ext3: No journal on filesystem on dm-0
Hi Linuxers,
I am a newbie here and loggin this facilities regularly.
Recently my PC experience a power trip, my system could not boot up after restarting.
I did the following :
- Boot up with "linux rescue" using installation disk FC3
- In a shell, run "lvm vgchange --ignorelockingfailure -P -a y"
- since / parition is not mountable, I run "mknod /dev/dm-0 b 253 0"
- fsck -y /dev/dm-0, it took a long time but it clean now
- mount /dev/dm-0 /tmpRoot
- found out that there were NOTHING! except the lost+found directory which contains many files with a "#" prefix
- Restart the system but still could not boot up
One of the message says "ext3: No journal on filesystem on dm-0"
I am in a fix and what should I do now ?
Anyone could shed some light would be greatly appreciated!
regards
Chow

extlinux(1) General Commands Manual extlinux(1)
NAME
extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem
SYNOPSIS
extlinux [options] directory
DESCRIPTION
EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem. It works the same way as SYSLINUX, with a few slight
modifications. It is intended to simplify first-time installation of Linux, and for creation of rescue and other special-purpose boot
disks.
The installer is designed to be run on a mounted directory. For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
the following command:
extlinux --install /mnt
OPTIONS
-H, --heads=#
Force the number of heads.
-i, --install
Install over the current bootsector.
-O, --clear-once
Clear the boot-once command.
-o, --once=command
Execute a command once upon boot.
-r, --raid
Fall back to the next device on boot failure.
--reset-adv
Reset auxiliary data.
-S, --sectors=#
Force the number of sectors per track.
-U, --update
Updates a previous EXTLINUX installation.
-z, --zip
Force zipdrive geometry (-H 64 -S 32).
BUGS
I would appreciate hearing of any problems you have with SYSLINUX. I would also like to hear from you if you have successfully used SYS-
LINUX, especially if you are using it for a distribution.
If you are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems
reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems.
There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To join, send a message to
majordomo@linux.kernel.org with the line:
