Hello all,

I am using Debian (Woody) and I just installed a 160GB Maxtor harddrive.
Partitioned and formattted without any problems using parted.

I copied a large number of medium sized (3~10 MB) MP3 files to one of the
ext2FS partitions.

When I run df, I get the following result:

Filesystem 1k blocks Used Available
/dev/hdc3 128076316 4453272 117117124

If I substract the number used blocks (4453272) of available blocks
(128076316 ) I get 123623044 as the result. However, according to df, the
available space is 117117124. A 6 GB difference! I wonder if this partition
too big, or if I should use another filesystem or ... ?

The partition is mounted on /opt

Any help would be greatly appreceated!

Best regards,
Kees

man mke2fs:

-m reserved-blocks-percentage
Specify the percentage of the filesystem blocks reserved
for the super-user. This value defaults to 5%

You can change the value using tune2fs.

I'm guessing you're doing all this as a regular user. Try doing it as
the super user and see what it says then. 6M is about 5% out of 128M,
which is normally the amount of space reserved for root alone to use.
