Re. creating swap dirs

G'day,

I'm adding some new cache_dirs to my existing (and running cache).

Can someone please tell me

(a) what they recommend for cache_dir sizes (eg: cache_dir ufs
/usr/local/squid/cache 2048 16 256)
(b) whether I can then create these new dirs (squid -z) without losing access
to my squid

Kind Regards,
    Andrew Barnes
