General :: Dell PE1750 Server Not Boot Up After A Power Failure - FS Check With E2fsck
Apr 19, 2010
I have a dell PE1750 server which would not boot up after a power failure. I am thrown to a shell for maintenance after showing an error in file system check. The server was running - Red Hat Enterprise Linux AS release 3 (Taroon). Please let me know if I can try to recover from this error by booting from the 1st CD of a higher version of linux like RHEL5. I ask this because I do not have the old media with which the system was setup. Can the use of latest OS CD cause any problem?

After creating a new JFS root file system, boot (actually /etc/rc.d/rc.S ?) fails when checking it with:
Code:
fsck 1.41.8
/sbin/e2fsck: Bad magic number in super-block while trying to open /dev/sda7:

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?

Running 10.10 After a main power failure I can't boot.
It says:
...........
[sdb] Attached SCSI removable disk
[sdc] Attached SCSI removable disk
[sdd] Attached SCSI removable disk
[sde] Attached SCSI removable disk
and stops.
I get a (initramfs) prompt and have no idea what to do with it.
Allready tried to install 10.10 again from a CD. But it also hangs immediately when it starts to install. The liveCD feature works OK and I can access the hard disk. I tried to update the initramfs with the liveCD but it says I can't write since I have only "read-only" access. But if I do "sudo nautilus" I have full access to the disk.

I had a power failure the other day and my server shutdown abruptly. After bringing the server up I noticed that the /var partition came up as read only. I was not able to edit the crontab, not able to write to files within /var/log/ and do other write operations within /var.
I did a mount and it showed that /var was mounted read and write but when trying to run certain operations the system was still saying that it was read only.

Before to describe my problem I want to say that I searched a lot on the internet and I think I tried all the solutions provided by other users to similar problems.
I've got an IBM xSeries 346 server running CentOS 5.5 with all updates applied with yum.
The video card is an ATI Radeon (lspci says: 01:06.0 VGA compatible controller: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]).
Everything worked fine until a bad day where there was an environmental power failure and the server crashed.
I turned it on, I manually check the file system, some files went lost and after the reboot the X server didn't start.
After the first boot I had problem with /etc/rc.d/rc.sysinit, sbin/multipath.static and /dev/cpu/microcode, I solved them and now the message it shows is:
"Failed to start the X server (your graphical interface) It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"
I choose OK and it appears an empty log, if I go in /var/log/gdm and I do an ls -al:
total 0
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.4
-rw-r--r-- 1 root root 0 Oct 28 04:44 :0.log.3
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.2
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log.1
-rw-r--r-- 1 root root 0 Oct 29 04:52 :0.log
So a lot of empty log files.
I press enter on the OK that appears at the bottom of the screen and it says: Would you like to try to configure the X server?
I choose Yes, I enter the root password and appears the following messages:
Couldn't start X server on card 0
Couldn't start X server with old config, trying with a fresh configuration
Then another messages:
Trying to restart the X server, I press enter on OK and it loops the initial message ("Failed to start the X server...)

I have a volume on my server that according to tune2fs is "clean with errors", so i'm assuming I either need to unmount the volume and e2fsck it, or reboot and drop into maintenance mode and do itThere aren't any live samba shares off that volume, so i'm thinking I could do it without taking the server down, as this server is only for samba shares, which are on a different volume.Could someone tell me if I'm taking the right approach? I've never done unmounting and mounting before, but I've read it can be done manually without affecting how the volumes are mounted when a server starts. i'll have to look up the commands.

A week or so ago I ran an aptitude safe-upgrade and while it was updating mysql I suffered a power-failure. Now, this never really happens in Holland but of course this once it happened at the worst possible time.
I've tried a lot of different things to get mysql working again, but am running into all kinds of problems. First mysql won't shut off properly (it does startup with the computer but I can't connect to it at all) during an aptitude purge. If I kill the process mysql seems to purge properly, but I guess this is not the case because I wasn't able to install it then.
Things seem to have gone a bit more smoothly this time, however:
Code:
snek@snek-server:~$ sudo aptitude install mysql-server
Reading package lists... Done
Building dependency tree
Reading state information... Done

The other day I was in the process of updating an install of Debian Testing (Squeeze). It so happens that the power went out at just the wrong time. According to the dpkg log it looks like it was in the proccess of completing the postinst script for the kernel update I purged all the kernels that were installed and reinstalled the most recent version. Mind you, that the machine booted and appeared to be just fine when the power came back on but I had no gui. So after reinstalling the kernel I still didn't have a gui.So I proceded to purge and reinstall kdm, xorg, xserver-xorg & related, and anything else I could think of.All with out success.This machine has an xorg.conf file. I have edited that file to try the vesa driver instead of the intel driver, no joy. I have renamed that file to force a complete auto-configuration of the xserver on launch but no joy.
Code:
(II) LoadModule: "intel"

I'm trying to come up with a startup init script that will check to see if the system was shut down gracefully, or if it is rebooting from a poweroff or something similar?Anyone know of a way to check for this condition with the least amount of room for false positives or vice versa?My intial thought is just a startup script that will will check for a file on startup, and on a proper reboot/shutdown just touch the file. But id like to avoid that type of script if possible,

I run computers that do distributed computing for cancer cures. I'm experimenting with running a version of Ubuntu that is specifically written for DC and can be run on bootable USB drives. The one I'm running now on USB works fine but there is one issue I need to solve. When I reboot the system or it restarts from a power failure I have to reattach the cruncher client(BOINC)to the each project and I lose whatever work units that have started. I don't have this problem if I use a HDD. I'm using an 8GB USB drive with 6GB of DDR3 12800 memory. Can someone explain to a linux novice how to overcome this issue?

