Fedora Hardware :: LVM Crashed After Fsck On Root Partition
Nov 25, 2009
I got 2 HDDs, I had created LVM by two of them. When I was trying to install quota it was saying it is better if you run fsck first message. When I tried to run fsck. It warned me that I could lose some of my data. So it happened. Actually it is worse: I can't boot my Fedora 11. When I try to run installer in rescue mode, it says no linux partition find. When I try to install (just to see partitions) it shows LVM volumes of hdds are ok but the partition which is / (root)partition seems in unknown format. How can I save my datas? Or can i restore my partitions, LVM?

Can't start Ubuntu, stops after first password. I can access files on my encrypted partitions with LiveCD but I wonder if I can install Ubuntu and still have access to the encrypted drives as I can with LiveCD?

16GB RAI've been running the Debian-based Proxmox VE on it for six months or so with no problems.Today I loaded Centos 5.5 x64. During a reboot, the file system crashed and fsck couldn't repair.I loaded it again, did all the updates, and loaded my applications. On about the third reboot, it crashed again and fsck couldn't fix it.I don't really know where to begin. I doubt seriously that any hardware has went bad since yesterday.

UPDATE: This is a bug: [URL] Evidently the problem is with plymouth because a workaround is to add "rd_NO_PLYMOUTH" to the kernel boot options. I don't get a prompt for my disk encyrption pass phrase---just a flashing cursor---but that's a small price to pay for being able to run fsck when the root filesystem wasn't umounted properly.
I have fully updated f13 (as of today) on a laptop with all ext2 file systems (It has nothing but flash memory.) If it's shut down without unmounting all file systems, it drops to a shell and asks for the root password to run fsck when it's rebooted. Every key press is treated as though it were <enter>, with a response to the effect that the password is incorrect.

Is it possible to run fsck on the root file system?
My Ubuntu 10.04 seems to be checking it's fs at boot...
It shows that the file system is in use and can get severely damaged!
Or the only possibility is to run it from a live CD?

I would like to know if there is a way to do an unattended check on the root file system on my servers, *and* send emails in case of errors.
I know you can schedule a root file system fsck during boot time - but the root file system will be mounted read-only - so if fsck finds any problems - it can't email away a warning, or write the result to a file - or can it?
Essentially I would like my servers to do a self-check of the root file system periodically - and to email me if it fails. I just can't think of a way to get it done.

I have pc/os linux 2009 installed and I recently got the following message while trying to boot up my system:
*checking root file system...fsck 1.41.4 (27-Jan-2009) dev/sda1 contains a file system with errors, check forced. /dev/sda1:Inodes that were part of a corrupted orphan linked list found. /dev/sda1:Unexpected inconsistency;run fsck manually. (i.e., without -a or -p options) fsck died with exit status 4
*An automatic file system check (fsck) of the root filesystem failed. A manual fsck must be performed, then the system restarted. The fsck should be performed in maintenance mode with the root filesystem mounted in read-only mode.
*The root filesystem is currently mounted in read-only mode. A maintenance shell will now be started. after performing system maintenance press Control-D to terminate the maintenance shell and restart the system.
Give root password for maintenance:
The problem is, when I enter my password I get an incorrect password prompt. How can I change my password so that a manual fsck can start? Why did this message error message appear in the first place?

Fsck is not check any file system which are not root file system at boot time.
Normally it run: /sbin/fsck -A -R -C -a
But this command doesn't do anything.
I've tried to strace it, and looks like this:

We have a server for which the root password had been lost, and there were no other user accounts set up. Yesterday evening I attempted to reset the root password by booting from the install CD and using VI to clear the root password in the passwd and shadow files. I then rebooted, and the system has halted with an 'FSCK failed. Please repair manually and reboot' error, with a prompt to 'Enter root password' below. But of course the root password isn't known (I had expected it to blank after editing the passwd and shadow files, but it doesn't work), so I have no way of logging on.

