General :: Filesystem Failures While Running From SD Card
Nov 27, 2010
I removed the hard disk from my EeePC and used it with Debian Squeeze on a 16GB SD card. It wasn't fast, but it was all solid-state, and that's important to me. However, lately it had started misbehaving. When recovering from sleep it'd lose all fonts (everything was displayed in squares), files could not be found and programs would stop working, and in a short time the system would become completely useless. Then after a while it started doing it regardless of sleep mode; I'd turn it on, do something, and it would work for a while - or maybe not - and then screw up. As an example, I noticed that unmounting partitions from gparted would do it almost always, but unmounting them from shell wouldn't.
Sometimes simply opening the browser would cause this weird crash. When shutting the system off it'd complain about the ext4 partition, though I don't remember exactly what it said. I thought it was Debian that had somehow screwed itself up (or I had...), so I wiped the card and installed Ubuntu Netbook on it. I was quite surprised to see that that, too, failed in the exact same way. I'd blame the SD card, but the strange thing is, the data on it is perfectly fine. In fact, I temporarily fixed the problem by reinstalling the hard drive, dd-ing the whole SD card on it and then expanding the partition over the unused space. From this setup, the system works perfectly - using the same data from which it used to fail when running from the SD card.
I've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.
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?
I'm running Kubuntu 9.10, and I like it (yay!) But I've been having issues with sound. Especially under system load I've been having an error where it says that the device analog 9xxx has failed falling back to digital, then it says almost immediately device digital 9xxx has failed falling back to analog. At this point any programs playing sound seem to retain that ability as long as I don't close them, but any programs I open have no sound. This applies to webpages and flash, as well as internal programs. I have also been having issues with video, no errors, but the video skips and freezes. Flash video occasionally crashes and any flash games that submit data (e.g. high scores) to a remote system crash my browser.
I end up having to pause the video and move it back several frames, then wait as if it had to load from ..... for a while, and it will run again for some time. My hardware is a dell inspiron e1505 on which the only things I have done are to replace a broken monitor and upgrade the ram (that is, after I broke windows too many times and converted to Linux. I don't have more error data for you, I simply haven't had the foresight to stick it into a text file yet. The error is displayed in the Notifications and Jobs button in the system tray, which is not well suited to copying and pasting, and I'm admittedly unsure as to how to find the error. I learned BASH on Sun unix at my local college and I still haven't quite learned all of how to speak ubuntu's terminal.
I have a netbook ASUS EPC S 101 She runs XP SP3 on her main drive, a 16 GB SD card. She has available another 16 GB SD card, which shows up as a drive under �My Computer�. I would like to install Ubuntu on the spare card, keeping Windows on the main drive card.
I have a toshiba netbook, and I'm running linux slackware 13.The sound card is an HDA intel.So far I've ran alsaconf and configured the above mentioned sound card. I've also gone into the alsamixer and unmuted everything and turn the volume up.I get absolutely no audio.
i'm using RHEL 5.0 with ext2 or ext3 filesystem, now i wish to use ext4 without loose this Opreating System.... or without using another distro of linux...
I'm about to have a web server at home for the first time. I've always missed having full control and not having to contact my hosting company when I need to do some specific changes - and some changes they won't do for you at all.I've chosen the non-GUI Ubuntu Server with LAMP, and nothing more is installed really except for a couple of command line tools from the repository. The LAMP software has been locked down as good as I can by following some guides on the net and using common sense. Like Apache 2 don't have access to the file system except for the www folder, and setting the headers to Prod. MySQL has skip-networking and I've commented out the listen string to localhost. PHP has a truckload of functions that I've disabled in the php.ini, also by following some guides on the net, among some other security enhancing php.ini editing.
The only thing the server will serve is a well known PHP forum and some html docs, and that's all. Nothing advanced or complicated stuff, and I'm definitely not programming PHP myself or letting anyone do it for me.But I do want to sleep well at night knowing that my server is always on and sitting on the edge of my home network! And can I do that? I've heard that you don't need to be worried about getting your Linux server box hacked, but you should be worried about anyone getting root access to it. But is it really that simple? Ubuntu is shipped without root account and you must have the sudo password, right? What's the odds for anyone to get full access to my system?An issue: I've heard that Apache never must run as root. When I do a ps -ef, I see that there are several www-data processes running apache, but there's one root process running apache too. Is this normal and is it safe?An issue: I've heard that PHP can fail pretty easily. But isn't PHP running under apache 2 and limited by the www-data filesystem access?An issue: MySQL is running as a MySQL user, and I guess that's an unprivileged user right?
I have opensuse 11.3 installed, and my motherboard has the intel i845 chipset, one day windows had enough of the intel graphics chip and would not let me have anything but 640x480 pixels, well you cant do much with that so I put an ati card in and disabled the intenal graphics. windows was happy enough but suse could not boot - more specifically could not mount the root filesystem, saying it had errors (did a very quick fsck), could not find the journal, and I had a bad superblock. the "failsafe kernel" was no better. If I take the ati card out suse boots fine. however I do swap frequently between windows and linux and changing graphics cards between boots is somewhat irritating.