Dell PowerEdge 1600SC Server won't boot from Fedora 12 DVD in the drive because it only supports CDs as I found out after the fact. I'm a complete novice @ servers, so if you need more detail, let me know, and I'll try to provide it. This server is around 4-6 years old. it has "PXE" boot, not sure what that means? This particular server has 3 RAID hard drives. As far as I know, they have all been wiped. I looked up the service tag on Dell, and it has: Compact Disk Drive, 650M, I Internal, Half Height, 48X, BlackHitachi LG Data Storage as its CD drive. Thus, the CD drive does not support DVDs, so installation will have to be via a live CD. However, I'm trying to put Amahi Home Server (http://www.amahi.org/), and Live CD/USB stick installs are not recommended unless one is an expert Linux user.

Ive been at this for two days now, and cant make any progress.
First, the details:
Target OS:
Fedora 14, i386
Target Machine:
IBM (e)server, xSeries 306
OS: Fedora v.4
Boot Order:
1. CD...
2. Removable Media
3. SATA...
USB Drive:
adata 8GB
Process:
I used the prescribed live usb creator for windows to fill the usb drive with Fedora 14 i386. Ive attempted to boot from the USB at least 4 times, once from each USB port on the box. No luck. There isnt an option in the BIOS to select the specific boot device. I bring that up because my desktop does have that option, and using the BIOS BOOT MENU, I was able to boot from the USB and bring up the Fedora 14 Installation Menu, no problem.
So, it works on the pc thats on my desk (eMachine w/XP), but the IBM doesnt even recognize it.

I had a power failure during the portion of the upgrade after the reboot where it was upgrading the packages.I tried restarting the machine with the upgrade line in the bootloader but it says it cant find the bootloader. So I rebooted into the working install and ran preupgrade again, and after it reboots, it gives an error the it cant find "root" of the previous installation.even thought the machine boots and works, I cant tell what state I am in. the boot option lines, shows a fc12 kernel designation and the "about this computer" says "release 13"Also the add remove software doesn't show anything.

While using my computer the other day (I was sending an email) it suddenly turned off. I didn't get any low power warning, but I was running on battery and had my iphone charging from a USB port.
As I didn't think there was low battery, I just turned it back on again. As it was booting I saw the battery light flashing, indicating low power. I went to get the charger, but before I got it, mid boot-up it turned off again.
This seemingly damaged something hard-disk-wise.
Upon turning it on again it dropped into busy box with some message similar to this:
Quote:
No init fount. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built in shell (ash) Enter 'help' for a list of build in commands
(initramfs)
That's not the actual message (copy pasted from another post) but the message is VERY similar to that.
If I "exit" busy box, I get a load of message about "kernel panic" before it freezes up.
I have booted a live USB (what I am using now). I thought since it wasn't cleanly unmounted, simply mounting and unmounting would do the trick. I was wrong.
Code:
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
I had previously ran e2fsck (after checking it was unmounted) but it wouldn't run also because it was reporting that the device was already mounted, busy, or being exclusively used by a process.
I don't want to do any more for fear of causing further damage.
I am astounded that such damage can be caused so easily!

the power on my street went out overnight, and I came home to a rebooted computer at the command line. I shut it down and rebooted again, also tried the failsafe mode, but it keeps going to the command line. Looked in the BIOS and it didn't see my hard drive settings. But I can see the HD fine when I booted using the live CD (that's how I am able to post here

I recently installed Lynx 10.04 amd64. Twice now, my entire file system has become unusable -- each time after a short power outage (2 seconds).
In the first setup, I had two primary partitions: 1) / that was ext4; 2) /home that was ext4.
In the second setup, I changed the /home to ext3.
Both times, after booting up following the power outage, I received a message saying that "serious errors" were found in /home. But, after several reboots, I was able to login and use the system. Then, some time later, I would started getting "Read Only" messages when trying to write to the file system.
fsck gave the following message: "/home terminated with status 4". I received numerous "I/O error" on sda messages.
My question: Is this vulnerability due to using ext4 or is it related more to something else in Lynx 10.04? Further, what can I do (other than buying a power backup device) to avoid my file system becoming unusable after a power outage?

I'm using Ubuntu 10.04 64-bit, which is installed to a second hard drive on my desktop. Earlier this afternoon, there were two 10 second power outages in my neighborhood. The first caused the system to restart with no effect, but after the second outage Ubuntu no longer boots properly. The problem is this: When I boot, I get to the grub screen. I have tried choosing four different options (the most recent kernel, a slightly older kernel, and the recovery mode of each). For each, kernel begins loading, but at a certain point the input to the monitor dries up, and after a few seconds the monitor enters standby mode. When I boot into recovery mood, the last message I see before the screen goes blank includes "udev starting version 151" followed by three lines that read "assuming [something that I can't read before the screen goes blank]." The computer itself remains on, but I have no way of knowing exactly what it is doing.
There seems to be no hardware damage as I can boat into Vista, and I can also boot into 10.04 from a USB. I've used fsck to check the partitions on my hard drive and the test came up clean for all of them. Since I only installed 10.04 a week ago, I could just copy the handful of useful files I have to my external drive and re-install, but I'd like to get some experience troubleshooting this problem. My first assumption is some kind of problem with the video drivers or GUI.
