 Posted: Wed Mar 19, 2008 10:38 pm Post subject: Error when checking root filesystem on reboot [SOLVED] |
 |
|
Hi,
When I reboot my computer after completing the Gentoo install, when it gets to "Checking root filesystem", I'm given the error "fsck.ext3: No such file or directory while trying to open /dev/sda4". /dev/sda4 is my root partition. It then says "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>". When I try running e2fsck with the alternate superblock, I get the exact same error. Does anyone know how I can fix this?
Thanks in advance for the help!!

Is there any entries in /dev? (-> is udev emerged and running?)
Is /dev/hda4 there but not /dev/sda4? (-> kernel compilation problem, use libata drivers instead of legacy?)

There are no sda* files in /dev, if that's what you mean. The only files in that directory are 'console', 'fd', 'null', 'pts', 'shm', 'stderr', 'stdin', 'stdout', 'tty', and 'tty1'. I don't think it would be /dev/hda4, since this is a new laptop and it uses a SATA drive. As for the drivers to compile into the kernel, I included “Intel PIIX/ICH SATA Support” and “AHCI SATA Support”, as suggested on http://home.earthlink.net/~george164/dv9500t/dv9500t.html (I have a dv9700t, which is the new version of the dv9500t, which that compatibility status page is for).
Also, I forgot to mention that I used the March 17th i686 stage3 archive from funtoo.org, not the official Gentoo stage. |

If | Code: | Device Drivers --->
< > ATA/ATAPI/MFM/RLL support ---> |
is selected your drives may change from /dev/sdxx to /dev/hdxx. |

I pretty sure that is not selected, so I don't think that's the issue. I'll check anyway.
EDIT: Yeah, it's not selected, so that's not the problem. |

| Another strange thing is that when I run /dev/sda* is showing up as mounted to / , even though it's not showing up as a file under /dev . |

| What is the output of cat /proc/partitions ; cat /proc/mounts ; for drive in /dev/[hs]d[a-d] ; do echo ${drive}; echo; sfdisk -l ${drive}; echo; done? This will show us what the kernel knows about your partitions, what filesystems you have mounted, and what sfdisk can determine about the first few drives in the system. |

I had exactly the same problem. I noticed, that udev gave me an error a few lines above the fsck error, saying something about sockets. the problem was a missing option in kernel config:
Networking -> Networking Options -> Unix Domain Sockets
had to be compiled in the kernel. Doing this solved the problem for me.
I hope this helps you |

| Thank you so much! That was it. I would have never guessed a network driver would have been necessary to fix this problem. |

This is not set by default in kernel 2.6.24-gentoo-r4 and is not documented in the gentoo handbook.
Thanks for the fix. |

| Nothing recent is documented in the Gentoo Handbook lol, it hasn't been updated in like 2 years. |

That could be so, but other than the kernel issue, I haven't experienced any other problems with the x86 or amd64 handbooks within the last year. Today, I got a dual XEON Quad compiled and running by command line install via the amd64 handbook in less than 90min. The issue in this post was the only snag I hit.
Cheers, |

Sounds like that's a server, where things haven't changed much...on PCs, particularly laptops, there are a lot of issues which aren't documented well. The main problem is with drivers for various hardware...everything else works amazingly well, though some other things are also out-of-date. These things can be fixed, but it's sometimes hard to find the info on how to fix it. I've had a lot of problems installing Gentoo on my laptop. I'm guessing the devs are more interested in servers than in PCs...same as the kernel devs  |
