Red Hat / Fedora :: Filesystem Check After Power Outage - WARNING: "Running E2fsck On A Mounted Filesystem May Cause SEVERE Filesystem Damage"
May 18, 2011I 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?
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.

OpenSUSE Install :: Filesystem Not Mounted After Freeze?
Feb 27, 2010I installed OpenSUSE 11.1 on a friends computer after having a lot of trouble from ubuntu, and because I use it. It was working great when she got it home, but it locked up randomly and wouldn't unfreeze so she turned it off and when she rebooted She got an error about there not being a file system present and that she needed to run a mount command, which didn't work. After that, now it just says that there is no files system present and you ge tthe basic prompt. I had her run a live cd and run Gpartd and check and repair the partitions, but it did nothing.

Feb 26, 2010I run Windows Vista and Ubuntu 9.10 dual boot. Today while booting windows, it informed me that there was something wrong with my hard disk and it would perform a check, and made some fixes.
Only when I wanted to boot into ubuntu again did I realise that the disk check had corrupted my linux partition. Ubuntu's load screen shows up, but just before the login screen it says that the filesystem could not be mounted.
Is there a way I can fix this? And how do I prevent windows from doing the same in the future?

Mar 18, 2011I've ran fsck -c on the (unmounted) partition in question a while ago. The process was unattended and results were not stored anywhere (except badblock inode). Now I'd like to get badblock information to know if there are any problems with the harddrive. Unfortunately, partition is used in the production system and can't be unmounted.
I see two ways to get what I want: Run badblocks in read-only mode. This will probably take a lot of time and cause unnecessary bruden on the system. Somehow extract information about badblocks from the filesystem iteself. How can I view known badblocks registered in mounted filesystem?
General :: Grub: Kernel Parameter RO But Filesystem Still Gets Mounted Rw?
Jan 13, 2010I am trying to do a fsck on my ext3 partition, but so far failed to let the system come up in single user mode and having the partition mounted read only. It says in the kernel parameter that it is read only (RO) but still mounts it RW. A remount with mount -o remount,ro does not work, since / is always busy. what to do to get a fsck done? I don't want to boot into a rescue system, this should be possible on a running system (like Windows does it, when rebooting)

Nov 19, 2010For example we have a PC with Linux and, let's say, ext4. It is connected to another PC with Linux and Samba-shared dir.First PC mounted shared dir of the second one. So it's in the filesystem, for example in "/mnt/000/". What will happen if I unplug the net cable from first PC? Will ext4 on the first PC crash so I'll have to perform fsck? I know that hot unpluging of mounted HDD probably will make filesystem read-only available and generally damaged.
View 1 Replies View RelatedGeneral :: Ext3 Filesystem Mounted In Ubuntu 9.10 (Echo Error)
Apr 19, 2010I am trying to figure out a totally odd behavior of the ext3 filesystem mounted in Ubuntu 9.10. There is a Korn Shell script, part of which does the following in the loop:
while ((1)); do
mv dir1/file dir2;
if [[ ! -r dir2/file ]]; then
echo "ERROR"
ls -l dir1/* dir2/*
exit 1
elif
echo "OK"
fi
done
Given that dir2/file always exists and that I do not move it asynchronously with "&", my script should never hit the "ERROR" statement. The odd thing is that it does, and quite randomly (no pattern at all). However when it does hit the ERROR case, ls -l prints that file is in dir2 and it is readable! I tried using "-e" instead of "-r" test - no luck. I never seen anything like this in 10 years of my programming experience. Same script worked fine on Fedora 11, and yet it wouldn't work on Ubuntu.

View 1 Replies View RelatedCentOS 5 Server :: Can't Mount Ext4 Filesystem In Centos 5.6?
Sep 7, 2011Summary of issue: EXT4 filesystem won't mount--with error = mount: unknown filesystem type 'ext4'. Is no ext4 in kernel the issue? Or is something corrupted?Really perplexed by this. I updated Centos 5.5 to 5.6 to get ext4 (5.6 is supposed to have full support of ext4). I built several arrays and put the ext4 filesystem on them. All went well until I tried to mount them. BTW, this array (below) is set up as a RAID6 using partition 1 of #8 2TB drives.Bear with me here; just trying to be complete and not waste your time.
Attempting to mount give this:[root]# mount -v /dev/md1 /asc/array1mount: unknown filesystem type 'ext4'Note: it does "fake" mount with ption (which apparently does everything except the system call):[root]# mount -f -v /dev/md1/dev/md1 on /asc/array1 type ext4 (rw,grpquota,usrquote)e2fsprogs:Package e2fsprogs-1.39-23.el5_5.1.x86_64 already installed and latest version (for Centos 5.6; CentOS 6x uses the 1.41...)

CentOS 5 Server :: PHP SOAP Server Returns Array Using NuSOAP Library?
Jul 2, 2009I have a function in my SOAP server that returns an array. When the client calls this function, it only receives "array", and when I use foreach to print each member of this array, it tells me that this is not an array. If I change the returned value of the function to a string or integer type everything works fine though, so I don't think that there is any problem with the client.I am using NuSOAP library on php to achieve that.I had doubt when declaring the type of return value of the function. In XML schema there is no array type, so I specified the return value as a string like this:

CentOS 5 :: DRBD Mounted Partition Not Updating?
Nov 4, 2009I've been working at creating a highly available set of host servers for a linux diskless boot cluster.Each host machine is fitted with redundant power supplies and two 1TB drives in a Raid-1 configuration.When I first started this project they each had twin 160GB drives. In my original setup I had both nodes acting as primary systems so that I could mount /dev/drbd0 to my /data directory and see changes immediately.It had worked in the past where I could make a file in /data on the first machine and it would show up in the /data directory on the second machine. One day this had stopped working where if I made a file on the first machine it would display on the second one until I unmounted /data and remounted it to the /dev/drbd0 disk.
This is when I bought the new disks and decided to start from scratch. The weird thing is that if I make a file on the primary and remount on the secondary to see it and then delete it from the secondary and THEN delete it on the primary, the primary throws no error however it goes into read-only mode because it knows that file was already gone.Below is my configuration file, sda8 is an 820GB partition which is used for all of the data I want to replicate, currently populated with ~10GB of data. Sda7 is my metadisk partition which is 500MB large clearly more than needed by drbd.Also you will notice "incon-degr-cmd "halt -f";" is commented out. This is because when I go to actually use it drbd throws an error when reloading the configuration and I'm not sure why that is either
resource r0 {
protocol C;

However I cannot write to the directory despite it being mounted RW and having read-write access on the host (a Netapp Filer). If I check permissions on the mounted directory, I see it is owned by 'avahi-autoipd':
I have disabled the avahi-daemon in chkconfig, although it wasn't running to begin with. Any idea why this directory would be owned by avahi-autoipd and whether or not that has anything to do with why I can't write to the mounted directory?

I am wanting to connect to the existing Linux fileshare from centos. The know the fileshare is NFS and I know the IP address and directory name. I attempted to connect using the 'mount' command as#mount -t nfs <server IP address>:/<directory> <local directory>An attempt was made to mount, however it is username/password protected. I have gone through the docco for 'mount' and cannot find anyway of passing <username><password> with 'mount'. Does anyone know how? Or am I using the wrong command?
