Hi Rodrigo,

Ok, so I understand why the free space is not equal to : "available - used"

But in this case why when I turned the minfree space at 1% with tunefs there is no change ??
This point I don't understand

About manufacturer the volume make 400Go, and appears like 393Go :)

Thank you all

Alain