My windows partition isn't starting up, gives an error and suggests using chkdsk. However, I cant even reach safe mode or command prompt. I can still access my Windows hard drive through Ubuntu.I am wondering I can use a Linux tool to perform a check on this Windows partition? I found the fsck command, but I am confused about the warning about running it on a mounted system and about what exactly is a mounted system.
Can someone please tell me how exactly I wod go about doing a check on this partition? Its currently located in /media/disk.I can right click on the partition and unmount it. But if I do this, will Ubuntu still be able to see this partition?What command do I use to do fsck only on this Windows partition (and not the whole system and other mounted places)? How do I remount the Windows partition so that I can atleast salvage my data easily in case doing a disk check does not help?

I have two ext3 lv's of 4GB and 10GB in my hda8 partition, and they are automounted by /dev/mapper/ in my /etc/mtab files in each of the four distros (Suse9.3, OpenSuse10.2, kubuntu7.04 and Debian Lenny 5.0.3). Since ext3 is a journalled fs I feel I ought to fsck their integrity every 3 months or so, however I don't know
a) whether they must be unmounted before running fsck,
b) whether I should use a live CD such as knoppix to run the fsck command, and
c) whether I can and/or should run fsck /dev/hda8, or whether I should somehow fsck each lv seperately?

I'm running an Acer Aspire 1830T-3721 dual-booting Windows 7 with Ubuntu 10.10 (Desktop).
Background: So first I dropped my laptop a couple feet while Windows was running. The laptop immediately shut off and then tried to boot. Booting Windows results in an unfortunate "Windows has encountered a problem communicating with a device connected to your computer. The error can be caused by ... faulty hardware ... Status: Oxc00000e9 Info: An unexpected I/O error has occurred." But Ubuntu booted fine, and could access my NTFS files fine, so I was trying to work on the problem from there. I try a few utilities, looking at the partition table, etc without actually applying any changes.
Then I run a fsck on the drive. It loudly warns me that if I continue on a mounted drive, then I'm going to mess things up. In a moment of stupidity I push on, thinking that surely it would ask me for more configuration, or confirmation, before actually starting. The fsck runs for about 1 second before I Ctrl-C it, running some preliminary stuff and then just starting pass 1.
After this, Ubuntu won't boot anymore. Instead, it hangs just after the init-bottom script runs. If I boot with init=/bin/bash, I can get to a shell, and see that my file system is still there, but not sure what else to do.
I've been running off of a SysRescCD LiveCD, from which I've looked at the drive with testdisk. Testdisk reports that "the hard disk seems too small" while showing me the partition table.
I ran a fsck on the Linux partition; it fixed a bunch of things. There has been no apparent effect on the boot behavior.
I can access all my files, back them up, and reinstall Ubuntu, but I'm hoping there's a better solution, perhaps one that will also help me repair my Windows installation (but I'm looking at one problem at a time here).

I wasn't doing anything special on my computer (Ubuntu 11.04) when it just turned off. When I rebooted I was presented with BusyBox. I'm still pretty new to linux, but it appears that root is totally empty. Is there a way to view a log before the system crashed?

When I do a forced fsck, I would like to have a log file to look at after boot.
When I check /var/log/ there are no files there with fsck output
I've run force fsck in these ways:
shutdown -rF now
-and-
touch /forcefsck

This is a Natty system. I ran update manager to update to the latest releases for Natty, and it crashed. I ran it again and it told me it could only do a partial upgrade, and that I should do apt-get install -f. I did that, but apt-get told me the system was locked by another program. Not to worry I thought, I'll just reboot. So I did that, and I think Update-Manager got a lot further through the process than I thought, because my system is borked. It'll boot into Gnome, but when booting up the Boot Screen no longer shows the pretty Ubuntu Logo, but rather a line of text that says "Ubuntu 11.04".
When it gets into Gnome the keyboard and mouse more or less don't work (although the keyboard based Fn+9 and Fn+10 brightness control still works) and there is no desktop background. After about 30 seconds something crashes but I can't click on it to find out what. Going into the recovery console doesn't help either. The latest Kernel (2.6.38-7) stops moving forwards after "Begin:Running /scripts/init-bottom...done". has occurred for the second time. Luckily I still have the previous kernel, which gets to the same spot and then tells me:
"init: udevtrigger main process (390) terminated with status 1" and then "init: udevtrigger post-stop process (394) terminated with status 1".
I then get the message
"The disc drive for / is not ready yet or not present. Continue to wait; or Press S to skip mounting or M for manual recovery". S goes back to "Begin:Running /scripts/init-bottom...done" a second time, M brings up the message:
"Root filesystem check failed. A maintenance shell will now be started"
and then it asks for the root password and gives me a terminal. Everything seems to be there, but apt-get and dpkg both can't do anything as the filesystem is read only.

