When i type the df command i see that /dev/hda1 as a filesytem that is mounted at '/'(root). Is /dev/hda1 a filesystem. I thought that it is a partition on my hard disk that contains the root file system.
View 6 RepliesAfter a hardware failure (overheat of cpu)and solve the problem, some services (mysqld, openvpn,etc..) fails to start because "disk is full".some checks and discover that hda always report 100% used when is not full (i expect 70% are in use),deleting some log files (>100mb) for testing still reporting 100%.. i try use fsck but didn't correct the problem... anyone can help me ?

I installed Debian on my PC and then installed Ubuntu. This worked fine and I could dual boot between the two. The PATA disk was /dev/hda on debian and (I think) /dev/sda on Ubuntu. I copied the entire disk to a sata disk using dd from knoppix and put the PATA one to one side. Now the Ubuntu comes up fine but when I boot debian, it complains about references to /dev/hda1, which is present in grub - root=/dev/hda1. Debian now expects sda references rather than hda references. How do I persuade Ubuntu to write /dev/sda1 to the bootloader rather than /dev/hda1 using grub-mkconfig?

This only started happening quite recently - before this I could boot to Linux quite happily.
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?
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.
I 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?
I want to find out the last time a filesystem was mounted on Linux (Debian).

I don't want to cause damage, but I'd rather not go into BIOS.
I'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?
I 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)
View 1 Replies View RelatedFor 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 RelatedAs per these instructions, I got up to the end of the "Acquiring an Ubuntu filesystem" step (where it asks you to mount the newly created Ubuntu partition) and ran into a problem: The partition won't mount, as the file system type cannot be determined because I cannot remember the file system used during installation. Is there any command that prints the file system type of GPT partitions?
View 5 Replies View RelatedI 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.
My linux distro is CentOS 5.3. Today I edited /etc/sysconfig/readonly-root and set "READONLY" to yes, now my /etc/sysconfig/readonly-root file is like this:
# Set to 'yes' to mount the system filesystems read-only.
READONLY=yes
# Set to 'yes' to mount various temporary state as either tmpfs

I had installed ubuntu 11.04 on my system along with windows vista. After a few days, i decided to remove ubuntu so i just logged into windows and formatted the ubuntu partition using the windows partitioner, then extended my main c: drive to span the whole disk so that i was left with a single partition with only windows vista on it.Later when trying to restart my system couldn't log back into windows.I kept getting a prompt sayinggrub rescue>After googling around a bit i shrinked and created another partition the disk again and installed ubuntu on it again.still. =/GRUB doesn't show any windows entry.I noticed something strange though that when i tried viewing my partitions using parted i didnt see any filesystem type listed besides my windows partition (/dev/sda3). I doubt that is why GRUB does not show any windows entry.Also i manually tried to boot into windows from the grub prompt using commands...root(hd0,3)chainloader +1bootbut it says 'invalid signature'Did i somehow corrupted my windows partition during resizing and installing/un-installing? Plus i also booted with the windows installation dvd and when i typed bootmgr /fixbootit said something like no valid filesystem found.

View 7 Replies View RelatedI am using Gentoo Linux and for a while now, the root file system is mounted read-only on booting. For obvious reasons, this is quite annoying as most services do not start up correctly (I do not use a separate file system for /var). After the system is up, I have to log in, remount the root file system read-write, fix /etc/mtab, mount all other file systems in from /etc/fstab and then start up all the missing daemons. I know that there are ways to make a system run properly with a read-only file system, but I would rather restore the old behaviour of a writable root file system.
The strange thing is that after running mount / -o remount,rw, the file system is mounted in writable mode without any errors. I suspected some problem with fsck, but now I have disabled automatic file system checks on the partition (tune2fs -c0 -i0).When I run dmesg, only these lines mention the partition at all, although I am not sure if not something gets lost because /var/log is not writable:
EXT3-fs (sda5): mounted filesystem with writeback data mode</code>
EXT3-fs (sda5): using internal journal
The line in /etc/fstab looks like this:
