Hardware :: Permanent Filesystem Corruption On Reiserfs - Ext3 And Ext4 - Disk Failure?
Feb 9, 2010
I have been having problems with filesystem corruption on my eeepc 1000H for a long time now. I have tried using different filesystems, kernels and distributions (arch, slackware) to no effect. I am starting to grow suspicious that this problem lies somewhere else, as I haven't seen anyone else having similar problems in such a variety of scenarios.
I have tried testing my ram using memtest86+, didn't come up with anything after a full run through. I also have tried using e2fsck -c to check for bad blocks, it finds none. I had a go at using smartctl but wasn't really sure what I was doing. I did a long test and it came up with nothing anyway.
This problem is in addition to the problems I've been having with my intel graphics chip and KMS. A lot of the time there are lockups when booting into X, which can only be gotten out of by a hard reset. This is sometimes what causes the original filesystem errors. I've stopped messing around with KMS for now to eliminate this but my current system in unbootable. I'm guessing my disk is wrecked but have as yet seen no definitive proof. Can anyone recommend anything that I should do?
I am currently on ext4 with a custom kernel 2.6.33-rc6 (the stock kernel shipping with slackware does not have the elantech extension for psmouse included). When I was using arch, I was just using the stock kernels.

When I rebooted my system (RHEL 5.3 x86_64), I got the following error when it was booting up:
Code:
Full screenshot of the bootup error messages here: previous bootup error
So to try and fix this, I booted from the OS disk and did a linux rescue.
Here's some of the results of the commands I did:
Code:
Here's a screenshot of the output from fsck after it's done, notice it says 0 bad blocks but the system was modified:fsck results
I then reboot but now I get the errors:
Code:
Full screenshot of the startup errors I get now here: current bootup error
Does anyone have any ideas on how I can fix this? Was the fsck I did initially the correct thing to do to fix that initial group descriptor error or did I make things worse?

I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog
I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:
And here my filesystem types:
This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.

I'm wondering if anyone knows what will be Squeeze's default filesystem. Will it be the proven ext3 or the newer (sometimes faster, sometimes slower) ext4?
I currently have ext4 and I have nothing to complain about. In fact, my overall experience has been very positive. Ext4 is definitely faster when fsck runs during boot.
What would be the cons of having ext4 as default in Squeeze?

I have installed ubuntu to my pc. i made 3 partitions. one for system, one for data and one for swap. two of them were ext4. after some time i have reinstalled ubuntu again. but this time i didn't put to format the second partition, but just mount it using ext4. after that i cannot open my files. checked with gparted shows that 2GB used, but with df 188MB. and in properties writes ext3/ext4 filesystem. i used chown, chgrp but didn't help. please help, these data are ver important. i cannot lose them.

The laptop I regularly use is out of use after having tried to upgrade from ext3 to ext4, following the instructions that can be found at namely, Step 2: Upgrading to Ext4Well, the first step was done without problems, but when I reached "Mount your filesystem", the problems started:When typingsudo mount -t ext4 /dev/XXXX /mntwhat appears is:UNEXPECTED INCONSISTENCY; RUN fsck MANUALLYStupid me, I did nothin but jump to the next step:gksu gedit /mnt/etc/fstabWhere I only got a fully white screen with no written text at all, instead of the menu that should have appeared, as can be seen on that webpage.
However, after running Gparted again, it showed the extension as EXT4, not EXT3, so I thought the system had automatically upgraded. Then I proceeded to boot the system, and this is where the massive failure appearedAfter seeing the Ubuntu logo for a while, the system directs me to a blank screen with the message:Mount of filesystem failed.dc5123-ec01-4438-8bd6-cb85bb080f87A maintenance shell will now be started.CONTROL-D will terminate this shell and re-try.root@hihihi-laptop:#So I type CTRL-D:

/dev/sda1: One or more block group descriptor checksums are invalid. FIXED
/dev/sda1: Group descriptor 0 checksum is invalid

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:
Quote:
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
(initramfs)
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
[Code].....
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!

Is that possible, I mean when I upgrade F10 to F11 with yum upgrade is there a way to 'upgrade' the filesystem to ext4 for example (with the exception of boot partition)? Or I have to reinstall fedora like new?
While changing the filesystem can I do it by parts? what I mean is for example: I have 2 partitions like '/' and '/home' with ext3, so I backup data in '/home', change '/' to ext4 then mv files from '/home' to '/' and change '/home' to ext4 and finally mv those files from '/' to '/home'. Is that possible?

OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?

When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.

I've just bought a new SSD hard drive:Kingston SSDNow V-Series SNV125-S2/128GB 2.5'' 128GB SATA/300The question is which filesystem whould you recommand and why?BTRFS vs NILFS2 or EXT4?If you choose ext4 would you enable jurnalling?I'm very close to choose Btrfs.Any experience with running any of these on your SSD?

I just read about reiserfs being way faster than ext4. I am installing lubuntu 10.04 on a Pentium 4 3.06 ht 512ram. Ide 150g this distro will be use only for running a small counter strike source server the system already ave ubuntu on ext4 and win7. So my question are..
1- Can it install my distro on a reiserfs?
2- Is it better?
3- Is this different from other file system. I mean can it be logical?