So I was moving and resizing a ntfs partition and i just touched gparted window and it crashed!! it was about 66% of finishing the operation... Now i guess i have a big mess in my hard drive and i dont know how to start solving it! i am in a ubuntu live cd?
If i open gparted now it shows the same partition table than before resizing and moving.. so i guess now part of my data is in this unallocated space after the sda5 partition.

One of my disks in my computer crashed, it was the one containing /boot and some data partitions. The other system and /home partitions were on a second disk, which is ok.
I was wondering, can I create a new /boot partition, and keep on using the rest of the system? Can I somehow do it with a chroot from a live/installer disk, run grub, and use my system again? I have another disk which I can put in the system, but there is even an unused partition on the disk which is ok (but it is rather big for /boot).

I keep my /boot partition on a usb stick, where i keep the keyfile as well. I already generated the keyfile and added it to the LUKS LVM partition.Right now, on bootup I get a nice GUI to enter my 40 character password which is nice but a little tedious What do i need to modify for the system to automatically unlock the partition with the keyfile that is stored on the /boot partition

When I click on my Vista partition under "Places" in the Fedora menus, I'm asked to enter the root password for mounting the partition. Is there a way to allow any user to mount this particular partition, to avoid the unnecessary input? The partition is not listed in /etc/fstab (fedora 12 for x86_64).

Recently I tried to install Fedora 12 x86_64 to my laptop. I ran the live fedora image from my cooldisk and then pressed "Install to Hard Drive" from live desktop. Then I went forward until I reached the partitioning section. Though I had ~28GB free space in my Harddrive, but it says: "Could not allocate requested partitions: not enough free space on disks." You can see my steps until reaching this problem in these 3
pics:
step1:
step2:
step3:
I captured these steps by using Fedora 12 Live printscreen tool. I tried to install Fedora12 from its non-bootable DVD too, but no difference! So there's only 2 situations:
1. I did something wrong -> install Fedora and use its partitioning tool.
2. There's a bug in Fedora -> confirm that this is a bug and say me an alternative way to install fedora.

I have a usb flash drive and according to sources I found out after the fact that I should have used ext2 instead of ext4 due to the extra write operations.
Is it possible to convert the ext4 root partition to ext2 or do I need to backup, reformat, and restore?

I joined the fedora irc channel and asked how to delete a partition. We actually decided that we could not delete the partition I wanted to delete because it was a root partition. After unmounting the partition, and one other partition with a really long directory name, all of my applications disappeared. I need a safe surefire way to resize a root partition. I don't want to unmount anything because we don't know if we'll be able to mount it again.

Ever since I started using KDE as in 4.2, I have been doing this regularly. When I startup KDE, I open Dolphin and click and mount each partition with root pass. I thought it might be some KDE issue as is the ever developing code and will be fine in future updates. But now I'm in 4.2.1 and it still exists. Upon inquiring fellow users on other distros, I have come to believe this is a *Fedora only* issue now. [URL].

Anyone had any experience with unlocking a LUKS encrypted root partition via ssh? It is ok to leave /boot unencrypted.
There are a few pages from google with the debians variants, archived by putting dropbear into initrd.
I like to do that with my fedora/centos remote servers, but struggle to find any resources specific to it. Anyone has any suggestions and thoughts as to what might be a suitable way forward?

I am trying to extend my / size as its full. Well the volume group is VolGroup00 & logical volume is LogVol00 but when. I run the command vgextend VolGroup00 /dev/sda8. It says volume group not found. Can it be because I have WindowsXP in my /dev/sda1, which falls under same Volgroup??
