Jan 5, 2011

[Code]....
i am using ubuntu 8.1, please i love that ubuntu version and it's why i haven't upgraded yet because i have tried the other versions and i didn't really like them. i have a 40GB HD and 512MB RAM, 1.8GHZ processor, i am using pentium 4.

I have a Rad Hat 7.0 old Linux system that crashed due to power failure. On reboot the system goes to Checking Root File System and does 92.5% check and fails.
Here are the error messages I get.
I don't know what to do at this point so I say yes and it goes in some wierd mode.
SO I ran fsck manually but I get an error PARALLEIZING FSCK.
I can't fix the corrupted stuff for the system to reboot. THIS IS VITAL.

If you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?
Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.
Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.
I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.

Fsck is not check any file system which are not root file system at boot time.
Normally it run: /sbin/fsck -A -R -C -a
But this command doesn't do anything.
I've tried to strace it, and looks like this:

A little while ago i bought a magazine with the openSUSE 11.1 distro on it but couldn't install it so i gave up. I am attempting to have another go. The problem is that the os will work fine when booted from CD in fail safe mode and can be installed from there but when out of fail safe mode the system begins to boot but freezes and will do nothing more.

A few days I used the wubi installer to install Ubuntu over Windows. This I did on my C: drive. I also have another partition, the X: which now is my D: drive after I used the gparted live cd to give the system partition more free space. No problems so far.
But now, when I use Clementine Player, I see that it cannot find any of my songs in my library and Deluge has to 'check' my downloads every time I open it after a reboot. My theory is that the folder inside /media/, which contains the file system gets a new name (a 16 digit capital letter/number name) every time I reboot my computer - or maybe every time I use Windows and then Ubuntu again? It's pretty annoying,

I did normal net upgrade after the official release of 10.10 yesterday evening. On reboot I get a frozen system with a blank screen. Checking via safemode, I find it is stuck when 'checking battery state' but this is a desktop machine! Apt update, uninstalling ubuntu-desktop, reinstalling ubuntu-desktop, etc.

Recently I installed openSuSE 11.3 x64 on PC with Intel motherboard, 4GB RAM & two of 1TB WD RE3.Of course I set RAID1 during installation After some struggle with GRUB which pointed to wrong devices after installation I started to work. But suddenly I found that file system is corrupted after every reboot (It does not depend on what I use and what the way I use - reboot, shutdown -r now or even just poweroff - everything follow to:
Starting MD Raid mdadm: /dev/md2 has been started with two drives
mdadm /dev/md3 has been started with 2 drives
mdadm /dev/md4 has been started with 2 drives
mdadm /dev/md5 has been started with 2 drives

16GB RAI've been running the Debian-based Proxmox VE on it for six months or so with no problems.Today I loaded Centos 5.5 x64. During a reboot, the file system crashed and fsck couldn't repair.I loaded it again, did all the updates, and loaded my applications. On about the third reboot, it crashed again and fsck couldn't fix it.I don't really know where to begin. I doubt seriously that any hardware has went bad since yesterday.

Centos 5.3 includes Ext4 and improved support for encrypted file systems but it appears to be aimed at laptop/desktop systems, in that a password must be entered at boot time.
Is it possible to have a server with an encrypted root file system boot up without entering a password?
Mandos will do it...
http://wiki.fukt.bsnet.se/wiki/Mandos
...by serving up the password from another server...
http://packages.debian.org/squeeze/mandos
...to a client loaded into the initial RAM disk environment...
http://packages.debian.org/squeeze/mandos-client
...but it's not available on CentOS, and is only in Debian unstable.
Is there a similar (or any) solution for CentOS?
In particular, I'm envisaging encrypted virtual machines being served passwords from their virtual host.
Alternatively, the data that *really* needs to be protected could be encrypted while the system core remains unencrypted. But then the keys to decrypt the file system must be stored in the unencrypted portion, so this is not an effective method.

I'm new to C language and some help finding places in the following code where a system call is made and error checking is not done. I found one but since I don't know C language at all I'm not exactly sure what else to look for. Link to my file: [URL]...
I found one and added error checking:
if (setoutpipe){
//Changes: Added error checking to the system call close()
//Orginal Code: close(pidefd[1]);
if(close(pipefd[1] != 0){
fprintf(stderr, "Could not close piple.
");
exit(255);
}

I need to allocate a % of the total system memory for a buffer but what is the best method to determine how much memory is in the system? So far the only way I have found is to get the pages of memory:
Code:
long sysconf(_SC_PHYS_PAGES)
Is that the only option?

I tried installing F14 and F15 but display resulted in freezing. The display would work upto "Check Media/Skip Test" for media during installation and the system freezes immediately after that. So I did a VNC installation from another system. But the initiation of X would always result in hanging of the box. After googling and trying various solutions, I found a ray of hope in one solution which suggested adding "vesafb:mtrr,ywrap vga=0x318" to the kernel arguments. This resulted in displaying successfully the boot-time flash (Fedora logo being filled with white color) during booting. But "startx" or "inittab 5" result in hanging of the system.
The following is the relevant information:

Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?

I don't think there is a way of doing this with date or clock commands. But maybe they are writing to some file and I can take a look at the file's modification time. dmesg and /var/log/messages show nothing relevant.

I downloaded the DVD ISO version of OpenSuSe version 11.2 64bit from openSUSE. I checked the iso file checksum after downloading and it was correct. However after burning to DVD i booted from the disc and started the install. After getting passed the initial settings and it starts to extract all of the packages each file fails the checksum and will not install. I tried downloading again on a different computer and burning again using UltraISO using the Disc-At-Once method, again checking the ISO file's checksum before burning.
It still gives the same errors. So i loaded windows and started the windows based install and my anti-virus (Kaspersky) says the disc is infected with a trojan. How can the disc be infected when the ISO file's checksum is correct?. The computer that i am using to burn the disc is virus free according to Kaspersky and Norton Technician Toolkit.

I have an output file that looks like this:
Quote:
Now if you see the first line:
Status for ACCOUNT_MISSING_FRM_RCIS_LINK- mismatch
Status for ACCOUNT_MISSING_FRM_RCIS_LINK is ACCOUNT_MISSING_FRM_RCIS_LINK- does not exist in DB
This should appear just once as :
Quote:
The same goes for last line.
For further information the ACCOUNT_MISSING_FRM_RCIS_LINK is a table name and it row count is taken from a log and then Database checked for the rowcount to see if it is a match,mismatch,or the table does not exist!
I am getting the desird output just that i need to do something to this output file.

I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.
Code:
#!/bin/sh
while true
do
$HOME/bin/hpgl.sh >/dev/null 2>&1 &
