    Exclamation no init found, Try passing init=bootarg and then some

    I am having a problem simular to apperrently alot of people in here however none of the solutions anyone else provides seem to work. When I boot I get several error messages:

    mount: mounting /dev/mapper/ubuntu-root on /root failed: Invalid argument
    mount: mounting /dev on /root/dev failed: No such file or directory
    mount: mounting /sys on /root/sys failed: No such file or directory
    mount: mounting /proc on /root/proc failed: No such file or directory
    Target filesystem doesn't have /sbin/init.
    No init found. Try passing init= bootrag


    Then when I have run a live cd and tried following several different advice I get the following:

    sudo mkdir /media/root
    sudo mount /dev/sda1 /media/root

    mount: unknown filesystem type 'LVM2_member' (I have tried installing lvm2 and this command still doesn't work)

    sudo fdisk /dev/sda1

    The number of cylinders for this disk is set to 36449.
    There is nothing wrong with that, but this is larger than 1024,
    and could in certain setups cause problems with:
    1) software that runs at boot time (e.g., old versions of LILO)
    2) booting and partitioning software from other OSs
    (e.g., DOS FDISK, OS/2 FDISK)
    (It then comes up to a command prompt....I have been running this server for about a month before now without problems)

    sudo e2fsck /dev/sda1

    e2fsck 1.41.4 (27-Jan-2009)
    e2fsck: Superblock invalid , trying backup blocks...
    e2fsck: Bad magic number in super-block while trying to open /dev/sda1

    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:
    efsck2 -b 8193 <device>

    sudo e2fsck -b 8193 /dev/sda1

    e2fsck 1.41.4 (27-Jan-2009)
    e2fsck: Superblock invalid , trying backup blocks...
    e2fsck: Bad magic number in super-block while trying to open /dev/sda1

    efsck2 -b 8193 <device>


    I am obviously in way over my head here because a) I am really new to ubuntu and b) I have no idea what in the world a super block is.

    Someone please help... if you need anymore info please let me know (I am going to need step by step direction).

    My hard disk died at the end, so all the problems came from bad sectors, etc.

    Good luck!

    This post led me to the answer:

    http://ubuntuforums.org/showpost.php...05&postcount=2

    I ran a live CD, opened terminal, and typed in "sudo fsck /dev/sda7" (where my ubuntu partition was located)

    Thanks man
    after booting through live DVD i did
    sudo e2fsck -C0 -p -f -v /dev/sda1

    then it asked for a manual fsck i did
    fsck /dev/sda1 and now it is ok.

    Any way i have decided to backup the Disk and throw this one

    I know the thread is a month dead, but I thought perhaps it was better to keep it here than start a new one. I get this every time I reboot. I boot into the liveCD and "fix" it by scanning with gparted, then boot to the hard drive, everything works like a charm till I reboot and have to do it again. Could someone point out what may be the actual CAUSE that I can look into rather than just how to work around it?? Thanks.

    [edit=add] The issue is on 10.04 and the partition in question is ext4, if wither of those points are relevant. [/edit]
