Nope,
the system 'reserves' 10%.  This is so
that if the disk gets 'full', root
can log in and clean up or do what ever.
I believe this 'reserve' can be configured
when you set the disk up.

Hi all:

I know I ought to know the right answers, but I'm juggling a few too many
variables that need to be filled in.  If there's a quick 'splanation, I'd
love to hear it.

First you have to understand that most of my hardware knowledge is of the
Gizzinta type (this squarish sort of pluggy thing gizzinta the back of the
HDD, that tiny pluggy thing gizzinta the back of the CDRom and the other end
gizzinta the sound card...).

Yesterday I popped an 80GB IDE drive into my favourite Linux box, which
should hold me until June.  I hope.  After convincing the BIOS that YES,
Virginia, there is a properly pinned drive connected to that controller (20
minutes of aggravation whilst fidgeting with a brand-new and unfamiliar
BIOS), the machine finally saw the drive at the proper size.  You wouldn't
believe some of the answers it came up with before hitting the right number.

I then restarted Linux (6.2, btw) who let me fdisk and mkfs to my heart's
content.  fdisk seemed to think it was an 80G drive and set it up that way.
Later, when I did "df -hl" it showed up as 73G free with nothing written to
the drive but superblocks and tables.

Question:  Do the basic mechanics of the ext2 file system really take up
almost 10% of the available space?  7GB seems awfully high for overhead.  Or
is it just me?  Or is it in the way that df reports the space?

Bill
