 Posted: Tue Jan 07, 2003 9:28 pm Post subject: Gentoo Kernel Panic |
 |
|
Hi I just got done installing Gentoo about an hour ago I restarted my computer just as the manual I printed from the site said to do, but after I restarted I get this message: read_super_block: can't find a reiserfs filesystem on (dev03:03, block 64, size 1024) read_super_block: can't find a reiserfs filesystem on (dev03:03, block  Kernel_Panic: VFS: unable to mount root fs on 03:03 before I restarted my computer my fstab looked like this:
/dev/hda1 /boot ext3 noauto,noatime
/dev/hda3 / ext3 noatime
/dev/hda2 none swap sw
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
proc /proc proc defaults
Also I compiled EXT3 support into the kernel, reiserfs support into the kernel (dunno why  ), and... EXT2 support. Is there anyway I could fix this problem? please help installing gentoo took forever id hate to start over  |

It seems to me that the kernel you compiled and that you are trying to boot from only has a driver for ReiserFS while your disks are Ext3. Did you compile in support for Ext3 in the kernel or as a module? In order to boot, you need the filesystem compiled into the kernel.
Try to boot the system again with your LiveCD and mount the drives as you did during install, then chroot as during install and reconfigure your kernel to support Ext3 also.

I compiled EXT3 not as a module, ok so I am in
Linux right now (replying to your message with lynx)
and I tryed to do as you said with the liveCD here is what I did.
mkdir /mnt/gentoo
mount /dev/hda3 /mnt/gentoo
I then got a message saying: mount: you must specify the filesystem type
I then did
mkdir /mnt/gentoo/boot
mount /dev/hda1 /mnt/gentoo/boot
after I did that I did not recieve a message like I did above...?
I then did cd /mnt/gentoo and extracted the stage1 tbz2 file with tar -xvjpf then did
mount -o bind /proc /mnt/gentoo/proc blah... rest is in the manual.
Then finally chroot /mnt/gentoo /bin/bash then env-update then source /etc/profile
Ok after I did that I went to /usr/src/linux and there it said that no directory could be found?.. do i have to download the package gentoo-sources again?
or am I doin this whole thing completly wrong? |

Ok I tryed mount -t ext3 /dev/hda3 and it said that the HD didn't have
a EXT3 file system on it I then tryed -t reiserfs and got the same error I posted above...
After I got these two errors I decided id go into CFDISK it says
EXT3 file system for /dev/hda1 (boot), swap for /dev/hda2, and just Linux for /dev/hda3 (/root)
guess ill just format and install again  |

I'm also getting this problem with 1.4-rc2.
Following the standard install procedure, I made hda1 (/boot) and hda3 (/) reiserfs. Set up grub - it recognized my reiserfs boot partition. I figured all is well. Rebooted.
Recieved an error 17 in stage1.5 when booting grub (unsupported fs). Being that I was using grub-0.92, I figured I'd try upgrading to the latest version of grub (as it's supposed to fix this problem).
Booted off the CD. Tried to mount /dev/hda3 (my root partition)...no luck. Trying to mount the partition with a typical 'mount /dev/hda3 /mnt/gentoo' command only returns "you must specify a filesystem type'. Actually specifying a filesystem type (mount -t reiserfs /dev/hda3 /mnt/gentoo' returns some read_super_block errors.
I also was unable to unmount /mnt/gentoo after the install; I'm suspecting that this is the cause of the problems - corruption must be occuring in /dev/hda3. This idea is further supported by the fact that I _CAN_ mount /dev/hda1 (/boot partition) without any errors.
Maybe it's time to file a bug report.... |

read_super_block: can't find reiserfs system on ...
Kernel Panic: VFS: can't mount root file system

I had the same problem and got my partitions out of order in etc/fstab
In the install doc, the partitions order on the partitioning page is:
boot
swap
root
in the etc/fstab it's
boot
root
swap
When I double checked the partition order, I realized in fstab I was mounting root on my swap partition causing the above error. 
This may not be your particular problem, but if it is (or someone else's), this post might help.
Thanks. |

Hi
I have just the same problem, knowing that I know that everything was booting fine ubtil I finish emerging xfree 4.3.0 and KDE.
| Code: | read_super_block: can't find reiserfs system on ...
read_super_block: can't find reiserfs system on ...
Kernel Panic: VFS: can't mount root file system
|
The output of cfdisk says :
| Code: | hda1 boot Primary Linux ext3
hda2 Primary Linux swap
hda3 Primary Linux
|
I did not succeed in mounting /dev/hda3 with the live CD.
Is there any solution to get back a working drive ?
| Code: | # mount /dev/hda3 /mnt/gentoo
mount: you must specify the filesystem type
|
Thanks. |

I don't recall the parameter that tells it the type is reiserfs. its -t and then some indicator (hopefully documented in the mount man pages).
There is also special instructions in the install guide about using reiserfs (something about notails => the parameter is -o notails).
Sorry for the scanty info. Hopefully someone can fill in the specifics.
Good luck!
