Linux Real Time Issues-5

File system check failed. Won't boot.


Here, try this one.

Bootup from Live CD, than go to terminal and:

sudo blkid

it will return something like:

/dev/sda5: UUID="eae4ddca-b9b1-48d4-abba-e26bc44027a4" TYPE="ext4"
/dev/sda6: UUID="7ff08df9-693a-4841-a459-b934c672a821" TYPE="swap"

(This is mine result, sda5 is my ubuntu partition).

Ok

copy its UUID

Than open on your filesystem file /etc/fstab

Search for your sda and paste UUID there. (replace wrong UUID number)

root file system check failed

Been having a few issues. Basically I'm locked of my laptop.

It says: Root filesystem check failed
A maintenance shell will now be started
CONTROL-D will terminate this shell and reboot the system
root@charley-laptop:~# 


It looks like you need to run fsck on your root partition. You can do this from a live CD (make sure the partition is not mounted) or you can do it from the maintenance shell if you remount the root partition read only.

In either case just make sure the root partition is not mounted read/write.

Code:

fsck /dev/sdX

where X is the partition for /. You can do a trail run with the -N switch.



It 'n' to not ignore the error.

Run fsck again but try using a backup superblock instead of the main one. That one may be corrupted.

Run the trail run with the -N switch to see what it says.

---------------------------------------------------------------------------------------------
So you using GDM. It sounds like it may be corrupted. What happens if you drop to a virtual terminal (ctrl + alt + f1) and restart GDM ?

Code:

sudo service gdm restart

or

Code:

sudo /etc/init.d/gdm restart

------------------------------------------------------------------------------------------------------

When I boot at this moment I get the following message during the boot,
when the file system of sda4 (the new installation) is being checked.

* File system check failed.
A log is being saved in /var/log/fsck/checkfs
if that location is writable.
please repair the file system manually.

* A maintenance shell will now be started.

CONTROL-D will terminate this shell and resume system boot.

When I press "CONTROL-D" or "Exit" or "Reboot" the system boots up
and I can use her, but I prefer to solve this so I can boot the normal way.

he log file (/var/log/fsck/checkfs) contains

I hope this will help to find a solution.

ok, this line "# /dev/hda3
UUID=88202516-902e-4382-9291-680daed83138 /media/hda3 ext3 defaults 0 2" has the possibly bad uuid entry, please post the output of this command

Code:

sudo vol_id --uuid /dev/hda3
