What you may consider is mdtools. This is a module that you can install
in the 2.0.XX kernels that supports 'Multiple Devices'. What this
entails, is 1 or more devices, in your case hard disks ie: /dev/hda3 and
/dev/hdb1 linked together to form one logical device or /dev/md0
partition. You can install the RAID module aswell, and what this will do,
is distribute the data evenly throughout both devices through the
/dev/md0 partition as opposed to filling up one, and then using the second
device as overflow. It's an option that I use on my news and proxy
servers here. Also, this allows you the seemless addition of a total X
number of devices, be them IDE or SCSI to your /dev/md0 partition. As far
as squid goes, you can mount /dev/md0 /squidcache ; cp -a
/usr/local/squid/cache/* /squidcache ; ln -s /usr/local/squid/cache
/squidcache and voila. 8gigs of cache space, with the seemless
device addition feature built in! =)
