 Posted: Fri Feb 08, 2008 3:33 am Post subject: fsck.ext3: No such file or directory |
 |
|
Hello,
I recently installed Gentoo on my new laptop. After booting normally once, I noticed I didn't have tmpfs (I use temerge) support in kernel (2.6.24), I rebuilt it, and rebooted without any other changes, only to get this error message:
| Quote: | Checking root filesystem ...
fsck.ext3: No such file or directory while trying to open /dev/sda4
/dev/sda4:
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): |
Searching the forum only got me this thread:
https://forums.gentoo.org/viewtopic-t-641789.html
where the problem was simply the kernel named the SATA drive hda, but if I do the changes mentioned there, it only gives me a error message sooner, saying that it can't find /dev/hda4, so that doesn't seem to be the problem. Any other ideas?
My hard drive is set up like:
/dev/sda1 swap
/dev/sda2 Windows
/dev/sda3 ext2, boot
/dev/sda4 ext3, root
I've installed Gentoo on other computers before and never had this problem. Any ideas? Is there anything else I should mention about the computer?
Thanks.

There certainly isn't a drive /dev/sda. Make sure your fstab and bootloader configuration are OK. |

Oops, thats a misprint, I'll edit it. It should say /dev/sda4 twice.
My fstab:
| Quote: | # /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda3 /boot ext2 noauto,noatime 1 2
/dev/sda4 / ext3 noatime 0 1
/dev/sda1 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,ro 0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for

# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)

| Boot a LiveCD and run file -s /dev/[hs]d[a-f][1-9]. That will show us what /usr/bin/file thinks of each of your partitions. |

origin415,
Give the root password, as the error message says and run to see the filesystem types.
Your root is still read only so to fix /etc/fstab, if thats the issue, you need to do | Code: | | mount -o rw,remount / |
to get root to be read/write.

df -T prints out
| Code: |

rootfs rootfs 40283116 4336576 33900264 12% /

udev tmpfs 10240 0 10240 0% /dev |
the file command prints
| Code: |

/dev/sda2: x86 boot sector, code offset 0x52, OEM-ID "NTFS ", sectors/cluster 8, reserved sectors 0, Media descriptor 0xf8, heads 240, hidden sectors 86093280, dos < 4.0 BootSector (0x80)
/dev/sda3: Linux rev 1.0 ext2 filesystem data
/dev/sda4: Linux rev 1.0 ext3 filesystem data (large files) |
I'll try compiling a 2.6.23 kernel next (though I'd love to have tickless for my laptop) |

With kernel 2.6.23-r6, it booted up fine.
Guess I should wait until 2.6.24 stabalizes? Or else I misconfigured it. |

Guys, same problem here: (was trying to do a reinstall of gentoo, God knows why ). Just have one extra line of code output there as well:
extfs_check_if_mount: No such file or directory while determining whether /dev/sda5 is mounted.
Please help me, i do not what I did. When I last installed gentoo using the same kernel everything seemed fine. Am using 2.6.23-r6.

/dev/sda3 none swap sw 0 0
/dev/cdrom /mnt/cdrom audo noauto,ro 0 0

Please, someone please tell me, what the hell is wrong here. I desperately need to boot into my gentoo installation.

rahulthewall3000,
| Code: | /dev/sda5 / ext3 defaults 0 1
/dev/sda6 /home ext3 defaults 0 1 |
the last digit (1) in the fstab tells the order that partitions should be fscked in.
Journalled file systesms do not need to be checked - thats why you have a journal.
The file system will replay the journal if needed, without fsck.
Read man fstab - you should not have two entries with a 1 in this field. I have mine set to 0, which means never check.

This is my new fstab,
/dev/sda5 / ext3 defaults,errors=remount-ro 0 1
/dev/sda6 /home ext3 defaults 0 2
/dev/sda3 none swap sw 0 0
/dev/hdc /mnt/dvd-rw udef,iso9660 noauto,rw,users 0 0
/dev/sda1 /mnt/XP ntfs-3g users 0 0
However, now I get this error.
Checking root filesystem ...
fsck.ext3: No such file or directory while trying to open /dev/sda5
/dev/sda5:
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>

Sorry for not updating on that! What should I do now?

rahulthewall3000,
Why do you want to run fsck or a journelled filesystem at all ?
I suspect the message means that udev has not yet created the /dev entry for root.

All right, I will see what happens if I edit my fstab and then reboot.

All of these issues were related to the incorrect kernel configuration for device drivers, once that was fixed, everything was fine. I can not run checkfs on the disks if I want to.
