Can I mount var off of /usr? Here is a slightly simpler solution than what Anders proposed that may work for you. Find out which sub-directories of /var are the disk space consumers: du -d1 /var | sort -rn | head That will list the top ten. This method assumes you have only one or two large directories, and that moving them would yield a substantial reduction in /var disk space usage. Let's assume that /var/log and /var/db are the top two directories. Shutdown to single-user mode. Stop any daemons like syslog, sendmail, etc. that might write to /var/log or /var/db, since you will be working with those two directories. cd into /var and move the log sub-directory onto the /usr mount point, and then create a symlink to make /var/log redirect to the new location on /usr: cd /var mv log /usr/var-log ln -s /usr/var-log log Repeat for /var/db: mv db /usr/var-db ln -s /usr/var-db db Reboot. This procedure eliminates the need to mess with your disklabel or your fstab. BTW, it looks like your / partition is a bit crowded, also. :) Jim
