General :: Pausing Kernel During Boot - VFS Cannot Find Root Partition

Sep 28, 2010

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]

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.

General :: Find/search Root Partition ONLY?

Jun 11, 2010

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 ?

Slackware :: Pausing During Boot To Check Sda4?

Jan 16, 2011

While booting Slackware 13.1 it stops to check sda4 It says something about discrepancies. This started today after leaving the system up overnight. The system was suspended and wouldn't respond. I ended up have to do a hard reboot. The system seems to be working fine, but it does this every time I start Linux. The sda4 partition is Windows XP. XP also is working fine. While Linux is checking sda4 there is a statement that I need to run fsck without options. When I ran fsck I got the following message.

root@b-bhome:~# fsck
fsck from util-linux-ng 2.17.2

OpenSUSE Install :: Find Old Kernel / But It Still Won't Boot

Sep 23, 2010

My laptop threw a wobbly recently (same time as kernel update?) I have got it to find the old kernel, but it still won't boot.It's a 11.3 install, dual-booted with XP. The /boot partition is in the root partition - sda7. Why is it trying to mount sda7 as swap? (not in fstab like that)

OpenSUSE Install :: Failure Reading Root Partition During Boot?

Nov 19, 2010

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.

Ubuntu Installation :: 9.10 And Win7 Dual Boot And Root Partition

May 11, 2010

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?

Ubuntu :: Unable To Find The Partition To Boot Into It

Jun 24, 2010

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.

General :: Can't Find Boot Device - Error "Unable To Determine Major/minor Number Of Root Device"

Mar 17, 2011

I just compiled my first own kernel (I'm using Arch Linux), following the tutorial on the german site. Now I tried to boot it, I ended up failing with this message: Code: Waiting 10 seconds for device /dev/sda1 ... Root device '/dev/sda1' doesn't exist, Attempting to create it. ERROR: Unable to determine major/minor number of root device '/dev/sda1' Here is the important part of my menu.lst:

[Code]....

I simply copy&pasted the Arch-entry, i.e. I also had the disk by uuid there. The failure message was the same, just the root device name was the different name Also, at first I did not have the initrd line in my menu.lst (as written in my tutorial that I may not need it). In this case I had this error message:

OpenSUSE Install :: Using GRUB And The Boot Loader Location Has Both "Boot From MBR" And "Boot From Root Partition"?

May 19, 2011

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.

Ubuntu Installation :: Boot Fails: Can't Find Root Device + Drop To Shell

Dec 27, 2010

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]

Ubuntu :: Can't Find Boot Loader On Logical Partition

Oct 27, 2010

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.

Ubuntu Installation :: GRUB Can't Find Menu.lst / Can't Boot Kernel

Feb 10, 2010

I seem to have determined a few other things about my "only gets as far as a GRUB command line" problem:To recap, sda3 (GRUB hd0,2) is the main Linux partition; sda9 (GRUB hd0,8) is the boot partition.GRUB is 0.92.Installation was from an 8.04LTS live CD (at least, that's what the envelope says it is)/"/boot/grub" (i.e., "/grub" on sd9/hd0,8) contains a "menu.lst" file. I modified it (had to do a "sudo gedit" from a command line!) to (1) comment out the line that hides the boot menu, (2) change the timeout from 3 seconds to 90, and (3) add a menu line based on my succesful manual IPL of DOS.

It still boots to a GRUB command line. If I do a "configfile /grub/menu.lst," a boot menu comes up. DOS will successfully IPL, but Linux still gets a "no setup signature found," (ditto for "recovery mode"), which suggests either a bad kernel, or a kernel that's too big for the GRUB to handle.Why would it be finding its way to grub, but not finding the boot menu file?Why would the live CD come up just fine, yet the GRUB and kernel it installs fail?

Debian :: Boot Fails With Kernel Panic After Moving To A New Partition

May 16, 2010

Because I am using one of the new WD disks I am trying to aling my root partition with the real sectors, as described here: [url]

So I copied all files to a temp location, deleted my partition (/dev/sda3), recreated it a few cylinders later (same name) and copied the files to the newly created partition. I updated UUIDs in grub's configuration as suggested in this thread:[url]

But now it fails to boot with the following error:

Code:

I checked the filesystem on this partition and its fine. I tried to recreate the initramfs from Knoppix:

Code:

But it didn't change anything.

How can I either fix it or install a different kernel on this drive so I could boot into it and re-install my default kernels?

Fedora Installation :: Identify Partition Location - Getting The FEDORA Bootloader To Find The PREUPGRADE Kernel

May 29, 2010

Going from Fedora 12 to 13. Got to the point where I have to reboot to install, system reboots to 12. This is a triple boot system with Open Suse and Mint, and the grub2 bootloader from Mint is the bootloader for the whole shebang. In the "how to use preupgrade" instructions there's a line that says "dentify the drive and partition of your Fedora /boot folder." How? If that sounds odd, consider that in my set up "computer" shows 4 partitions (and with just three operating systems..?). I can mount them, but have a problem telling which sytem is Fedora, Suse or Mint. And getting the FEDORA bootloader to find the PREUPGRADE kernel ... Momma said there'd be days like this.

cat /etc/fstab just returned /dev/sda1 on /boot. I installed Fedora first, before Suse or Mint, so being on the first drive or partition sounds right, but the multiple drives throws me, and "just guessing" doesn't seem like the way to go.

Fedora Installation :: Kernel Update Fails Due To 10MB Boot Partition

Feb 23, 2010

Finally updates are broken - I've been able to use my upgraded F12 system for some time, faithfully keeping up with f10, then f11. Just yesterday it finally broke:

Test Transaction Errors: installing package kernel-2.6.31.12-174.2.22.fc12.i686 needs 10MB on the /boot filesystem

It would appear that the most recent kernel update has broken the 10MB barrier initially set by the version I first installed (for the boot partition). Needless to say, I have quite an investment in this machine, and of course no time to back it all up and do a fresh F12 install. I am hoping someone out there can give me a bulletproof way to steal some space and expand the boot partition...
