Modify partition sizes

[jandafields]

How can I move space from the /home partition to the /usr partition? I get daily notifications that it is over 80% full.

I am using CentOS 4.9

Filesystem            Size  Used Avail Use% Mounted on
/dev/hda5             3.0G  1.4G  1.6G  47% /
/dev/hda1              99M  9.6M   85M  11% /boot
/dev/hda8              49G   25G   22G  54% /home
none                  490M     0  490M   0% /dev/shm
/dev/hda6            1012M   42M  919M   5% /tmp
/dev/hda3             9.9G  7.7G  1.7G  83% /usr
/dev/hda2             9.9G  1.8G  7.6G  20% /var
/dev/hdb1              74G   43G   27G  62% /backup
/tmp                 1012M   42M  919M   5% /var/tmp

One possible solution is using GParted: http://gparted.sourceforge.net/
