General :: Dell PE1750 Server Not Boot Up After A Power Failure - FS Check With E2fsck
Apr 19, 2010I have a dell PE1750 server which would not boot up after a power failure. I am thrown to a shell for maintenance after showing an error in file system check. The server was running - Red Hat Enterprise Linux AS release 3 (Taroon). Please let me know if I can try to recover from this error by booting from the 1st CD of a higher version of linux like RHEL5. I ask this because I do not have the old media with which the system was setup. Can the use of latest OS CD cause any problem?

May 15, 2010Ever since my upgrade from 9.10 to 10.4, every time I reboot the system it does a full disk check. /var/log/boot.log tells me that fsck thinks that the file systems contain errors or that it wasn't cleanly unmounted. And yet, it doesn't seem to actually find errors, and a clean reboot starts another check (again with it thinking something is dirty). I dual-boot with Windows, and reboot from there with the same problem.Again, all of this is new with 10.4 and was not happening with 9.10.Is there a way to find out when/how/why the disks are not being unmounted cleanly?

OpenSUSE Install :: Boot Error Because E2fsck Thinks Ext3 Filesystem Is Ext2 ?
Jan 19, 2010During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.

Aug 1, 2011These days I see the disk check that is popping up when my Ubuntu is booting up quite frequently. It says 'press C to cancel' but C (or Shift C or CTRL C or CTRL ALT C) does not have any effect. Pressing CTRL+ALT+DELETE reboots but again ends up in the vicious loop of disk check. How to bypass it? When I need to critically enter the desktop for an urgent pressing info waiting for 20 to 25 minutes disk check is kind of difficult.

Jul 27, 2010I have a volume on my server that according to tune2fs is "clean with errors", so i'm assuming I either need to unmount the volume and e2fsck it, or reboot and drop into maintenance mode and do itThere aren't any live samba shares off that volume, so i'm thinking I could do it without taking the server down, as this server is only for samba shares, which are on a different volume.Could someone tell me if I'm taking the right approach? I've never done unmounting and mounting before, but I've read it can be done manually without affecting how the volumes are mounted when a server starts. i'll have to look up the commands.

Jun 14, 2010Other than when there are errors in the messages log or when you have file system problems, when should you e2fsck volumes? I have a lot of volumes that have 500GB to 1TB of data on them, and it takes quite a while to e2fsck them, so wondering if its something that should be done regularly, or only when there are actually problems.

View 4 Replies View RelatedGeneral :: E2fsck And Unmounted A Volume
Jul 20, 2010I have two volumes, both with 800GB total used on them. lets call them /vol1 and /vol2. /vol2 is just a cron'd rsync'd copy of a folder on /vol1 which is a live share for many users.If I temporarily suspend the cronjob doing the rsync's from /vol1 to /vol2, is it safe to unmount and e2fsck /vol2, then remount it somehow?
Both /vol1 and /vol2 say the filesystem state is not clean when i do a tune2fs -l on them both. According to tune2fs both will check themselves upon restart, but if I can do /vol2 since it isn't the live data beforehand, that will cut my downtime in half the next time i restart the server.But I also wonder that if I can do this, then i remount /vol2, will the "not clean"-ness of /vol1 just be rsync'd back over to /vol2 the next time the rsync runs?

Apr 19, 2010I have a heavily used file server that I want to restart, then if it requires e2fsck's on any volume to run them after it restarts. The only problem is that the server is rarely rebooted, and they said it might kernel panic because its been so long. I've heard there's a way to have it go past the kernel panic if it does happen, but I'm not sure how to do that or the other stuff.If it was a Windows server, I would schedule a shutdown with the force switch, and have the chkdsk's already scheduled for each volume on reboot. But for RHEL, I really don't know.I'm hoping this can be done, so that way I can have it kick off at say 7am, then when I get in at 8am it will probably be near the end of the e2fsck's so I can see what's going on.

Mar 10, 2011I want to perform an e2fsck with the y switch (so I dont have to answer yes to every question) on two volumes on a server the next time I restart it. I don't want to do a shutdown -rF because 1) I dont want to check the other volumes and 2) it seems when I do that, the e2fsck doesn't keep restarting itself over and over to fix all the problems. Seems like it runs once, then if it fails it drops you to the repair console in single user mode. I'd rather just have it start the check that will keep repeating over and over right away, because I know it'll take more than one pass.

General :: Website Compatibility Checks For IE/ Printer With No Driver ?
Jun 4, 2010Currently have just Linux on my main computer (brother built it for me, knew I wanted to try Linux, so just put Ubuntu on).
Old computer (very old, 256MB Ram etc) runs Windows 2000 very slowly, currently will only start up in safe mode (not sure whether this is because it's not currently attached to the router or printer, or whether more serious).
I'd like to put linux (qimo, DSL or puppy probably) on the old computer so my 3-year-old can use it instead of demanding the penguin game (tuxpaint) whenever I want to use my computer!
So, wondering whether to try and shrink the windows partition or whether to just go for linux only. That computer was second-hand as well, so I don't have the windows disks.
The two things I'm worried about:
1) sometimes do some web design, and how would I check whether IE will display my pages without strange problems 'cos it doesn't follow the standards...
2) printing out photos at short notice: husband picked the printer so we're lumbered with a canon pixma MX700. It can do basic printing but won't communicate with linux to do photo quality (no linux drivers...) If I have plenty of time I use a photo printing service such as photobox.
Any thoughts how I can get round these problems so I can just jettison windows without worry? I don't have the spare cash to buy windows 7 or whatever to run in a virtual box...

Mar 24, 2010I'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!

Ubuntu :: E2fsck Fails Device Or Resource Busy
Mar 3, 2011My son's netbook with 10.10 netbook remix failed to boot. Using the Live install CD and Gparted I couldn't repair the EXT4 filesytem. The error reported was:
e2fsck : Device or resource busy while trying to open ...
After trying many solutions and web searching I decided to try a different live CD and tried Knoppix 6.4.4
Using the command interface I typed e2fsck -v -f -y /dev/xxxx (xxxx = your device). This worked first time and the machine rebooted without hesitation.
Ubuntu :: Can Running E2fsck On Live System Cause Errors ?
Jun 29, 2011We have an old server running, and I decided to run fsck.ext3 -n on the disk to check it (while it was running). Turns out it reports lots of errors - not a good thing.
The weird thing is that when booting up a rescue cd and running fsck.ext3 on it, it says there are no problems with it. The filesystem is marked clean. Forcing a check with -f turns up nothing.
Now, when booting it from disk, fsck complains about an unclean file system that has not been checked for like 50000 days (obviously an error). Running e2fsck -n /dev/sda2 turns up errors again - not necessarily the same ones as the last time.
This makes me wonder: Can running e2fsck on a mounted file system cause errors? I ran with -n which is not supposed to do anything, just doing a read-only check. On the other hand, I heard checking a live file system might throw erros since the files being checked might change while bign checked, thus causing false positives.
Can the old version of e2fstools (1.38, approx 2005) mean non-existing errors are shown? Both the rescue cd and the system use this version.
In any case - why would the file system report errors on boot-up when the rescue cd just said it was ok? It should have been marked clean by now.
For laughs, I shut down the system and booted Knoppix which has a quite recent version (1.41.12, May 2010) of e2fstools. It showed no errors on the file system.
What do you think - are there errors or not on the file system?
The system is actually running Suse, but this is not about Suse specific things - just general Linux tools. And I use Ubuntu personally.
