CentOS 5 :: Partition Broke My Computer / What To Do?
Dec 1, 2009
I have created aprtition calls /dev/sdd4 and used mount comand I changed /etc/fstab added the new partition to that file as recomanded on http://www.cyberciti.biz/faq/linux-disk-format/
Now when I reboot my pc I get an error message
( fsck.ext3: No such file or directory while trying to open /dev/sdd2 [failed]
An error occurred during the file system check. Dropping you to a shell; the systme will reboot when you leave the shell.
Give root password for maintenance (or type Cntrol-D to continue) )
When I type the root password it is on read-only I cant chage any file.

Wednesday I went to work, docked and fired up my older Dell C840 laptop (running Fedora 12). It had a long list of updates that it downloaded and installed (it had been off for about a week). When the updates were finished, I noticed that my laptop had locked up. After waiting a while, I ended up doing a cold reboot. After that, I get the Fedora symbol that fills up, and then the screen goes black with a single cursor. You can type in anything and it is reflected- even control and ALT codes. If you hit CTL- ALT-F2, it goes into a terminal mode. You can do almost anything that you'd normally do in terminal mode. The video driver is the original off the install disk, and it's never been changed- it works fine right out of the box.
If I try to start up X-Windows, I get a segmentation fault error. I've tried deleting and then re-installing some of the packages that were updated (trying this via yum), no difference. I don't know what else to do. I need to get this laptop going before next week- it's my work computer and I do use it a lot. Is there any way to get in touch with the people who wrote the updates, and file a bug report? I'm using my main (home) system right now, that for a couple of reasons needs to stay on windoze XP for a few more weeks. I've been around computers for years, but not Linux.

I just ran Computer Janitor on my computer and I think it broke Synaptic. The program was cleaning up some files, but then it froze halfway through and I had to force it to quit. Since then, I can't open Synaptic package manager, the Ubuntu Software Center, nor Computer Janitor itself. When I do they either freeze and I have to force them to quite or they just don't show up on the screen, but they're stuck running in the background because System Monitor reports the processor is running at 100% and so I have to go in manually and kill the bad processes running in the background. Restarting doesn't change anything.Running Lucid Lynx on a HP dc7100, P4 3.2 Ghz, 2gb RAM.

mpg123 suddenly started playing a police siren occationly. I checked the process once I heard it, and root was the process owner. How could this happen? Have someone broke into my computer? If so - how could I verify an attack? I run Ubuntu 9.10.

I have Ubuntu installed side by side with Win7. My Ubuntu partition was (hd0,6). Then I created one Win 7 partition using Win7 before my Ubuntu partition. Win 7 pushed my Ubuntu partition to (hd0,7).
When I start Ubuntu, I get an error
Code:
error: unknown filesystem
grub rescue>
Now, when I do this

I changed partitions (partition X is now partition X+1) and can no longer boot. I get thrown into grub rescue. But even if I get past that, it still doesn't boot. (I can't see why because it's using an unsupported graphics mode by default, but that's another gripe). I would prefer an installation which is not fragile to changes in partition numbers or drive numbers. It's not 1975 any more, can't we use meaningful names instead of 0, 1, 2?

So far I've been dual-booting Vista and Intrepid, and I decided I'd shrink down the Linux partition a bit, expand the Windows partition and reinstall Ubuntu fresh from a Live CD. I booted up from a Live CD, mounted the old Linux filesystem to check that I hadn't missed any documents to back up before I wiped the partition, and then cued up the relevant operations in GParted.
The key mistake I made was not to unmount the old Linux partition first, which led GParted to bug out and, apparently, stop my Windows partition from working. GParted no longer recognises the partition as NTFS - it tells me it's an unknown filesystem, and refuses to move or resize it.
sudo fdisk -l recognises the partition as HPFS/NTFS. Running chkdsk from a Vista recovery disk has been, so far, unsuccessful. What else can I do to either make the partition bootable again, or at least access it from Linux so I can pull my files off?

