68 gigs I shaved off 15 gigs for SUSE. Then I selected this new 15gig partition to install SUSE on, everything went fine with the installation I was tinkering around on SUSE but of course I needed internet access, so I go to get on Ubuntu where I had my file with my network key. I restarted expecting to see the usual GRUB boot-loader screen only now with an added option for SUSE. Instead I see an entirely new layout for the GRUB boot loader and all that is listed is SUSE, Failsafe SUSE, Windows XP, and Floppy. The Windows is my XP install and it loads fine sadly it is actually what I'm using now because it is the only thing left that I have my network key saved so I can get on this forum.
Looking on SUSE I notice that the 50gig partition formerly known as Ubuntu still exists I figure no problem add the partition back on to the boot-loader and I'm good to go. Added it and when I select to load it nothing happens it starts to then reverts back to the OS list. Does anyone A) Know how to resolve this or have any ideas. B) Think I can at least copy files off that 50 gig partition to an external hard drive.

As I walked in my office this morning, before getting withing 5 feet of my computer, the computer started an unscheduled auto reboot but failed. After hard reset, unplugging, etc., it will still not boot off of primary system. Used Live disk of previous Ubuntu to gain access to system. Found bug#407862 regarding 'rsyslogd was HUPed' but don't know what that has to do with this specific problem. [URL]. The initial error message on screen was something like "no system disk. Insert system disk and press enter", as if I had a non-bootable CDROM inserted, but there was nothing like that.
/var/log/syslog says this:
Nov 30 07:59:05 my-computer-name rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="908" x-info= URL] rsyslogd was HUPed, type 'lightweight'.

I have just installed Fedora 12 on a 10GB partition separate from the pre-existing Windows XP partition. My problem is that when I turn on my aspire one ao751h it doesn't give me the option to boot Windows XP even though when I mount the partition with XP on it the files are all still there. I think it has something to do with GRUB which I have never dealt with before or the way I set up the partitions when installing Fedora 12. How would I change the start-up screen to allow me to boot from my XP partition as well?
