Hmm .... truely strange .... just for grins try:

	# cp /[ext3-partition]/database /[reiserfs-partition/database
	# od -x /[ext3-partition]/database > /tmp/hex.ext3
	# od -x /[reiserfs-partition/database > /tmp/hex.reiser
	# diff /tmp/hex.ext3 /tmp/hex.reiser

and if the diff doesn't report anything, then

        # cp /[reiserfs-partition/database /[ext3-partition]/database2
        # od -x /[ext3-partition]/database2 > /tmp/hex.ext3-2
        # diff /tmp/hex.ext3 /tmp/hex.ext3-2

and if this diff doesn't report anything, then

	# lsattr /[reiserfs-partition/database /[ext3-partition]/database2
	# ls -l /[reiserfs-partition/database /[ext3-partition]/database2

and if these are reasonable, then it's likely the data base routines
are sensitive to particular UID/GID or keep track of dates/sizes internal
to the database looking for corruption/tampering.
