Ubuntu :: Boot Failure - Can Not Find Root Partition No Uuid
Mar 5, 2010
I posted this first to thread 'Boot problem - "Gave up waiting for root device.", (initramfs)' then realized that I should start a new thread because the problem is not the same. On boot the splash goes black and nothing happens, On a recovery boot it drops into shell BusyBox and messages indicate that the root partition cannot be found. After booting from CD Gparted GUI partition information shows no label or ssid for the root partition sda2. The data for the root partition appears to be there. how to fix this? My /home, swap, and / are on separate partitions formatted ext3. I have a recent backup only for my data. I would like to avoid having to rebuild my system from scratch.

Recently, I had to switch harddrives on one of my servers due to the need for hardware.
However, when I switched back to the original harddrive I got a surprise : Instead of booting normally in OpenSuse 11.3, it booted in the grub shell.
I did a root ( hd0,1) but when I attempted the setup cmd it failed. Thinking that I probably was a configuration error ( nothing was changed - the drive had spent some time in a nice anti static bag ) I booted using a USB key.
To my surprise I got a message stating that parted couldn't read the other partitions ( boot and swap ) and hence I would not be able to edit then. Fortunately, the data partition seemed OK so I can backup the data.
Preferbly, I would like to be able to restore my original system.

First time trying anything like this. I'm running a Abit NF7 with a silicon image 3112 that's support was broken in 2.6.35. I get a kernel panic when VFS can't find the root partition, I can't remember the exact line (can't log it, root isn't mounted yet) but it says something like sata1: link down (sstatus 0 scontrol 0). I think there might be a more telling error message before, but it flies by too fast to see or capture with my camera video recorder.
There's a patch that reverts back to when there was a delay in /drivers/ata/libata-sff.c in the function ata_sff_tf_load, by calling ata_wait_idle(ap) which fixes the issue for some people but not my system. I don't know anything about what I'm doing, but I thought I'd go through and add printk's in each function in sata_sil and see how far the device was initialized. I did this but they all happen early in the boot that flies by. Is there any way to add a pause like the "more" command? [URL]

We had a drive failure on /dev/sda. Everything 'except' boot was on raid5 across sda, sdb, sdc, sdd. I know how to repartition a new drive and rebuild the raid etc, but I don't know how to regenerate the files that reside on the boot partition. I really don't want to re-install as we have lot of custom code and software that may depend on our current libraries and build environment.

I'm a long time Linux user. Finally got around to upgrading my Fedora 11 system to Fedora 12 by using the 'preupgrade' tool. The upgrade appeared to go well (downloaded packages, rebooted into installer, etc). However, now that the upgrade is complete, I'm unable to boot my system.
Here's my configuration:
/dev/sda (80Gb)
200Mb /boot partition (ext3)
52Gb / partition (ext4 - managed as logical volume)
2Gb swap partition (managed as logical volume)
20Gb /spare partition (ext3 - managed as logical volume) .....
All worked fine under Fedora 11 for the last few months. Grub now presents me with 'Fedora' and 'Windows XP' boot options. The /boot/grub/menu.lst file is essentially the same as it was for Fedora 11, except for the different kernel versions, etc. The boot sequence shows the Fedora bubble (??) and gets about 80% full when the screen goes black and the message displayed is:
No root device found
Boot has failed, sleeping forever
If I boot Windows, all works fine.
Am able to boot using a SystemRescueCD disk. The disks all look okay and I can mount/modify all partitions, etc. The grub menu.lst file read as follows (sorry, typed in, not copied):
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.32.11-99.fc12.i686.PAE)
root (hd0,0) .....

I am able to retrieve data off a RAID5 array. History: My system disk was partitioned to 10 gigs and over time was filled up to 100% locking me out of the GUI (I am a casual user). Now that I am relegated to the CLI, I need help to see if rebuilding the array and keeping the data intact is possible. I have three sata hard drives in the array and now it appears during the boot process, it fails and can't find the array.
I did the following:
mdadm -D /dev/md0
and here's some of the output:
State: active, FAILED, Not Started
And out of three drives, it states that two have failed. I find this hard to believe as I have had no issues until my system disk was full. A coworker today helped me find some files to delete and now have the system disk down to 97%/8.8 gigs yet I can still not enter the GUI due to the array issue.
Out of the three discs, here are the results (taken also from mdadm -D /dev/md0):
Number Major Minor RAID device STATE
0 8 1 0 active sync /dev/sda1
1 0 0 1 removed
2 0 0 2 removed
Sorry for providing so little, but I am in (Repair Filesystem) mode and only have local access to the machine meaning all outputs will need to be retyped.
I am able to do anything to the box as its only purpose was media storage and serving.

Say I need to do: find / -name somefile.txt
And say root partition / is mounted on /dev/sda5; however, let's say I also have 250GB partitions (/dev/sda6, /dev/sda7) mounted in /media - AND another location that I cannot currently remember. Say, also, that I know the file I'm looking for is on /dev/sda5.
Obviously, the above command will also descend in /media and that other directory which represent the big partitions, wasting time in looking for the file in the wrong place.
Is there a way to instruct find (or other command) to search only / on /dev/sda5, and NOT to descend to directories if they are on different partitions ?

