General :: E2fsck Two External Arrays At Once?
Mar 11, 2011If I umount both of them, can I run an e2fsck on each at the same time through 2 putty sessions, or will that not really gain me anything from doing them one after another?

General :: External Drive Read Only - WARNING! Running E2fsck On A Mounted Filesystem May Cause SEVERE Filesystem Damage
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! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

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?
General :: E2fsck For Only One Volume On Reboot?
Feb 9, 2011I know if I do a shutdown -rF now, it will perform an e2fsck on all my volumes with the -y switch. But if I just want to check one of the volumes rather than all of them, and have it use the -y switch so it will automatically answer yes to everything, how can I do that?I'm using RHEL, and have a huge volume I need to run a check on, and I dont want to sit there for the next 24 hours hitting the Y key every time it finds a problem ;-)

General :: Automate Reboot And Possible Pending E2fsck's?
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.

Jul 6, 2010So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:

Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.

I didn't touch the contents of the external hard drive, but now I can't mount it and the various xfs programs seem to demand that it be mounted in order for them to change anything.Anyone have any ideas on how to change an xfs partition from external log to internal? Failing that, how do I get the information off it?

But how do i know which dev it was associated with in /dev/? Since i had to test something, i plugged it out, and save the output of ls /dev/ > ~/result.txt
after plugging the dvd-rom, i compared the results and was able to find that it was associated with simple cdrom i.e. /dev/cdrom. I wanted to know that is there any command that will tell me which /dev/ file was associated with external dvdrom? i tried to see in the following result
1) df -h ( no results, just the already mounted partitions)
2) fdisk -l ( same as above)
3) dmesg | tail (shown almost the same result as was shown on shell at the time of plugging the dvd)

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.

My question is, which i can't figure out from reading the man pages for e2fsck and shutdown, is what switches does it use when it automatically runs an e2fsck on each volume? i'm assuming a -y since it never prompts, but what else? is it physically checking the entire disk for bad blocks, etc etc?
OpenSUSE Install :: E2fsck -b 8193 <device> Error After Win 7 Installation
Jul 30, 2010I had left a small windows partition for some programs like MS Office, (I'd failed to install it with wine :-( ) so I was dual booting OpenSUSE 11.3 & Vista. When I decided to replace Vista with Win 7, the grub was missing, I formated the Vista partition, then tried to boot into SUSE before installing win 7. there was some command line, that i tried the instructions I had found on the forums so I typed
grub
find /boot/grub/menu.lst
and I got (hd0,1) so I
root (hd0,1)
[code]....
I got an error about missing (hd0,1), when I pressed enter I got a menu not the one I was used to. When I chose to boot OpenSUSE 11.2 or the failsafe I got error 17 "cannot mount partition" so found a bit of assistance from the following page: How to fix GRUB after Windows breaks it, and how to edit the GRUB menu - Super User when I press "e" and change root (hd0,1) to (hd0,2) then boot by pressing b, I get the usual SUSE boot screen, then the bootup process stops with some text displayed on the screen. there was a lot of text but the following is what I jotted down: the superblock could not be read or does not describe a correct ext2.
superblock corrupt e2fsck with an alternative superblock

Ubuntu :: Grub Rescue Only Detects HD0 (fsck, E2fsck, TestDisk)?
Oct 15, 2010I (through TeamViewer) helped my mother (who is in Spain) updating her laptop to 10.10. I was of course doing this while doing other things at work, and managed to replace the Grub installation. Now the machine won't boot.
It stops in Grub Rescue.After having a look at the Grub Rescue Mode Megathread I made her type the command
Code:
ls
with the result that it only detects HD0
The previously mentioned thread then says:
Quote:
If all you get is (hd0) you most likely have a partition table or disk error. Seek assistance elsewhere! (fsck, e2fsck, TestDisk, etc.) It used to be (at least) two partitions on the disk, one with Win 7 and one with Ubuntu 10.04. I need to tell her (over the phone) to type in order to make the computer boot again? The laptop is, by the way connected to the Internet. Normally I am so careful when doing stuff like this, but today, I messed it up. And of course it had to be my 2500km's away mothers machine...
Ubuntu Installation :: Superblock Error In Gparted - Can't Run Dumbe2fs - E2fsck
Mar 8, 2011I have Ubuntu 10.10 installed (installed xubuntu on top and that is what I run but should not be an issue) on a laptop and it runs fine but I am giving it to my daughter so I wanted to install windows as well, and dual boot, so she could play a couple of games that she has. When I booted with gparted cd it shows the information icon beside my partition (have 2 one swap sda1 and one for ubuntu sda2) and everything I attempt to do tells me the superblock and all backups are bad. I am not sure how this can be since the system boots and runs fine.
In gparted I can't run dumbe2fs or e2fsck without getting the error but when I do dumpe2fs in the system it seems fine. I am pretty sure I used ext2 or ext3 as a filesytem as it is an older laptop so ext2 is what I usually run with. Maybe I just let ubuntu install whatever it wanted this time, I can't remember for sure which I chose during this install. have been backing up all the data to move it off anyway so reinstalling won't be a big issue. I had checked out how to reinstall grub2 after doing the windows install so thought I was all prepared but apparently I was not that prepared.
Server :: E2fsck Froze At 4.8 Percent On Large LVM2 Volume
Feb 16, 2011We had to reboot a server in the middle of a production day due to 99% iowait (lots of processes in deep sleep waiting for disk iops). That's never happened to us before. It had been 363 days since the last fsck, so it started automatically on reboot. It hung at 4.8% on a 2TB LVM2 volume for about an hour. I killed the fsck and rebooted the server. The second time, it went past that point and is currently at about 62%. First, what causes e2fsck to hang like that? Second, is there any danger in killing e2fsck, rebooting, and starting it again?

May 16, 2011Recently installed Centos 5.6 in order to install Plesk on. Not familiar with Linux partitioning so left the default values at install with a few GB of unpartitioned space left free. Followed the instructions on the Plesk installation manual for adding a seperate partition for /tmp - [url]
Then later on I couldn't get in to the server locally via the GUI (which was already switched on), it just had a black screen so I powered the machine off. It then wouldn't boot back up. When it got to e2fsck I got a [Failed]. I also got the same message as in this thread.
I'm now at a remote location. When logging in as root and trying to run fsck to find and fix any disk problems a remote engineer has found that it won't unmount the partitions so I can't really run fsck on it. He's forced the machine to boot for me and I have SSH access but if I reboot the machine I'm quite sure I won't be able to get in again from here.
Is there something wrong with my fstab maybe?
