 Posted: Mon Jan 07, 2008 2:54 am Post subject: [SOLVED]Can't boot fresh gentoo install |
 |
|
I've run a stage3 install from the minimal CD and followed the handbook to the letter (this also isn't my first time with Gentoo--I had a working install a few months ago but had to wipe the drive to put on a windows image--so I know it shouldn't be a hardware incompatibility problem) but when I boot I'm getting an error when it checks /...
| Code: |
...
Mounting devpts at /dev/pts ... [ ok ]
Checking root filesystem ...
fsck.ext3: No such file or directory while trying to open /dev/sda5 /dev/sda:
The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
Filesystem couldn't be fixed :( [!!]
Give the root password for maintenance
(or type Control-D to continue):
|
Running e2fsck doesn't seem on other blocks doesn't seem to do anything and, furthermore, /dev/sda5 is non-existent (or any other /dev/sda* for that matter). The filesystem is mounted RO but none of the other file systems are mounted. My /etc/fstab is as follows
| Code: |
/dev/sda2 /boot ext2 defaults,noatime 1 2
/dev/sda5 / ext3 noatime 0 1
/dev/sda6 /usr ext3 noatime 0 2
/dev/sda7 /home ext3 noatime 0 2
/dev/sda8 /var ext3 noatime 0 2
/dev/cdrom /mnt/cdrom ext3 noauto,ro 0 0
|
(/dev/sda1 is a Vista Ultimate install)
I'm pretty sure none of the filesystems are actually corrupted as I've loaded up the installation env and run fsck on /dev/sda* and they're all clean, but I'm at a loss as to why it is none of my partitions are showing up in /dev, yet it's still mounting my root partition...could it possibly be some sort of problem with GRUB? I've attached the grub.conf in any case.
| Code: |
default 0
timeout 30
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
title=Gentoo Linux 2.6.23-r3
root (hd0,1)
kernel /boot/kernel-2.6.23-gentoo-r3 root=/dev/hda5
title=Gentoo Linux 2.6.23-r3 (rescue)
root (hd0,1)
kernel /boot/kernel-2.6.23-gentoo-r3 root=/dev/hda5 init=/bin/bb
title=Vista
rootnoverify (hd0,0)

I'm rather tired at this point, so if I forgot anything I can provide whatever other info might be needed. Thanks in advance to anyone who can shed some light on the subject.

| I would guess that you have forgotten to include support for ext2 and ext3 when you built your kernel. Chroot into your system from the install cd and make sure you have both selected to be included directly in the kernel and not as modules. Then rebuild and install the kernel again. |

Thought of that already. I originally built in ext2 and ext3 support, but when this started happening I rebuilt the kernel with everything ext2/3 related and I'm still having the same issue. I didn't think to include this last night, but the original problem I had was an error about being unable to mount the root from an NFS, which I think was caused by my SATA drivers being modules (confused me for the longest time...had the intel sata driver built in, but didn't notice the SATA (prod) and PATA (experimental), which houses the intel stat driver, set as a module :/), which I fixed by including it in the kernel...could it be that I missed a necessary SATA driver? It's an intel ich6, so I added the intel sata support and the ahci sata driver as well.
Anyway, here's an lspci dump if it helps at all (it's a ~3yo IBM Thinkpad T43p) and the full names of the SATA drivers I have built into the kernel

|
| Code: |
<*> Serial ATA (prod) and Parallel ATA (experimental) drivers -->
<*> AHCI SATA support
<*> Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support
|
...I would assume that the Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support should cover what I need, but I'm not entirely sure, and there aren't any other Intel SATA drivers there (the only other intel stuff on the list would be Intel PATA MPIIX support and Intel PATA old PIIX support) |

If you use /dev/sda5 in /etc/fstab, shouldn't it be the same with the grub options? Or did I get something terribly wrong?

You were likely using a < 2.6.22(3?) kernel before and got bitten now that you use a 2.6.23 kernel. The 2.6.23 kernel includes a feature that will rename disks attached to a few common sata controllers as /dev/hdX instead of /dev/sdX. You need to disable the CONFIG_IDE entirely to get your disks to be seen as /dev/sdX again.

Just out of curiosity, is there a list of the SATA controllers that undergo this change with the 2.6.23 kernel? Was there a reason for this change?

Well, that's a pain in the ass. Changing by fstab to /dev/hd* instead of /sd* fixed my problems. Yeah, I think I was using a 2.6.19 kernel..where is this CONFIG_IDE that I need to disable? |

I don't think anything is getting renamed. It is simply a case of the older IDE driver loading before the newer libata driver has a chance to attach to the device.
In general, it is a bad idea to have the kernel configured with more than 1 driver trying to support the same piece of hardware. |

| Actually, it is getting renamed. For some reason my partitions have been renamed as /dev/hda*...strange, but whatever. It's working for now with fstab set up referencing them as /dev/hda* instead of /dev/sda*, so I'll screw around little by little with it and work out the kinks as I go. |

You are right in that the IDE device gets to control the SATA controller before the sata driver is loaded, but as I understand it the increased support of devices by the generic IDE driver is what makes it bond to at least the Intel, AMD and nVidia sata controllers, unlike what happened before the 2.6.22 or 2.6.23 kernel.
I started noticing this from some comments here about the renaming, which at the time I didn't understood, and then it hit me on my AMD64.

Hey I am having the same problem as above ^^
Can someone please let me know how to use the livecd to go back and change my fstab? |

What you basically need to do it chroot back into your environment, and you do that by booting the minimal installation disc and doing the following:
| Code: |
mount -t FSTYPE /dev/ROOT /mnt/gentoo
mount -t FSTYPE /dev/BOOT /mnt/gentoo/boot
swapon /dev/SWAP
mount -t proc /proc /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
env-update && source /etc/profile
export PS1="(chroot) $PS1"
|
You replace the items in CAPS with your actual information. Therefore, FSTYPE would be either ext2, ext3, et cetera based on your system, and BOOT & ROOT would be /dev/whatever_partition. If you need further assistance, please just ask.

I'd be more than happy to help you with the problems (if I can), but you might want to start your own thread about them, as that will keep the boards a little more tidy.

| So I've been pulling away bits of IDE support in the kernel and trying to get this to recognize my drives as /dev/sda* instead of /dev/hda*, but nothing is working. Does anyone have any insight on how it is I'm supposed to get my drives back to being /dev/sda*? |

The best way is to remove all IDE support, and use only the newer libata drivers instead.
Your kernel .config should look like this.
| Code: | # CONFIG_IDE is not set
CONFIG_ATA=y |

K, I've done that, but now I'm back to square one. I can't boot again, even after modifying my fstab. The only thing I modified about the kernel was to comment out CONFIG_IDE...All my SATA drivers are still intact, etc. but when I boot I'm getting:
| Code: |
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Insert root floppy and press ENTER
|
This is the original message I got when I accidentally had my SATA drivers set as modules--however, all my SATA drivers are now compiled into the kernel.
...so, any ideas? |

Get to your kernel editor:
| Code: |
cd /usr/src/linux
make menuconfig
|
Go to this section:
File systems --> Network file systems -->
Remove support for NFS File System Support, and NFS Server Support
Recompile the kernel, copy it over to your boot directory, and reboot.

Found the problem. I modified my fstab, but in the process I forgot to change my grub.conf

No problem; glad you found the solution. If you could kindly put [SOLVED] in the thread title, it would be appreciated. Also, if you need further help, please just ask.