After installing another OS on second drive, UUID for swap on my main system was missing. In other words there is no appropriate symlink in /dev/disk/. I've tried to create it manually, but it dissappears again after rebooting. Temporarily i solved this problem by adding in /etc/fstab direct address to swap device. The question is how to restore UUID for swap partition correctly?
Code:
sudo blkid /dev/sda6
/dev/sda6: TYPE="swap"
/dev/sda6 is swap partition.
Also i've tried to use tune2fs:

I am running Wheezy as my main OS in the first drive in my desktop. I use the 2nd drive for data. I am trying to add another OS to multiboot. When I ran grub-update in Wheezy, I am getting device letter for the root device instead of UUID in grub.cfg, in the os-prober section. Like this
Code: Select allsearch --no-floppy --fs-uuid --set=root 6ee49a8e-a619-49c7-9f66-51a5ca9a48cc
linux /boot/vmlinuz-316-x86_64 root=/dev/sdb3
initrd /boot/initramfs-316-x86_64.img
In the same file, UUID was used for the existing kernels.
Code: Select alllinux /boot/vmlinuz-3.2.0-4-686-pae root=UUID=c2eecf02-d427-4f2e-9fd0-9db61256cbac ro quiet
echo 'Loading initial ramdisk ...'
initrd /boot/initrd.img-3.2.0-4-686-pae
How can I get UUID instead of /dev/sdb3 for the 2nd OS?

I have a Netbook Remix install on an SD card that won't boot. Grub2 in the recovery mode shows it fails finding the root files by using UUID. It's my first Grub2 install and I'm not sure how to go about debugging it. The machine boots the same version from a USB stick.

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?

I rsync the filesystem where I have my server to another HD. Now, when I try to boot I'm dropped at initramfs with an error. It looks like it's still looking for the root in the previous HD even tough I already changed /etc/fstab. It says it can't find the device with a certain UUID, and that UUID is from the previous HD.
Here's the full details: I'm running Ubuntu server 10.04 It has 2 hard drives. Every night it backups one to another with the command
Code:
rsync --archive --one-file-system --hard-links --numeric-ids --delete
I moved the HD where I have the backup to another machine and rsynced them with the same command I then changed /etc/fstab in the new machine. I also installed Grub on it When I boot in the new machine I get a error about not finding root. It says that a device is not present. It says the UUID of the device is looking for, and it's the UUID of the first HD.
I thought I only had to change /et/fstab but seems I am wrong.

I am very much new to Linux programming. My question is Is there any way to read UUID of a device or partition in linux programatically. Is there any c/c++ API for user-space applications. I found some commands "sudo vol_id --uuid /dev/sda1", "sudo blkid", "ls -l /dev/disk/by-uuid/". But all are commands which we need to run in terminal. But I need to achieve this from a c/c++ program. (FYI: I need to read uuid of root filesystem ("/") where Linux has been installed.)

I have, as I have in the past, copy/pasted a partition using gparted to get a working OS to another place.
I have always done this in the past to a different drive. Never paid much attention to the UUID.
This time I did it on the same drive. The partitions have the same UUID. This is not a good thing.
The copied OS boots and mounts fine as I edited the fstab to go by /dev/sdxy (where x is the drive and y the partition). My grub uses a custom menu using symbolic menu entries so it goes by the partition definition instead of UUID too.
I would really like to change the UUID on that partition.

Someone (not me) recently installed some new distros on my HD. It seems that during the installation my swap partition was reformatted and a new UUID was assigned to it. I have the following questions:
1. I know that I have to change the swap partition UUID in /etc/fstab and /boot/grub/menu.lst of the affected distros. Is there anything else that needs to be changed?
2. I presume a similar change has to be made to the Grub 2 configuration, for those distros that use Grub 2. I have no experience using Grub 2 so how do I make the change or where can I find instructions to do it?

I dual boot Ubuntu 9.10 and Windows XP. I booted into Ubuntu 9.10 and upgraded to 10.4 and upon reboot Ubuntu could not find the boot partition, it reported only /dev. I restarted my pc and and selected Windows and, fortunately, I was able to boot into that OS.

I've had Ubuntu for quite some time, but recently I got my hands on a copy of a Windows 7 Upgrade disk, and thought that I would like to dual boot between Windows and Ubuntu. I wiped Ubuntu from it's partition because I know that Windows is picky and needs everything to be clean to be installed. Then I proceeded to install Windows 7 using the upgrade disk only to find that the product key to activate Windows wasn't valid. This was because I tried to clean install Windows 7 instead of upgrading. Then I reinstalled Ubuntu 10.04 on my computer and was able to dual boot between Ubuntu and Windows. After reading online, I discovered that all I had to do was reinstall Windows once I was running Windows for the product key to be valid. Now windows is running great on my computer, but I am unable to find the Ubuntu partition to boot into it. Every time I turn on my computer it goes straight to windows and I don't even have the option to boot into Ubuntu even though it is still on my computer.