At first log-in as user all was fine yesterday. Today I must have rebooted for the first time because it was all different. I tried to log-in to KDE this morning and it failed with some weird error messages that don't repeat here. It seems it all boils down to the fact that the /tmp folder has the wrong permissions. Whatever I try it always has the permission 755.
It is an encrypted /tmp permission mounted in fstab like this:
I tried to go into rescue mode and change the permissions of the folder, but nothing helps. In rescue mode it is like it is in my OS 11.2 on another computer:
I got out of kde used soma a cli radio station player, got back into kde and sound was screwed up, couldn't restart sound had to reboot, thought it was soma problem. Got out of kde, did nothing for several hours, got back into kde and sound was screwed up, couldn't restart sound had to reboot. Had kde running couple days, xmms stopped playing music, no matter what I tried with preferences I kept getting no sound or sound card not configure properly, had to reboot. Is there a sound log or something that might hint at what's going on?
I also found posts that say to rmmod snd_atiixp_modem because it clobbers the regular snd_atiixp module but snd-atiixp-modem is not loaded. Toshiba Satellite M55-S1001 (Celeron M 1.6 GHz, 2 GB RAM, 60 GB HDD)
I currently have a Raid0 setup with two disks and I have no problems whatsover. I currently bought 3 brand new 1B drives and I set up Raid5. I created the array and everything works fine. I formatted the array and mounted it. When I tried to copy 750gb of data over my new array, it copies fine at some point and it fails. After reboot, I am seeing the array inactive. I tried everything and could not get the raid back active status. I have removed the array and recreated again, formatted again. When I started copying my files over, exactly same thing happened.
I'm having problems with my php 5.3.3 installation when trying to access remote domains. The problem only happens when the PHP scripts are run via Apache 2.2.15. The problems appear to affect all functions that might access a remote domain (e.g., gethostbyname, file_get_contents, curl, etc.). Basically, pHP scripts can't resolve a remote host when run via apache.
So I thought I might try to reinstall curl (I'm OSX 10.5.8, btw). I ran configure and make fine and then make test reports the following:
Code: TESTDONE: 485 tests out of 485 reported OK: 100% TESTDONE: 586 tests were considered during 283 seconds. TESTINFO: 101 tests were skipped due to these restraints:
i just migrated from fedora to debian, and i already love this system. it only seems that i am facing a serious problem with this graphic card.running on debian 8.3.booting my system, i do get this message:
[8.167619] [drm:radeon_pci_probe] *ERROR* radeon kernel modesettingfor r600 or later requires firmware-linux-nonfree.
after that the system seems to run normally except of the fact that it doesn't look well and i cannot set the appropriate resolution for my monitor.

already tried both, the open source and the proprietary drivers, and both cause serious problems.
i tried to install the proprietary driver following these instructions: URL...
after restarting the system i get a black screen with a blinking cursor at the top left corner, and that's it.
then tried to install the open source driver following these instructions:URL...
but after restarting the system my monitor goes into some sort of a "sleep monitor mode", and that's it.in both cases i wasn't able to boot the system through the recovery mode, so i didn't know what else to do and re-installed the whole system each and every time i tried a driver.let's say i have installed the system like 5 times in the past 12 hours.

I'm using a RHEL5/Centos5 variant. After struggling with various 2 TB hard drive failures, I started using the Hitachi Deskstar and Ultrastar models, and had none of the earlier green feature related or QA problems I had with all others. However, I began seeing SATA controller freezing under heavy loads, like large rsync mirror operations. My controller is an on-board ICH7R running in AHCI mode. The symptoms are that the drive goes off line and begins to log thousands of SMART errors for Spin-Up Retries. Analysis confirms that the drive is 100% OK after, except for the huge SMART log. This happens on two servers, and multiple drives. Changing the drive to 1.5 Gbps interface speed reduces the problem greatly but does not eliminate it.
I'm working with Hitachi engineering on this, and their only theory is that it has to do with "non-zero buffer offset". Apparently this is a feature of NCQ to receive data out of sequence, and Hitachi says that ICH7R is supports NCQ but not this feature. I am told that BIOS is supposed to filter offending commands but BIOS vendors sometimes err. An alternate is to filter them at the driver, which I believe is libata. Does anyone know anything about this issue? Where might be a good place to make a query about this, with regards to libata? I've contacted the motherboard vendor about the BIOS issue, but I'd like to look into libata also.
I am trying to disable accounts after 5 unsuccessful login attempts. I am following the guidelines in this article:

This is on an Oracle Enterprise 5.4 box, which is essentially RHEL 5.4 Here is what my /etc/pam.d/system-auth looks like:
-------- #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run.
[code]....
Unfortunately, the account does not seem to be locked or disabled. As root, runninng 'su test2 -c <some-command>' always sucessfully runs <some-command>, and leaves the failed attempt count at 6. /etc/shadow does not have an * or ! anywhere in the encrypted password for the 'test1' user.
