Red Hat / Fedora :: Can't Find Any Huge Files In That Filesystem
Dec 22, 2010
I am facing a strange problem in my server, One of my filesystem shows as 3.1G when I execute df -h command and the utilization shows as 83%, but when I cd to the directory /usr/local I could not find any huge files in that filesystem and I have searched for hidden files as well,
groupserver:~ # df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda9 3.1G 2.5G 532M 83% /usr/local
groupserver:/usr/local # du -sh *

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?

So I noticed today that my machines root hard drive had almost no space on it.
I did a disk usage analyzer and I found out my var/log folder is 95GB.
The large logs are:
can I just delete them? also how can I stop this from happening again?

I have a crippled file system after a disk failure and attempt at repairing. Currently the Web Server is running, however I cannot open the filesystem to explore files and view. I am going to do a fresh install this weekend and upgrade system. I have two questions I hope this forum will help with. (Installing new disk and entire server)
1). Can someone tell me how I could copy the http.config file so that I can view my settings from terminal (This took me forever to get right for my environment to get shtml and cgi files to run correctly and I don't wish to lose). I am running Fedora 8, I'm also not sure of the location. (I'm fairly new to linux and not great with the terminal, however that is the only access working.) It would be great if someone added the terminal commands. If I can copy them I could email to my email address.
2). In the past when I have copied web files (web sites) over to the www directory the permission would be incorrect. Is it possible to write some of the web sites to CD (Disk burner is working) and then copy to the new system with permissions correct? Would you give a little how to all web sites are in the www directy. I think that is etc/www/"webdomain name" One thing I might add is all drives will fail it is just when...

I have a 60GB partition with / and home on it. I logged on yesterday and it gave me a warning saying that I had only 1.9 GB of disk space left. I ignored it for a day and assumed that i had too many videos and pics.But the next day i had not added any files or downloaded any software but i had 0B left. I used the disk usage analyser and found that 33GBs came from /var/log. It was from two log files. syslog and daemon.log 16.5GB each!! I opened them up and i found that this line of text was repeated hnundreds of thousands of times.

I'm looking for a fast way to verify a copy of a folder with 150Gigs of data, in 33 files. Some of the files are a few kb, while a few are 20-30Gigs. I've done a file count, which is quick, but doesn't verify that all the files are intact. I tried running md5sum on them, which works, but will probably take as long as copying the files in the first place. Diff works too, but is slow too.

I have a wav file bigger than 8GB. i recorded it on a windows PC. unfortunately wav files cant be bigger than 2GB. somehow i got a file that is almost 9GB. I tried to chop the file under ubuntu into smaller pieces to open it part by part. i used gnome split to divide the file and made 10 parts out of it. now i have these parts of the data which i cant read with no program except for gnome split to merge them together again - which would only bring me to the beginning of my problem. so my question is: is there any other way to open/ split&open a wav file of that size or maybe a way to open the splitted file partially?

how to create the huge.s kernel files on the slackware disks? or at least direct me to a post if there is the same question. I currently rsync my files to Alien BOB's script, and i use syslinux to install from my usb stick. i was wanting to install using a later kernel just for testing purposes. (i.e 2.6.34-rc3 as of this writing)

I examined the problem, and determined that a huge amount of disk space is being taken up by files in /var/log/ The following files:
Code:
/var/log/messages.1
/var/log/kern.log.1
/var/log/daemon.log.1
/var/log/messages
/var/log/kern.log
/var/log/daemon.log
/var/log/syslog
are all over 1 GB in size. The largest is 18 GB. Together, they total 48.3 GB. I restarted the system, forcing a fsck.

Is there any software in Linux to view huge .txt files, say, over 10 megas? I'm now using default "gedit", version 2.28.0, which seems to not be able to open huge .txt files. It's the same case for Windows default .txt browser, but in Windows, "Win Word" seems to work fine. software under Linux to browse huge .txt files?

syslog, messages and kern.log are incredibly huge files that are taking up a lot of space on my hard drive. Is it safe to remove them and/or to reduce logging so it doesn't take such an enormous amount of hard disk memory? If so, how can I reduce the logging so it doesn't produce logs that are 10s of GB in size?Also, mounting a drive places it into the folder /media. Will it become problematic if the size of the mounted drive exceeds the amount of free space available on my Ubuntu partition?

I started getting errors about running out of disk space in root this morning. I hunted up what's taking all the space; var/log is 39GB (Ubuntu is installed on a 50G partition.) It's specific files that live in that directory, not subfolders. The files are:
kern.log = 11.6 GB
messages (plain text file) = 11.4 GB
kern.log.1 = 6.1 GB

I do monthly reports by copying the previous document, update the text and change the images. The images are the same size and numbers each months. Since last month I upgraded my laptop to Natty and suddenly my document went from 942 kB to 10.1 MB in .odt. When saving to PDF the usual size of 472 went up to 1.9 MB. I have searched the net and the forums but haven't seen anything about a similar issue.
I'm not sure if it's an issue that is from the previous document being produced in Open Office and now updated and saved in Libreoffice. Or if it's somehow something to do with the upgrade from Maverick to Natty. I would hope I don't have to uninstall Libreoffice and install Open Office as a solution (which I understand is not entirely easy in Natty, something I read about Open Office being transitional to Libre). I can't email simple documents to customers that's over 10 MB large...