I would like to dual boot Ubuntu and Windows 7. I have Ubuntu 9.10 Live CD and Windows 7 Pro Live CD. Ubuntu is installed but Windows 7 isn`t. I have gparted installed. I found the following directions within Ubuntu documentation.
Master Boot Record backup and re-replacement
Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code:
Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with)
Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1
Install windows
Boot into a LiveCD
Mount your root partition in the LiveCD
Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1
Restart and Ubuntu will boot
Setup grub to boot windows
I don't want to backup the MBR and restore as listed. I would rather use the Ubuntu Live CD to reinstall the GRUB.
How do I overwrite the MBR?
Do I use gparted and change the partition?
Do I create an NTFS partition as listed above?
Or what do I need to otherwise do to boot the Windows 7 Live CD so that it will install?

what's the difference (if any) between choosing to boot from the MBR, the root partition or enabling neither? Referring to: pic23-MBR switch.png - Windows Live Would one be better for dual boots for example? (Using Vista too)

Problem: I have installed two Ubuntu servers, 10.04 32-bit and 10.10 64-bit, in a multi-boot environment (also have FDOS and WinXPsp3). The 64-bit will not boot because grub can't find the UUID for the disk with the 64-bit system.
Brief Background: Installed 10.04 LTS two months ago with no problems. 10.04 is in a primary partition on hda with FDOS.
Installed 10.10 (64-bit) in a new primary partition on the same hd. The install seemed to go ok, but the MBR and the fs on the 10.04 were corrupted; could not boot. Restored drive, and rebuilt grub.
Installed 10.10 on separate hd (hdb). In grub step all OS's were recognized so I pointed the grub to hda. Grub failed to boot.
Rebuilt grub from 10.04 on hda. All systems recognized but 10.10 will not boot because it says it cannot locate the UUID specified.
Compared the grub.cfg for both systems, the UUID specified for hdb is the same. Also, when I mount the drive for 10.10 on the 10.04 system the drive UUID is consistent.
I know I must be missing some thing, but I know not what. Have searched and can't find any clues. All other OS's boot ok.
Hardware: AMD64 4GB, 2 internal IDE drives (hda and hdb), 1 internal SATA (hdc WinXP), various USB and Firewire Drives (no bootable systems).

From one day to the other my system stopped booting properly. Since I (finally) fixed it, I wanted to share my solution. It runs on a fakeraid pair of SSD's of 60 GB each (actually a single Revodrive device, but it shows up as two devices). When Ubuntu 10.10 boots, I'm dropped to a shell.During boot, when I removed "silent splash" from the kernel's command line, I got these messages:
Code:
[ 4.960240] scsi 6:0:0:0: Direct-Access ATA OCZ-REVODRIVE 1.20 PQ: 0 ANSI: 5
[ 4.960425] sd 6:0:0:0: [sdg] 117231408 512-byte logical blocks: (60.0 GB/55.8 GiB)
[cod]....
I doubt that this is what was needed (as I had that already when it didn't work, but I might be required in addition to installing dmraid)
# update-initramfs -a
After installing this, the problem was solved!! This is strange since I don't recall uninstalling this package or changing anything important, for that matter (perhaps did apt-get upgrade, but that's about it!). [URL]

My disk partitions are as following:
Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x58b258b2
[Code]....
There already exist an os XP before my installing of ubuntu.When I installed my ubuntu 9.10, I selected to install grub2 on the logical partition sda7. But when I typed command sudo dd if=/dev/sda7 of=mbr bs=512 count=1, I found that the file mbr was eerily full of zero bytes. How does this happen? Or grub2 can't be installed on a logical partition? But it works very well along with win7 rather than XP.

I just did a fresh install of 11.4 and I LOVE IT!!! One of the little issues I am having though, is that there is no login screen. No matter what settings I change it still auto-logs me in.
I am using GRUB and the Boot Loader Location has both "Boot from MBR" and "Boot from Root Partition". Is this right? I would think that I should just boot from the MBR.

Something wrong regarding grub2 (on 9.10). Yesterday everything worked fine and has done for several months. I didn't mess with anything yet when I booted from grub today it informed me that my UUID doesn't exist and that it's given up waiting for root device. I should also mention that it no longer does the 3 second count down either (not sure if thats significant). I can boot into my other linux and windows without issue. This only seems to affect all the ubuntu boot option. This is all way beyond me but I've searched around and tried the fix where you add all_generic_ide to the boot command but that didn't work. I also worked out how to check the UUID but the number look alright.
grub.cfg and blkid below:
# DO NOT EDIT THIS FILE
# It is automatically generated by /usr/sbin/grub-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub
### BEGIN /etc/grub.d/00_header ###
if [ -s /boot/grub/grubenv ]; then
have_grubenv=true
load_env
fi .....
