when my grub references the UUID for the root= parameter, I get a kernel crash. If I change the root= parameter to /dev/<partition>, grub boots without a problem (f13 64-bit)

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've been away from Fedora for a long time, since FC3/4. I seem to recall that at that time grub in Fedora used the standard drive notation such as /dev/sdax instead of the current UUID. Can anyone tell me why this change was made?
Seems to me that using UUIDs presents severe problems if a drive has to be replaced as the restore media (we all backup, don't we?) would not work without modification. How does one determine trhe UUID of a new drive to change the restore media? Sounds like a chickenand-egg routine. There must be some way which I haven't run accross yet. I do notice through experimentation that the standard notation still works, at least in /etc/fstab.
While saving a file I made a typo and performed the vi command ':w~' instead of ':w!' and I created a root '~' instance in one of my subdirectories. How do I remove this reference without wiping out the entire main /root /~ directory? Do I use unlink()?
View 1 Replies View RelatedSomething 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 .....
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.

View 1 Replies View RelatedI was trying to load up Ubuntu 9.10 on a thumb drive to load look at the files on a computer with a dead disk drive, I couldn�t boot up on the other computer, but that�s another story (yes the drive was marked as bootable)
When I restart my laptop whose diskdrive I used to install Ubuntu onto the USB drive, I get a GRUB error �No such device and can load anything unless I plug back in the USB drive. When it is plugged in, the USB boot is the primary (1st in the list) boot. I tried editing the .lst file on my laptop�s drive but it only has its kernels listed. Anyone know how to make my system quit looking for a USB mounted kernel? Or at least not fail if it can't find one.
I am using Debian lenny (kernel 2.6.26-2-686).
I changed my menu.lst to use
root=UUID=<long uuid string>
instead of the good old
root=/dev/sd...
I did that because, if I boot with a usb drive attached to my computer, sda become sdb and therefor nothing works anymore since my friend Kernel can't mount it's root partition. BTW, it works wonders using the UUIDs. The story darkens each time there is a kernel update, dist-upgrade resets my menu.lst back using the /dev/sd... format. and BANG... no more booting again. I am good to change my menu.lst back each time.
Is there something special I have to do to get grub to use UUID's? I am putting a couple of extra drives into a 9.10 system (default installation) with a SCSI drive for the OS. That SCSI drive was sda when I built the machine but of course gets bumped when I add these other drives. The fstab file contains UUID's. All attempts to boot with the other drives attached fail.

I am new to Fedora. I know my top probably already been posted somewhere but I just could not find it. I just installed Fedora 11. But my root password does not work (I guess was my fault to type wrong in the first place or some type of short term memory lost). I looked at the root password recovery procedure which involves select single user at GRUB page when booting. But for some reasons, Fedora 11 does not boot into GRUB. I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

View 2 Replies View RelatedProblem: 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).
since i dualbooted with wi7, i'm not really sure how to rid myself of this damn thing. i want to just format the whole drive, but windows isn't having much of that.

View 2 Replies View RelatedI updated the kernel to 2.6.35.10-74.fc14.x86_64 and had to reinstall and rebuild the kernel module for my ATi driver as usual, so I edited the kernel arguments at the grub splash screen so that I could boot into single user mode and install the driver (i.e appending the relevant line with '1'). The interesting thing is, the system booted directly into single user mode as root when the system started up. No password was required.
View 6 Replies View RelatedIn backing up my server, I back up my databases with mysqldump. I save that file in /tmp, tar it (w/ gzip), and move it to the backup storage.
However, while phpmyadmin handles .tar.gz, it doesn't like my file, since the .sql file isn't in the root directory of the archive.
That is... when I run tar, it saves the entire directory structure leading up to the file... which is what it's supposed to do.
If I want to import my database back, I need to untar it first, which I don't mind, but I was wondering if there was a way around having to do so...
I am still a newbie at Linux, but have managed to get about 6 different Kubuntu systems up and all running a localhost test web server. I always start out with a server .iso and after installing I add a kubuntu desktop GUI. I have an old laptop that was running 8.04 server w/xubuntu desktop gui and it was running my test web pages through localhost. I got a wild hair and thought it was about time to upgrade to 10.04 server. I always do a complete install and this time I tried lubuntu desktop GUI. I really like lubuntu but for some reason can not get localhost to run. I get a 402 forbidden error. same error with 127.0.0.1 Here is what I get when I run this command

Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.

I am trying to figure out how to get the UUID for some of my external hard drives.the internet revealed a couple of promising leads, this is what I have tried so far:
ls -l /dev/disk/by-uuid -> didn't list the hard discs
blkid -> didn't list the hard discs
lsusb -v -> listed the hard disc but no uuid
A normally formatted usb key is listed with uuid. The external hard discs are fully encrypted by truecrypt(realcrypt). I have been reading not so great things about that itself, but for now I don't have a promising alternative that I can use with windows as well.Any google searches don't seem to cast any new light on this for me,I'd be open to suggestions if there's a better way to get a definite ID for a hard drive... I just need to be able to mount it with realcrypt
I am trying to recover some data on some drives that are in the same LVM. When I upgraded the motherboard, I had complications getting the drives to all load under the LVM, and in the process I made the mistake of formatting one of the drives. The problem now is that the UUID changed on the drive so when I try to mount the LVM it can't find device with a certain UUID. When I try to set the UUID back to the old one it says 'Invalid UUID format'.
I can set it to a UUID generated through 'uuidgen', si I then noticed that the format of that UUID is different than the old one which I'm trying to set it to. Why is that? Is there a way I can get it to change to the old one in the different format?
The old format: yQtrVB-5jCk-vF10-05c2-AcDL-GNn1-ivdxxh
The new format: d5224587-a6cd-4a66-a12b-d7b75eec5871
