Not surprising; I think you had already covered that possibility with
fstat(1). It's vaguely possible that the space is used in large files
that are "covered" by the dev filesystem mounted in named's chroot, but
I think it's more likely you have some filesystem corruption.

Have you tried an fsck(8)? As usual, you would want good backups first,
and then rebooting to single-user mode so you can fsck the filesystem
without it being mounted.

Good luck.