In an attempt to shrink my Data partition on my 500GB drive I had succeded in shrinking it but I think I have broken the partition table as now it refuses to mount. When trying to mount I get this error mount: wrong fs type, bad option, bad superblock on /dev/sda2 I have done some searching around but most fixes haven't worked because they are based on ext2/3 File systems and this partition is ext4. Using Ubuntu 10.04 x64.

I have a RPS (server with iscsi storage) that worked fine ! I yum updated it yesterday in order to upgrade it to 5.6.
After upgrading, the server can't reboot at all ! I can't find anything in logs
When i boot it via a kvm, the load screen says :
kernel panic - not syncinc : VFS : Unable to mounr root fs on unknown-block (2,0)
Pid: 1, comm: swapper Not tainted 2.6.34.6-xxxx-std-ipv6-32 #3
My kernel is on a netboot, it is 2.6.32, and i work on an ip failover.
The ipfailover continues to ping, but not the 'true' ip adresse
I assume it is a iscsi bug, but i don't know how to fix it. Or maybe it is something else.

After updating and installing Mysql's TOP, yum broke. When trying to clean, update, or install, the following error occurs:
dingle@its:/home/dingle# yum update
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named cElementTree
Please install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the current version of Python, which is:
2.4.3 (#1, Sep 3 2009, 15:37:12)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]
If you cannot solve this problem yourself, please go to the yum faq at: [URL]
I tried to resolve by reinstalling the dependency, didn't work either:
dingle@its:/home/dingle# rpm - [URL]

Preparing... ########################################### [100%]
package python-elementtree-1.2.6-7.el4.rf.i386 (which is newer than python-elementtree-1.2.6-5.i386) is already installed
How can I rebuild YUM appropriately so it will operate correctly?

After installing the latest updates (the second round of updates since the upgrade from CentOS 5.5 to 5.6), Evolution mail barely works on my KDE desktop.After I do manage to get it running, then exit the program and log out, bonobo-activation-server and a couple of evolution process invariably continue running, and must be killed manually.The program generally does not start at all using the desktop program icons. If I make sure bonobo and all evolution processes are dead, I can generally get it started using the command line, but it complains with this error message:
[edfix@eagle ~]$ evolution --component=mail
** (evolution:6324): DEBUG: mailto URL command: evolution --component=mail %s

libnm_glib_nm_state_cb: dbus returned an error.
(org.freedesktop.DBus.Error.ServiceUnknown) The name org.freedesktop.NetworkManager was not provided by any .service files
I tried reverting to the previous kernel (2.6.18-238.5.1.el5), but no improvement. System data is at [URL]

I am running CentOS 5.6 on my servers (auto-updating to the latest patches). A couple of days ago, a number of updates were applied:
glibc-common-2.5-58.el5_6.4.x86_64
glibc-2.5-58.el5_6.4.x86_64
nscd-2.5-58.el5_6.4.x86_64
glibc-headers-2.5-58.el5_6.4.x86_64
[Code]...
This update broke a software tool from Xilinx (FPGA compiler). I rolled back all of the above, to 2.5-58.el5_6.3, and the tool works OK. I get:
/home/cad/xilinx/ISE13.1/ISE_DS/ISE/bin/lin64/unwrapped/map: symbol lookup error: /home/cad/xilinx/ISE13.1/ISE_DS/ISE/lib/lin64/libXst2_Core.so: undefined symbol: _ZN5boost7archive6detail17basic_oserializerD2Evmake[2]: *** [map] Error 127

is it possible to use a Windows-based recovery partition on a dual-boot computer to overwrite the Ubuntu partition and remove the GRUB loader? For instance, if you booted up your computer, accessed the hidden recovery partition and used it to reset the computer to it's factory default settings, would that effectively remove the Ubuntu partition and the GRUB loader? Would a completely new installation of Windows overwrite/uninstall Ubuntu and GRUB automatically?

