Ahh, good --- I was about to ask what version of FC you were using now,
and what version you had used to create the fs initially.  e2fsprogs
used to have a bug interacting with some versions of the kernel when
querying the device size.  As a workaround on those old versions, you
could use "mke2fs -b 4096" to force it to use a 4k blocksize when
calculating the device size, and avoid the overflow.  

Newer e2fsprogs should always get it right; please do let me know if you
still find problems in that area, I think I got them all fixed for FC3
and FC4.

Cheers,
 Stephen
