Ubuntu :: Installation Crashed After Power Supply Failure
Mar 8, 2011
My pc had hardware malfunction; power supply interruption. At this moment it is working stable. My Windows 7 installation is ok but Ubuntu Maverick which I used during crush has malfunction. When I start to boot it looks like this: I had to make a foto so you all can see the problem. all my important files are stored on Ubuntu partition..
today my desktop crashed due to power failure. When i again started the machine and tried to boot Ubuntu i m getting the following message in command screen:- "Minimal BASH-Like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists is possible device & file completions."
I just recently installed Ubuntu and my power supply cooling fan won't power down normally when I would run windows tho it would power down after the system was finished starting up. How can I remedy this?
Is it technically possible to use just one power supply for more than one motherboard?The reason for asking is that I have a number of old (a few years) boards that I would like to use to make up a blender render farm yet only have one spare PSU. Having looked at the pin spec URL...pin 16 (power on) should only be connected to one board (or have a manual switch to ground for on)Pin 9 (standby +5v) probably should only connect to the one board or none and the other (or all) boards would need pin 9 to be tied to a +5v pin.All the boards would network boot and have nothing connected to them, no disks, floppies, monitors, etc; as all data would reside on a network server.
is this a good combination to use with 8 GB of RAM and 2.6 GHz AMD Hex core? The power supply will be replacing a 450 watt power supply and the video card will be replacing an ATI 5750 1 GB (Which currently doesn't work without 10.9, so far) The problem with these is that it doesn't meet the AMP rating of 38A of the GTX 470.
I have a 500GB WesternDigital Elements external harddrive and recently I plugged it into my computer and noticed the green light on the power adapter didn't light up anymore. I'm assuming that the power adapter failed - is this a fairly safe assumption? I know it COULD be something else, but does this at least make sense to move forward?Coincidentally, I've been researching new externals to order a 1.5TB because the 500GB is full.
I'm contemplating two options: 1.) Replace the power supply for ~$40 2.) Take apart the external and mount it internally
If it is in fact the power supply it might be the best option to just replace the thing and have 2 externals for backing up data on. But if it turns out to not be the power supply I'm out $40.I'm not sure how taking apart the external and install the hard drive in a desktop computer would be. Is the harddrive a standard drive? Does it have all the same power cords a normal computer would? If so, I could just install it into my brother's desktop and retreive the data that way (and he'll have an extra 500GB hdd).
I have installed on my computer Solaris10 (64bit version), PCBSD8 (64bit) on 2 primary partitions and 7 Linux distributions (Redhat,Debian,OpenSuse,Fedora,LinuxMint,Slackware,Ubuntu) on the extended partition. I know this might be a stupid question, but here it goes: I have a problem with my actual power supply unit (the fan doesn't work as it should) and I will change it soon. Is there a problem with any of the Linux distributions if I change my power supply unit? I mean, will the Linux operating systems work properly with a new power supply unit or do I have to reinstall all Linux distributions?
So now that it's working the Server can't be seen from the internet. I see that the router changed all the ip address so I changed the fort port forwarding on the router and still not working. And the external ip address has not changed.
My router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?
come across with this issue for one server we are giving support please,help me to know why this issues occurs and alsothat i want a command to display power supplies for the server.please,let me know if anybody is familiar with these kind of issues.
I was upgrading my ubuntu(9.10)/xp machine to ubuntu(10.4)/xp . but there was a power failure and was running in backup for 15 min. But after that the system shutdown automatically. Now when i boot, grub appears and after selecting the ubuntu partition i get a error saying cannot find device.
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.
