resize2fs on LVM on MD raid on Fedora Core 3 - inode table conflicts in fsck

[Stephen Warren <swarren@xxxxxxxxxxxxx>]

Hi.

I'm attempting to setup a box here to be a file-server for all my data. 
I'm attempting to resize an ext3 partition to demonstrate this 
capability to myself before fully committing to this system as the 
primary data storage. I'm having some problems resizing an ext3 
filesystem after I've resized the underlying logical volume. Following 
the ext3 resize, fsck spits out lots of errors like:

Pass 1: Checking inodes, blocks, and sizes
Group 49's inode table at 1605636 conflicts with some other fs block.
Relocate<y>? no

I believe that I'm following the correct procedure for resizing the 
filesystem. Any pointers greatly appreciated. Thanks.
