Error resizing ext3 partition |

First, I had a primary ext3 partition from 156.885 to 25007.431 megabytes,
and an extended one containing an other logical ext3 partition. I got rid of
the extended one (including the logical ext3 one), so I won't mention it
furthermore. I just rm'ed it.
Then I tried increasing the size of the first ext3 partition to include the
space gained by deleting the extended one. I did it while it was mounted. I
know it's stupid, but I didn't have a floppy drive to boot from. I didn't
even try to boot as single user.
I had the hope that parted would tell me that I can't resize a partition that
is currently mounted read-write. It didn't. Maybe it's supposed to be able to
do it, but it failed. It took a while, and at the end, it said: "block
relocator should have relocated 6324739".
Since then, the system was not able to find any file. I was in a KDE session,
and I could not launch anything. In the terminal, df, du, and fdisk were not
found. Parted was found, I don't know why (in-memory cache?).
I rm'ed the partition to recreate it with the original size, but it didn't
work either. I rm'ed and recreated it a few times back and forth from
original to new size (156.885 to 58644.140).
cortex:~# parted /dev/hdb print
Disk geometry for /dev/hdb: 0.000-58644.140 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.031 23.532 primary ext2 boot
3 23.533 156.884 primary linux-swap
2 156.885 25007.431 primary ext2
So, in short, the resized partition, as it was right after the resize,
started at 156.885 and finished at 58644.140.
Attached is a dumpe2fs of /dev/hdb both for the original and resized
partitions (I rm'ed and mkpart'ed to dump both).
I'd be interested in recovering the data, if possible ;) I did a backup of
the important data before resizing, but it's a pain to re-install the whole
distro...
Thanks for your help,
