Debian :: Fsck.ext3: Unable To Resolve 'UUID=theUUID'

Jun 24, 2011

Upon booting my LVM wheezy setup, I get

fsck.ext3: Unable to resolve 'UUID=theUUID'
where "theUUID" (without the quotes) is the UUID

I believe this is caused by me trying to get lvm to use the external /boot because when I had unmounted the external /boot, it was creating a /boot in root. So, I booted a live cd and mounted the external /boot where /boot in the root volume is supposed to be. Basically, I think the problem is that I need to make my /boot (which is the only ext3 partition in the entire system and I want it that way) "relate itself" to the lvm root so that it boots into the system. As mentioned earlier, in the live CD, I made the external /boot mount itself in the root's /boot but I don't know how to tell the system to do this on its own while booting without my assistance. I chrooted from the live cd which involved a lot of tedious stuff but basically the important stuff I did were:

grub-install /dev/sdb
update-grub
update-initramfs -u

P.S.I get the issue in the Subject of this topic by telling tune2fs to mark the external /boot, lvm / and /home partitions as "dirty."

Debian Hardware :: Boot Warning Fsck.ext4: Unable To Resolve UUIDs?

May 15, 2011

I have $ uname -a
Linux kub 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64 GNU/Linux

Most of the time when I boot my PC I get an error about fsck.ext4: Unable to resolve... I don't know why it's happening.

The problem is happening with my external drive that has 3 partitions:
/dev/sdc1
/dev/sdc3
/dev/sdc2

About 90% of the time I boot I do get the error. Sometimes after getting the error I can login and the external drive (/dev/sdc) is already mounted:
$ df -H
Filesystem             Size   Used  Avail Use% Mounted on
/dev/sda2               15G   8.0G   5.8G  58% /
tmpfs                  1.9G      0   1.9G   0% /lib/init/rw
udev                   1.9G   246k   1.9G   1% /dev
tmpfs                  1.9G   738k   1.9G   1% /dev/shm
code....

The UUID's in the error file match the output of the command blkid. And the UID's of blkid match the fstab UUID's. I don't know what to do at this point.

Ubuntu :: Unable To Fsck Ext4?

Jan 24, 2011

Seems like I misplaced this topic. Should have been in general help. Sorry! Any moderator feel free to move this topic. As I was creating a swap partition, something went wrong and I ended creating a much bigger file which consumed all my empty space. Ubuntu stopped working and now I can't seem to fsck / mount my disk. Currently I'm on a live cd. fsck will give:

Code:
e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Device or resource busy while trying to open /dev/sda2
Filesystem mounted or opened exclusively by another program?
However, the file system is not mounted.

General :: Boot Loader Capable Of Ext4 And Of UUID's?

Mar 2, 2010

I've got the latest version of Ubuntu on my machine.My Linux partition is ext4, so I need to use a Linux boot loader capable of booting from ext4.Also, I want to be able to use the UUID of my partition instead of specifying "/dev/sda3".Right now I'm using the Grub2 (or whatever the f*** it's called) that comes with Ubuntu. It's the ugliest boot loader you'll ever see, the configuration file is disgusting.So with that in mind, I'd like to change boot loader.Lilo would be OK but I can't seem to get it to boot from ext4.The older version of Grub was fine too but again I don't think it can boot from ext4.

Fedora :: Corrupt Ext4 LVM - Fsck?

Dec 3, 2009

I go to bed and my computer is fine and working. I come home from work, no signs of a power outage, and my computer has errors regarding a corrupt disk. Drops to Cmd prompt. My problem is that I want to do the proper recovery on it, and my googling doesn't seem to help. All I see is stuff about how FAST fsck is, but no one wants to talk about how to use it. Besides, I better check with people before I mess everything up.

I have the FC12 install disk I used loaded up now, at the cmd prompt. I have my system mounted, an EXT4 LVM. Do I unmount and then run fsdk.ext4 -fp /dev/mapper/vg_mysys-lv_home ? (lv_home is the one reported as corrupt during boot)

OpenSUSE Install :: Fsck - Not Needed With Ext4 Filesystems?

Apr 17, 2010

My openSUSE 11.2 system has periodic running of fsck disabled for ext4 filesystems (Maximum mount count = -1, Check interval = 0). What is the reason for this? Is it because fsck is not necessary on a periodic basis with ext4, and only necessary when errors are detected? Or is it because fsck has problems working on ext4 filesystems?

The ext3 filesystems do have it set (Maximum mount count = 500, Check interval = 5184000 (2 months)). I would like to know why fsck is not set to be activated for ext4.

