htree - incompatible feature enabled

[Timothy Jedlicka bonzopad]

I was trying to resize a Gentoo disk.  Apparently Gentoo's version of make2fs 
uses the Htree(?) feature which is apparently incompatible with parted.  So 
this documents what I did to fix it. (thanks to edcjones from gentoo for the 
solution).

To fix I ran 
: tune2fs -O ^dir_index /dev/hda4
Then ran (answering "y" to the INDEX_FL questions
: e2fsck -f -y /dev/hda4

e2fsck 1.30-WIP (30-Sep-2002)
Pass 1: Checking inodes, blocks, and sizes
Inode 720915 has INDEX_FL flag set on filesystem without htree support.
Clear HTree index? yes

Inode 884740 has INDEX_FL flag set on filesystem without htree support.
Clear HTree index? yes
...

This at least got me past the "incompatible feature" problem.  Now it doesn't 
like the layout of my filesystem which I'm continuing to work on.
