The filesystem size (according to the superblock) is 104388 blocks
The physical size of the device is 103408 blocks
Either the superblock or the partition table is likely to be corrupt!

/boot contains a file system with errors, check forced.

/boot: 36/26104 files (2.8% non contiguous), 12201/104388 blocks
I would say this is (fairly) conclusive proof that the filesystem is
really truncated, and RHEL 6 is just ignoring that hard fact. Note
that the code paths used by ext4 kernel and e2fsck (ie. e2fsprogs) are
quite different, and both think the filesystem is longer than the
containing device.
Sorry :-(