I was updating the kernel and left the computer to let it do its business. There was power failure and I don't know if the update completed or if it was in the middle of it. Now if I start the computer, it freezes up at the login screen. I tried to recover from grub, by selecting "Ubuntu, with Linux 2.6.32-21-generic (recovery mode)". There were no prompts for input after this. The recovery screen is not updating anything after:
[2.348886] EXT4-fs (sda1): INFO: recovery required on readonly filesystem [2.349015] EXT4-fs (sda1): write access will be enabled during recovery [2.577641] EXT4-fs (sda1): recovery complete [2.578072] EXT4-fs (sda1): mounted filesystem with ordered data mode Begin: Running /scripts/local-bottom ... Done. Done. Begin: Running /scripts/init-bottom ... Done.
When I come out of that screen (ctrl-alt-del), the problem repeats.
I learned yesterday that doing a massive upgrade on my system while moving was a BAAAD idea.The upgrade process was going along just fine, it was all downloaded and was actually installing that last time I saw it. I unplugged my laptop to move a bookcase out, and completely forgot to plug it back in. After I got back from moving a load, I found my computer was off. I tried to boot up, and I got an error that kind of freaked me out. It reads as follows:
Code:kernel panic not syncing vfs unable to mount root fs on unknown-block(0,0)I'm able to get to grub just fine, and my windows partition loads up just fine, but any of the linux kernels fail similarly when I attempt to load them.I'm sure that I can fix this, I just have no idea how. Probably has something to do with a live cd.
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:
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
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
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!
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 have the old version 8.10 installed in my laptop. The laptop already some battery issue and after the power failure i cannot access the external usb drives anymore.I have ntfs-configuration installed and do not know how to access the drives using the tool.Every time i try to access the drive it says that i do not have the privilege to mount the volume.
I have a box running Lenny and boot with lilo. Today there was a power failure and now the system is stuck on Lilo ..It doesnt get passed that. I tried to boot in single mode but the same thing is happens. How can I fix this problem
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.
have Karmic Coala runing on an IBM thinkpad X.41. Works great. My home network is all ethernet so I have a router , CAT5 cable to laptop.A coupleof times I've had power outages The laptop carries on as it's on battery power. When the power comes back , the router restarts, it reconnects after a few minutes but the laptop doesn't reconnect to the network seamlessly. On some other Linux distro's I've had running /etc/init.d/network restart will refresh everything. On Ubuntu I have /etc/init.d/networks but running restart In the end I needed to reboot the laptop to get the network back on.Perhaps this is a power management issue with the laptop ethernet card i.e losing power powers down the card and it never comes back up properly.
When I tell the computer to go to sleep and there is a power failure the sleep state is lost. Is there a way to prevent this? I already know about hibernate and I'm using it but sleep is faster and there is no complete loading of the computer (BIOS, Grub and so on) it just goes directly into the desktop. As far as I know the sleep state is done when everything is in RAM and the computer is turned off but the RAM sticks still receive power. Is this true?
P.S. Can this be done with hibernate and SSD drives? As far as I can tell from what I've read it will be the same but with no state loss. Is this true?
Running Ubuntu headless server 9.10 with a RAID 1 on ext3. After a power failure (UPS power button was hit accidentally), I logged into the system via ssh and found that I had lost all data since my last reboot, which was 4 months ago. It was as if I had a perfect snapshot of my machine from 4 months ago. Everything, database files, logs, all report as if the machine had been off for 4 months. Fortunately, I have quality backups of all my data so I am able to recover, but I have never had such a problem before and I cannot figure out what happened.
I had a power failure, now Gnome will not completly start and just hangs almost there. another member of the family was at the computer and when it restarted and something like TomBoy was flagged as no working and the question was asked if they wanted to delete reference or not , so they said yes now Gnome still will not finish loading. How do i repair from the console prompt?
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.
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.
I use an ADSL connection which I 'dial' using the Network Manager. My laptop is connected to the modem through an ethernet cable.
The thing is the place where I stay is prone for power failure. So the modem goes out with the power. It comes back on within a minute when the power is restored but Network Manager doesn't seem to automatically re-establish the connection after it is lost once. I have to manually do it. Hence most of my downloads do not get done.