General :: ATI Driver (Unable To Resolve Execstack) Ubuntu

Feb 12, 2010

The proprietary drivers that came with my ubuntu 9.04 installation are not doing their job. My cpu is managing my graphics (compiz-fusion, and a 3d obj running in the background) and I alway have a core of my phenom processor close to 100. I have an ATI 4870 gpu with 2gb internal ram on the card. Also, recordmydesktop, electric sheep, and any other simple graphics all lag. 3d games on the other hand have no problem. I decided I would try the driver I downloaded from AMD. I removed the proprietary driver, ran...

Code:
sudo sh ./ati-driver-installer-10-1-x86.x86_64.run --buildpkg Ubuntu/jaunty
and I get

Code:
Created directory fglrx-install.lPNHYh
Verifying archive integrity... All good.
Uncompressing ATI Proprietary Linux Driver-8.69 .....
/bin/sh: execstack: not found
make: *** [binary-install/xorg-driver-fglrx] Error 127
dpkg-buildpackage: failure: debian/rules binary gave error exit status 2

How to make the proprietary driver work better I'm all for that to.

Ubuntu :: Adding A CD-ROM Drive - Unable To Find UUID

May 2, 2010

Just added a DVD drive to a machine which had no drive before. When I boot I get the error about being unable to find the root drive by its UUID. If I unplug the DVD drive it boots as normal.

I'm guessing the root drive is getting a new name i.e /dev/sda2 instead of sda1 and thus a new UUID. How can I add the drive and fix the UUID issue in grub?

Ubuntu :: Unable To Boot Due To Changed UUID In RAID Array

May 9, 2010

I'm running 64bit Lucid. I've recently had a severe problem with my softraid (5) array, and have had to recreate the array to fix it. However this now means that something is up with GRUB/initramfs, and booting times out while waiting for the root device (md0) to be ready. /boot is on a normal partition, not the raid array itself. A friend of mine has rebuilt my initramfs file with the new UUID, but now I get the message: 'Kernel panic not syncing: VFS: unable to mount root fs on unknown-block (9,0)'.So my question is either how do I sort this error, OR how do I rebuild initramfs/grub in a way that will boot?

Ubuntu :: Unable To Dd Drive And Retain UUID And Mdadm Superblock

May 18, 2011

I have an mdadm linear array of 4 500GB drives. One of them had a few bad sectors, so I've dd'ed it to a new one (conv=noerror), and tried to start my array. Mdadm refuses, saying, "mdadm: /dev/md4 assembled from 3 drives - not enough to start the array."I had diffed different samples from different positions on the source and the mirror drive and confirmed they were identical. Checking the superblocks confirms three old drives still having their superblocks as expected, while the newly mirrored one has,

daniel@lnxsrv:~$ sudo mdadm --misc --examine /dev/sdf1
mdadm: No md superblock detected on /dev/sdf1.
- and,
daniel@lnxsrv:~$ sudo blkid /dev/sdf1

[code]....

As before. The mirror apparently has no uuid, but the original does. To confirm my sanity, I did,

daniel@lnxsrv:~$ sudo dd bs=1M count=50 if=/dev/sdc of=./sdc && sudo dd bs=1M count=50 if=/dev/sdd of=./sdd && sudo diff -s sdc sdd
50+0 records in

[code]...

How can the uuid not be the same when bit-for-bit from the very first byte of the drive, covering MFT etc., these two drives are identical according to diff?

Ubuntu :: Fsck Usr Fails And Unable To Repair?

Dec 2, 2010

I am travelling so would really appreciate a few tips that should hopefully get my pc running again. (I have internet access via a kiosk, and can burn a disk if necessary, but the smaller the download the better)I have a few ideas that with some help I should be able to fix the partition.1. Is there a simple way to use use grub, to mount all partitions read only and not to fsck them so I can logon in normal user and sudo and hopefully fix the parition?or 2. Download a small version of ubuntu or something that I can burn to CD (my machine cannot boot from usb) so that I can repair the machine.3. Download the ubuntu installer (alternative) and try and reinstall the necesary usr partition?

General :: Migrated From Ext3-disk To A Ext4 Disk - Warning: Unable To Open An Initial Console

Feb 4, 2010

OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:

mount --bind /dev /dest/dev
chroot /dest

modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?

General :: Proftpd Fails On Boot Saying "MasqueradeAddress: Unable To Resolve Rowilson.dyndns.org"

Mar 21, 2011

I have proftpd set up on my linux home server. As I have a dynamic IP at home, I am using DynDns.org to provide a hostname for me. I have told proftpd to use this address as the MasqueradeAddress, to allow passive FTP connections through my NAT router.

