Disk usage for /home partition?

Hi,

Was looking over my disk usage and trying to figure out where I lost about 3GB of space. My root partition looks fine as I did a full install, but the disk usage for my /home partition doesn't add up. Just wondering why the discrepancy:

bash-3.1$ df -h

Filesystem - Size - Used - Avail - Use% - Mounted on
/dev/hda2 - 7.6G - 4.1G - 3.2G - 57% - /
/dev/hda3 - 65G - 824M - 61G - 2% - /home

Thanks in advance.

Try

Code:

 du -Hs /home

995M /home

(I'm downloading a cd image so it increased since my first post)

I'm a little confused, you seem to have a ton of free space. What 3GB are you talking about?

Read the tune2fs man page if you're using ext3, and look for the -m option.

pdw_hu makes a good point. ext3 filesystems reserve 5% of the space on a given partition so that root can login successfully even if the filesystem gets full. On a 65 Gb partition, 5% is 3.25 Gb, which seems to add up to your missing volume. However, 3.25 Gb is a lot to reserve, so if you REALLY want all (or some) of that space left, tune2fs should be able to free it up for daily use.

That makes perfect sense now, T3slider. Thanks for the great explanation and thanks to everyone for the input. It's not like I'm short of disk space, but this little mystery was kinda bothering me.