What am I doing wrong? I thought that with the max attempts set to 0 in faillog, that the deny= parameter would be used. I thought I should be using su <user> -c <command> from the root account to test if the disable feature is working.
I need to scrape logfiles and do some pattern matching for a series of hardware and system faults;
For example: Network interface down / up IO errors Out of Inodes Out of Diskspace Memory Errors Power Failure
When the appropriate Strings appear in the log (assuming /var/logs/messages)Then a trap will be sent. (Customer specific SNMP solution) So what I need (I think) is a list of the strings I need to match.Has anybody any idea where I can find a list of strings which will definitely appear in the log - RHEL5 ?
I am currently having problems with my RAID partition. First two disks were having trouble (sde, sdf). Through smartctl I noticed there were some bad blocks, so first I set them to fail, and readded them so that the RAID array will overwrite these. Since that didn't work, I went ahead and replaced the disks. The recovery process was slow and I left things running overnight. This morning I find out that another disk (sdb) has failed. Strangely enough the array has not become inactive.
Does anyone have any recommendations as the steps to take ahead with regards to recovery/fixing the problem? The disk is basically full so I haven't written anything to disk in the interim of this problem.
I need by searching this site so I haven't had a need to sign up since I can't really help anyone as of yet. With that said here is my problem: I'm running a VPS with CentOS RHEL 5 host-in-a-box, I just did a rebuild of the server and after a day or two pure-ftpd and sshd unexpectedly close out any incoming connections. I am the only one that uses ssh and ftp so I'm not sure what the problem could be. I checked the logs and there is nothing to do with not being able to bind on the address.
I tried connecting through ssh in verbose mode and it connects to the server just fine, but drops the connection before it asks me for my key pass phrase. If I enable password access it will drop before it asks me for it's password. I've tried restarting sshd and ftpd. I've tried rebooting the machine. I've tried google, but this problem seems to need a little more specific trouble shooting. I can get in through console access, but that doesn't help me much when I need to transfer files.
I've been unable to successfully get a viable Celestia package created under -current with the 13.1 Slackbuild. First off, to build Celestia in the "default" Slackbuild manner, that is to say with the GTK front-end, you need gtkglext. (The Lua package built without issue.) The problem is, gtkglext will not build. It gets to the part of the build where it builds the "scanner" library (I have no idea what this library does in specific), where it successfully compiles, but then fails to link. The newest release of gtkglext is 1.2.0, which is from 2006, so I think that some of the symbols it is looking for when linking against -current's updated GTK libraries are depreciated. Here's the last bit of output from the failed build of gtkglext:

"error: 'abs' is already declared in this scope"?? There's a function or variable being declared twice that can't be right. Maybe two headers use the same variable or function name, and they're winding up in the same scope Like I said, I don't know. Hence, this post. I really like Celestia. I could live with the mystery of why these things won't build, but I can't seem to find any pre-built binary packages out there.
Of course, you can't try the KDE front end, since it will only work with KDE 3.
Trying to install 10.04.1 Kubuntu desktop to Toshiba T110 laptop running Win 7, 4 Gig Ram, 32 bit o/s. Downloaded iso from Ubuntu web site and burnt DVD. No matter what I do I get the error message "cannot mount /dev/lop0 (/cdrom/casper/filesystem. squashfs" etc. Searched by Google and this forum, tried various remedies Unebootin; USB drive boot up etc etc; still get same message. Is there a workaround for what seems to be a fairly common install problem?
I just installed Ubuntu 9.10 and I was messing around with some settings and all that. I went to System > Preferences > Appearance > Visual Effects. I then proceeded to enable the "Extra" option. I was prompted to restart my computer for the effects to take place. Now it is running somewhat slow, for example when I open up Firefox, or any other program, it loads very slowly. I went back to change the Visual Effects back to "None" but it was already on that option, I don't know why. I went to my Hardware Drivers and I didn't have the recommended graphics driver on, so I put the recommended on and that had no help.
Hi, So brand new to Ubuntu and linux for that matter. Can't seem to get my network card up and running I have tried the various fixes through the forums, as you can see in the screenshots. Just hoping an expert could help me out so I can finally close the box and get sleep. I have a ASUS M4A78T-E with phenom II. I downloaded ndiswrapper (1.9) and have wicd. The card is trendnet 643PI but it shows up as RealTek 8190.
I tried ubuntu for a few weeks, but I couldn't get the nvidia drivers to work, I tried everything. So, I got sick of that, and went to download OpenSuse, which seems to be even nicer (..... ) I downloaded the 11.1 liveCD (gnome) from here. I nicley got the welcome screen, and the option screen (liveCD, check errors etc.). I chose LiveCD and it started booting, I got the splash screen with the loading bar, and after it completely loaded, the screen turns black with a lot of messages and at the end:
Code: GdmLocalDisplayFactory: Maximum number of X display failures reached: Check X server log for errors. Great, I hoped for better luck after Ubuntu.. My sys. specs: Asus F3Sc 32bit Intel CentrinoDuo