However, whenever I boot my server, proftpd fails to start saying it cannot resolve this address. I assume this is due to the boot order, as something network or DNS related hasn't started up by then and it can't find the address. How should I deal with this problem? Can I get proftpd to do its checking for the address later on? Or can I change the startup order so that proftpd is started as the final item in the boot sequence?

Ubuntu :: Unable To Mount Ext4 Partition

Still a novice in Ubuntu (Karmic Koala). I'm trying to mount an ext4 20GB partition of my hard drive so that i can use it to store data, i want it to appear on my desktop as well as on places, as far as i know this is achieved by mounting the partition in /media. At my first attempt i used the following commands. (i named the partition ondskapt)

Code:
sudo mkdir /ondskapt
sudo gedit /etc/fstab
in this document i added the following at the end:
/dev/sda4 /ondskapt ext4 defauts 0 0

Ubuntu Installation :: Unable To Format To Ext4

Aug 6, 2010

i recently bought a new pair of rams, after i installed them (removed the old ones) ubuntu started lagging and all my applications started normaly, after half a minute they didn't respond for 2 minutes and then back to normal again. So i decided to delete the ubuntu partition and re-install ubuntu. I begin the installation normaly but it stucks at 5% where the partitioning takes place.

I also tried gparted to create an ext3 and ext4 partitions but i had the same problem on both tries. I believe it is a ram problem, should i go and replace them, or there is a possible solution without replacing them? (Also run the memtest 86+ for 4 hours and there were no errors).

Ubuntu :: Unable To Mount Ext4 External Hard Drive

Jul 5, 2010

I wanted to make a clone of my drive, so I tried the ole sudo dd if=/dev/sda1 of=/dev/sdg1 trick, but first I formatted the drive to the Ext4 format. I wish I would have understood that format a little more before I decided to format it that way. Now I can't access my drive at all. I read almost everything on the net about manually mounting it, but almost everything was in Fat, NTFS, or Ext3/2 format. I even read the Ubuntu documentation. I don't know if it's because my drive is in Ext4 format, or if I'm just not doing something right.

As you can see in the following picture, it recognizes the drive, yet I am unable to mount it. I am trying to access the 160 GB drive. I even tried to see if Windows would recognize it. No go. Today while lurking in the Ubuntu Forums I found a way to make a live .iso of my system (which I think is awesome). So now I want to reformat my drive and use it as storage once again. I think I will restore it to NTFS. I thought that the Ext4 format would work better in Linux (which I was wrong), but now I need Windows to recognize it as well, and it needs to be able to store files bigger than 4 GB (unless you have a suggestion on what to format it as).

Ubuntu Installation :: Unable To Boot From Removable Ext4 Drive

Oct 12, 2010

I recently downloaded Ubuntu 10.10 and installed it onto a 250gb removable disk using a 240gb ext4 partition and a 10gb swap space.

I am using a Sony VAIO (VPCF115FM) and it would appear that my BIOS is very limited as to bootup options. I can only choose internal HDD/external device/network/CD Drive. I cannot check whether or not my BIOS is able to recognize the external ext4 (but from experiences so far it would seem that it cannot)

After much tinkering i got my internal windows 7 to recognize the drive as ext3 (Used ext2 volume manager to add a registry entry for the drive). However, I need to unplug and replug in the drive for it to be recognized, if i leave it plugged in from booting it shows up as unrecognized.

Summary: I would like to be able to boot up Ubuntu off this external drive, but as of now it would appear that my BIOS is unable to recognize the drive. Windows can recognize it as ext3, and I can access contents of the ubuntu partition from windows.

how I could get this working that would be fantastic, i've tried formatting the drive to other filesystems (ext3,ext2,XFS) but none of them would work either, so any information would be sweet

General :: Edit UUID Using The Dd Command?

Oct 9, 2010

I have gone over the thread "Learn The DD Command Revised" (It was Fantastic) in the search for a solution to my query.

I have seen posted elsewhere that this code is supposed to be able to change the UUID number of NTFS partitions (useful when multi-booting with Grub2 and cloning partitions). Here is the code:

Code:
sudo dd if=/dev/urandom bs=80 count=1 | xxd -l 80 -c 8 | tail -1 | xxd -r - /dev/sda1
This is assuming that I want to change the UUID on the 1st partition on the 1st hard drive >>>sda1<<<
If I was trying to modify the 2nd partition on the 1st hard drive it would be >>>sda2<<<

[Code].....

NOTE: I was doing this while booting from Ubuntu's Live CD version 10.04.1 LTS (In case that is a factor)
