However, be very, ah, *cautious* about trying any ext4 options beyond 
the RH defaults. I tried creating some with extents and other 
non-default options yesterday and it immediately triggered kernel panics 
when I tried to mount the resulting file systems. On the other side, 
I've been running default ext4 options on CentOS5 on some machines for 
years now with no hiccups at all.
