When I run
df -h I get the following
Filesystem Size Used Avail Use% Mounted on /dev/sda3 809G 753G 14G 99% /
But Size - Used is not even close to Avail (809-753 = 56 and it shows 14)
How is that possible? How much space do I really have left?

Usually there is some "reserved" space for superuser (sic), and then there is the fs overhead (i-node tables, etc). Depends on the filesystem.
ext2/3/4 has a default reserve of 5% for uid0 (
depending on the usage-type (
-T) i-node space is pre-allocated - see
I'd say the 14G are really available, but there may be 40G of reserve and say 100MB of i-nodes, which would pretty much add up. #ymmw