I had 5.4 machine. Upgraded to 5.5 today via yum upgrade. All went fine. Rebooted. Wanted to convert root partition to ext4 (I have three partitions: /boot, / and swap). All of them on software RAID 1 (root is /dev/md2). I did the following for converting
yum install e4fsprogs
tune2fs -O extents,uninit_bg,dir_index /dev/md2
nano /etc/fstab # I indicated here that my /dev/md2 is of ext4

I'm migrating my OpenSuse 11.3 (which was update from 11.2, 11.1 ........ ) to a new hard drive. My partitions were reiserfs and in the migration I'm "converting" them to ext4, the conversion process is simple and it works fine for all of them except the root one:
1) I create a new partition on the new hard disk (bigger than the original one)
2) I format it with ext4
3) I copy all the data with cp -a from the original partition to the new one
I already have all the partitions migrated to the second disk, then I have tried to do it with the root partition:
-I've booted with a system rescue CD and I've done !9 2) and 3) with no problems.
-I've edited and changed al entries in fstab and grub conf (menu.lst) to point the new partitions
-I've reinstalled grub and it seemed It will be no problems booting, but
It begins booting, the grub menu appears, It begins booting the kernel, but suddenly:
waiting for /dev/root to appear: OK
fsck.reiserfs -a /dev/sda2
........
mount -o ro,ad,user_xattr -t reiserfs /dev/root /root
and it fails, because sda2 is not reiserfs, but why does it try to mount it as reiserfs if I'm not saying anywhere it is reiserfs?
This is my fstab:
Code:
#/dev/disk/by-id/ata-ST3160211AS_6PT0V05Y-part2 / reiserfs acl,user_xattr 1 1
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part2 / ext4 acl,user_xattr 1 1
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part1 swap swap defaults 0 0
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part3 /home ext4 defaults 1 0
/dev/disk/by-id/ata-ST3500630A_9QG94AT1-part1 /mnt/backup auto noauto, defaults, users, exec .....
I've booted it also with SuperGrub2 disk and the same thing happened, so I think it's not a grub problem but I don't wknow why it tried to mount the root partition as reiserfs.

While trying to boot into the normal user the system aborts the login and tells me that /home does not have write permission.
The login manager gives:
Code:
If I log in as root and do a
Code:
Or to open some files, it works and no problem seems to exist.
All this happened for the first time after running luckybackup to fusion the old files of one home directory under EXT4 with the new files from my notebook (ext3, Opensuse 11.1 KDE3) in order to come to a unified home. But then the system did not boot any more. I tried to change the owner but some files did not have write access (not even as root, "the file does not exist"). So I thought I might have a a file system problem.
So I thought: unmount the /dev/sdb1 and then do a fschk on it. Runs and was perfect. So I did run it with forcing to control inode per inode.
No error.
So I thought: you screwed up the system. I then decided to reinstall OpensSuse11.3 from the scratch and create the same user for home. I formatted the rest (/swap /boot /root) and left only /home. Installation runs brilliantly, all ok, it comes to the login..................

I'm trying to RMA a month old SSD, and they're giving me a hassle about it. The drive currently seems to work just fine, but I'm 95% sure that a few blocks went bad and corrupted some data about a week ago. I was able to mostly recover the data and correct for the bad blocks, but I don't really trust the drive anymore.
I'm running an up to date Debian Squeeze install with ext4 on this drive. My system started doing some bizarre things, to the point that it was unusable, so I rebooted it. As it was booting up, it complained about needing an fsck, which found dozens of non-trivial errors that it was mostly able to fix. It then proceeded to boot normally, except the drive mounted itself as read only (due to errors). Another fsck turned up a similar number of problems. This happened a couple of times before I ran fsck with '-c', which is supposed to scan for and work around bad blocks. That seemed to fix the problem, it hasn't given any more problems since then.
The manufacturer is refusing to RMA the drive unless it's completely unmountable right now this minute, saying that it was a one time problem that could have been caused by anything. Am I right in thinking that the problem has to have been with the drive if 'fsck -c' fixed it, or could something else be going on? If it was the drive, am I somehow being unreasonable in asking for a new one while the current one is "working"?

Is there guide for converting ext3 to ext4 on Fedora? I use Fedora 12 which is regularly updated. How safe is procedure for data, I have only one ext3 partition on disk which has one ntfs and that ext3 partition (and also one small swap partition).

I'm currently using Ubuntu, but just ordered a new SSD (64GB) & plan to install Fedora on it- but just have a few questions...
- What is Fedora's position on MONO & MoonLight?
- I will be leaving /home on my 600+ BGB HDD, but root, /usr & swap will be on my SSD- will there be any potential issues?
- What format should I use (Ext3, Ext4, XFS...) for my SSD?
- Any recommendation of rpm repo's I should add?
- Will FGLRX work with FC13 or FC12

I'm using CentOs 5.4 (2.6.18-164.15.1.el5 #1 SMP Wed Mar 17 11:30:06 EDT 2010 x86_64). I tested out ext4 on a partition for the last few months and it seems to work fine. The issue is that quotas dont seem to work correctly on it. Is there a way to revert back to ext3? Mainly the quota tools do not work on it.

I am going to do network upgrade of my 8.04 to 10.04 LTS. I have a dual boot with Vista, and currently I can read Ubuntu partition from Vista using Ext2fsd. However, I read that using Ext2fsd with ext4 (default in 10.04) is problematic because of "extents".
My questions: Will the upgrade convert my current ext3 partition into an ext4 one? How can I keep the ext3 partition? The release notes for 10.04 say:
The simplest way to select a different file system such as ext3 at installation time is to add the partman/default_filesystem=ext3 boot parameter when starting the installer.
