BUG in EXT3-fs: fragsize 1024 != blocksize 4096 (unsupported)

Hi everyone!

Since three days ago mi PC with Fedora 9 started to do random resets.

I started to change the BIOS configuration and one this changes leaved the screen
black. Unfortunately I pressed the reset button thinking that didn't boot but the next time (after
leave the BIOS configuration like before) the system didn't boot.

It showed me this message: "EXT3-fs: fragsize 1024 != blocksize 4096 (unsupported)". http://forums.fedoraforum.org/attach...0&d=1268739264

Researching I could get info from the root fs with dumpe2fs:

# losetup -r -o 196608 /dev/loop0 /dev/hda2

# dumpe2fs /dev/loop0

The disk has two partitions:

kdemar@kademar:~$ fdisk -l

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xb838b838

Device Boot Start End Blocks Id System
/dev/hda1 * 1 25 200781 83 Linux
/dev/hda2 26 9729 77947380 8e Linux LVM


hda1 is for boot and hda2/lvm/ext3 with the OS and data. ext3 is a ournal filesystem, so i think this is a BUG.

My BIG question is how can I repair this lvm/ext3 volume without loose data?
