[robert k Wild]

thanks Ged, i will look into this def

i found out what was eating all my space on sdb1, i ran the "du -sh"
command on all dirs, it was my squid logs, so i just did this and reloaded
squid

echo "" > /usr/local/squid/var/logs/access.log

echo "" > /usr/local/squid/var/logs/cache.log

/usr/local/squid/sbin/squid -k reconfigure
