Fedora 22 missing space on 6tb ext4

Shown below is an exerpt from my pc's df -T.

Code:

Filesystem      Type      1K-blocks       Used  Available Use% Mounted on

/dev/sdb2       fuseblk  2930134012 2792802128  137331884  96% /run/media/steve/tv_movies_3tb_01
/dev/sdc1       ext4     5814215184  544372776 4976799976  10% /run/media/steve/tv_movies_6tb_01

The 3tb hard disk was formatted in Windows 7 as NTFS. The 6tb hard disk was formatted in a Fedora 22 terminal by the following commands:

su

lsblk (to determine device name of new hard disk) : sdc ... 8:48 0 5.5T 0 disk

parted /dev/sdc
(parted command) mklabel gpt
(parted command) mkpart primary ext4 1MiB 100%
(parted command) quit

exit

The arithmetic makes sense for the 3tb hard disk: 2930gb - 2792gb =~ 137gb.
The arithmetic does NOT make sense for the 6tb hard disk: 5814gb - 544gb =~ 5270gb. Only 4976gb are reported as available. What happened to the other 294gb that should still be available on the 6tb hard disk?

Actually it does make sense - have a look at the "similar threads" at the bottom of this page.
For a data disk, feel free to set the reserved to zero.

SOLVED. Thanks syg00.

One of the threads below has the url of: http://www.linuxquestions.org/questi...0-10-a-852494/

tune2fs -l accounted for 283gb of the missing 294gb. Presumably, the other 11gb, which is trivial to me, is used for ext4 maintenance (e.g. journaling).

CORRECTION

My math was off. tune2fs -l accounted for 293+ gb from the missing (approximately) 294 gb.