Trying to install Centos 5.2.i386 from DVD in text install (I'm assuming I need to do text install as I'm setting up raid arrays)
I have 4x150Gb raptors where I want the following layout:
/dev/sda/
/dev/sda1 100Mb (for /boot in raid 1, 4 disks)
/dev/sda2 1000Mb (for swap, raid 0, 4 disks)
/dev/sda3 4000Mb (for /, raid 5, 4 disks)
[Code].....
In the last attempt I did, sdb,sdc and sdd all had the correct ordering of partitions, but sda looked like above, which means I would need to assemble by boot array partition array as /dev/md0 = /dev/sda3, /dev/sdb1, dev/sdc1, dev/sdd1
Why is the partition numbering moving around as I create them?

3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?

I have a laptop that came with Windows Vista (64-bit) installed. I created a new partition and installed XP (also 64-bit) alongside it.Last night I shrunk my XP partition and created another new partition and installed Linux (CentOS 64-bit) on it. I made an error in judgment and didn't allocate enough space, so I need about 10 more gigs for the Linux partition. It boots up and runs, but I need about 10 more gigs of storage for the files I want to keep on the partition (and yes, they have to be on the partition, I definitely need to know how to do this, not a workaround)I went into Vista and shrunk the XP partition by 10 gigs, so now I have 10 gigs of free, non-partitioned space.
As it stands, when I start up the computer I get the GRUB boot loader. I can boot my Linux install or choose "Other" and be taken to the Vista boot loader. From there I can choose XP or Vista to boot.So, my question is... what is the best way to append the 10 gigs of free space to the Linux partition? Is this something I should do inside of Linux? I have the option to do it in Vista, but the partition shows up as "healthy" but without a file system type.I just don't want to screw up the boot loader, partitions or anything else.This isn't my area of expertise, so if anyone could give me a good suggestion or solid answer

I am using an old username which I have been tied to since my first install, any time I have tried to change it in the past lead to problems such as duplication of files and permission access.
I have a small / partition and a larger /home partition where I store media etc, and on freshly reinstalling Ubuntu 10.10 on / today I was tempted to use a preferred more accurate username and change the computer name - would there still have been consequences to this, if so can they be addressed post install, or can I some how simply just change my username and computer name without confusing my system from here without reinstalling?
*I carried out the re installation using my old usual username and computer name.

I am running vista 64x and i partitioned unbuntu 10.10 on my computer.
I deleted the ubuntu partitioned from my computer through Vista and made it all one drive. SO now all my computer has i the recovery partition which is 9.61GB and the main Vista partition that is 287.65GB. That is ALL.
I restarted my computer and it gives me the following error:
error:
I know you have answered millions of questions about that error, however the problem i have i cant find a solution for anywhere.
Now, i have a GParted disk to manage my paritions because i have had this problem before. However when i put it in the computer it only shows my 2 partitions. (The recovery one and the vista one) Both of them are "unmounted"
How do i disable grub from loading through something like GParted that is boot loaded off a disk at system startup? I only have vista on this computer, but i cant get to it because GRUB is in the way. (I do not know if its grub1 or grub 2, but its ubuntu 10.10)
I DO NOT have a recovery disk for my vista computer, ive lost it, however i have the Windows 7 Upgrade disk, but that will not load from the disk when i turn on the computer.

I have a dell inspiron 9300. I have Ubuntu 10.04 LTS.on't have the root password.Something I'd like to do would be to have two separate ubuntu's on my computer. I'd like to keep this one just as it is but also have another ubuntu-same version- that I can boot up into, and have it default booting up into the old one. How exactly do I do this? I know very little about computers. I barely mastered registration for this site, and copy/paste is a rather new skill for me.

One of my disks in my computer crashed, it was the one containing /boot and some data partitions. The other system and /home partitions were on a second disk, which is ok.
I was wondering, can I create a new /boot partition, and keep on using the rest of the system? Can I somehow do it with a chroot from a live/installer disk, run grub, and use my system again? I have another disk which I can put in the system, but there is even an unused partition on the disk which is ok (but it is rather big for /boot).

My Ubuntu 9.10 is intalled on a partition on my computer HDD. The other partition OS is Windows XP. My Windows uses McAfee as the antiviral program. Granted that linux is at a much less risk for viruses, some still apparently can slide through on incoming emails from Windows computers.
1) Will my Windows partition McAfee protect the entire computer?
2) If not, suggestions for an anti-viral program?
