df -h is giving weird output
 

i have a a problem with my RH7.2 machine ... when i df -h i get this

Filesystem Size Used Avail Use% Mounted on
/dev/hda2 690M 658M 0 100% /
/dev/hda1 29M 2.7M 24M 10% /boot
none 30M 0 30M 0% /dev/shm

[root@localhost local]# rpm -i ~ ftp/upload/ntop-2.1.3-0.i386.rpm
installing package ntop-2.1.3-0 needs 9Mb on the / filesystem

well the output is really wak..apparently iv only got no space on /

has anyone seen this before or is there something im doing wrong?? well there is more than 9Mb !!!! meh!

thanks once again lq ppl

The problem is that some part of the filesystem is reserved to root, that's usualy 10%. You can change that value with tune2fs as root:

# tune2fs -m <value> /dev/hda2

You can re-allocate space as vladkrack says, but that is still just a temporary solution. You also have a very large amount of space allocated to the /boot partition -- way more than you need, unless you're heavy into kernel playing.

But all that aside, you have a very small amount of Linux space as compared to what you are trying to use that space for. I would strongly suggest finding a larger drive, or cutting out the excess -- if there were any excess to cut ;) .
