When I did it, I just used fdisk to delete the partition, and then to re-create a new one of the larger size.  The new one must start at the exact same cylinder as the old one did, but can have more cylinders.  It's a little scary because of the messages about data loss, but it worked fine for me. 

 

To the best of my knowledge, fdisk doesn't touch any other part of the disk other than the partition table, so provided the new partition is larger than the old, and begins at the same position as the old, everything works fine.

 

One precaution I took -- and I recommend you do the same.  I first backed up the entire logical volume, by creating another one of the same size and using dd to copy the content.  That way, if did anything stupid and broke my windows filesystem, I'd have been able to recreate it.

 

Derek.
