odd problem with large ext4 file system

[Jerry Feldman]

I hope that you are doing your fsck (assume fsck.ext4) on an unmounted
file system. If you allow fsck to fix a mounted file system, you are
asking for trouble. The ONLY time fsck should be run on a mounted file
system is on root, and when it is mounted readonly.

Basically, I think that the Fedora 12 version of ext4 has been well
tested (read some prior Jarod Wilson posts).

I also assume that you are using either LVM or RAID0 striping.
