Debian system won't boot due to corrupt file system

  • 772

I am having this problem with my server when I boot. I'm trying the fsck /dev/sda1 by logging into maintenance mode which i get the option to do when it boots. Check the screen shot.

It's so far found 9 inconsistencies and fixed them. Can anyone give me any advice? is there a recovery mode for debian?

Debian GNU/Linux 5.0 \n \l uname -r: 2.6.26-2-amd64

Proc info: http://pastebin.com/1gVtNLxM

debian boot

    Is there a recovery mode for debian?

    Well you have the maintenance mode, just type in your root password. If you cannot run fsck, or it cannot clean up your filesystem, then you need to simply restore from your backups.

    Can anyone give me any advice?

    Do exactly what it told you to do. Drop to the shell and run fsck. If a fsck can't clean the filesystem, and you don't already have a good backup, then I would try to extract/export anything off that disk that you can ASAP.

  2. In addition to the above answer I would suggest to run fsck like this, to avoid tons of keypresses:

    fsck -y /dev/sda1

    From the manual:

    -y     For  some  filesystem-specific  checkers, the -y option will cause the fs-specific fsck to always attempt to fix any
       detected filesystem corruption automatically. Sometimes an expert may be able to do better driving the fsck manually.

    I don't remember ever breaking a filesystem doing that.

    By the way, in debian it's not turned on by default, but you can do so and avoid most of these pesky maintenance mode prompts that require physical presence. In file /etc/default/rcS set:

    FSCKFIX=yes
