[RAID] GParted resizing has corrupted a partition

Hi All,

I was running Karmic 64bit, and wanted to install a 32 bit version.
I've resized a partition with GParted, shrank it with 20GB. It was previously mounted to /home.

All partitions are ext4, and I'm on RAID0 using my Intel's ICH9R.

After shrinking and installing the 32 bit karmic on the new partition, the old /home partition isn't accessible.

fsck.ext4 /dev/mapper/isw_bahdiiijae_Volume06 (the problematic partition) returned:

The filesystem size (according to the superblock) is 46026217 blocks
The physical size of the device is 40905498 blocks
Either the superblock or the partition table is likely to be corrupt!

I know that the physical size is "right", since it's after the shrink. The superblocks see the data before the shrink.

I have done many tryings and google searches, and nothing helped.
I didn't manage getting testdisk, fsck, fsck.ext4, resize2fs nor e2fsck to work.
Also, all my tries to find how to change the size of the disk as the filesystem thinks it is, have failed.

Please, help me save my dear /home!