I streamed video through a my computer with mediatomb yesterday. The problem is that now, I got these huge log files. I am running out of memory (less than 1 gb left) as we speak. They're filled with ufw entries, but my question is:
I read somewhere about a program called logrotate that were supposed to keep logs from getting to big, is this wrong and should mediatomb generate 3 separate log files with 5gb of data each for just 2 hours of streaming?

I need to transfer some massive amount of data (2.5terrabyte, many files, directory structure) to a embedded raid-box which has a minimal linux on it (some custom distro from western digital). We tried rsync (version 2.6.7), but it crashes because the filelist is too big for the ram available (fixed in later versions of rsync, but I don't know how to update, it's not debian based and there are no compiler tools). We tried nfs, but the max bandwidth produced is around 1 mb/sec (cpu bound?), so it'd take around 3 weeks this way. Samba has problems with big files (and we have some 20gb files in there).
SCP isn't installed, and would probably also be cpu bound due to encryption I think. So the only option left would be ftp, we're currently trying using ncftp with the command "put -R /path/to/data/" , but it's been running for over an hour, eating up most of the ram, and not using any bandwidth. I think it is still building a file list or something. FTP already worked for a single 20gb file with acceptable bandwidth of about 12mb/sec. Does anyone know a better ftp program (for console) that can start transferring some data or at least display an estimated time for the copy-preperation?

I need to figure out how to arrange for the fastest-possible read-access of a large or huge memory-mapped file. I'm writing high-speed real-time object-chasing software for a NASA telescope (on earth). This software must detect images of fast moving objects (across arbitrary fields of fixed stars), estimate what direction and speed the object image is traveling (based on the length and direction of a streak on the detection image), then chase after the object while capturing new 4Kx4K pixel images every 2~5 seconds, quickly matching its speed and trajectory, then continue to track and capture images until the object vanishes (below horizon, into earth shadow, etc).
I have created two star "catalogs". Both contain the same 1+ billion stars (and other objects), but one is a "master catalog" that contains all known information about each object (128 bytes per object == 143GB) while the other is a "nightly build" that only contains the information necessary to perform the real-time process (32 bytes per object == 36GB) with object positions precisely updated for precession and proper-motion each night. Almost always the information in the "nightly build" catalog will be sufficient for the high-speed (real-time) processes.

My /var/ partition continues to fill up on all my servers, and it is because the logs in /var/log/apache2 or /var/log/mysql are being deleted during log rotate, but their file handles are being held open. Thus, a "du -sh /var/log" shows the correct values, but "df | grep /var" shows something much different.
It seems that the log files rotate, however if I run "lsof | grep deleted" it returns lots of files that are no longer visible in the directory, however refuse to clear themselves off the disk.
The only way I have found to make these log files go away (and thus clear up the disk space on the partition I should have) is to restart either apache or mysql, depending on which process has huge sized log files being held open.
Is it just me, or is this a big flaw in the way linux works, that it can't figure out how to release file handle for a log so the disk space can be reclaimed? This is happening to me a lot lately.
Here is some output from one of my web servers so you can see what I am seeing...
root@web49:~# df -h | grep /var$
Filesystem Size Used Avail Use% Mounted on
/dev/sda8 9.2G 6.1G 2.7G 70% /var

So I'm having DNS issues (with my router it takes too long to resolve) with 9.10. If I'm using GNOME I can just change the preferences. But where do I find those preferences on the filesystem?
I modified /etc/resolv.conf to just use Google DNS and it works great, but then something overwrites it with my router DNS. I guess that's a generated file, but what do I edit to change the generator?

Here is my problem. Grub2 outputs error: unknown filesystem. Then when i use "ls" command it outputs this:
(hd0), (hd0,4), (hd0,2), (hd1) and when i "ls (hd0,4)/ or any of them it says: error: no such disk
So, heres my story. I dual boot vista and ubuntu from my main 320GB hdd. Today i tried to fresh install 9.10 on a different external hdd. The 500GB hard drive already had two partitions, a 30GB Fat32 and the rest NTFS. both of these partitions had about 17GB used on them. I installed off a cd and i shrunk the NTFS to allow for more partitions. I made a 4gb swap as logical at the end then a primary ext4 / partition in front of it. The drives are Fat32 sdg0, ntfs sdg1, then an sdg3 (which im confused about and says is extension), and sdg4 (with linux) and sdg5 (swap). When finished with the partitions it asked me to select where to mount the ntfs and i said /windows. When i tried to boot up it did not recognize my external apparently because it was plugged in via firewire. I switched to usb and it booted but then i got the error message in grub. Also, when i switched from firewire to usb the drive changed from sdb to sdg. How do i fix this problem? Will reinstalling ubuntu fix this? Is there an easier way? I tried reinstalling grub but it did not work.

I've been playing around with an old laptop and a hand full of Linux distros. I found that each Linux has a kernel "vmlinuz" and a initrd "initrd.gz" no matter how you boot the distro it uses these to files. I have CrunchBang Installed on my laptop I put a copy of the ubuntu live disk in the location
/home/user-pc/ubuntu/
I added a new boot option for grub It looks like this
Title Ubuntu
kernel /home/user-pc/ubuntu/casper/vmlinuz
initrd /home/user-pc/ubuntu/casper/initrd.gz
This boots like a normal cd only problem is while its booting it tells me it cant find the file System. This happened for every single Linux distro I tried to boot. Is there something I am missing here is there a way to tell the boot peramiter where the file system is I think what it means by file system is the "filesystem.squashfs" file.
I have 2 questions
1. Is there anyway to tell the grub loader that this is the file system. To make the live CD boot properly.
2. How do CD's work is it not the same?
