Do you really want your OS on a striped partition? That doubles your
chances of losing your OS!

My current server has five spindles - 2 in a RAID1 config for the OS and
3 as JBODs for the cache. If a cache disk dies then I remove the
cache_dir entry for it until the disk is replaced and then reinstate it
(after a squid -z).

I'm not going to worry about the contents of those disks.

HTH,
