RE: [squid-users] File system recommendations for squid cache.

The OS is Linux 2.4.29 (Debian 3.0_R4)
What is the recommended size of each cache_dir (disk)?

Squid Cache: Version 2.5.STABLE7
configure options: --bindir=/usr/sbin --sbindir=/usr/sbin
--localstatedir=/var/spool/squid --sysconfdir=/etc/squid
--libexecdir=/usr/lib/squid --enable-linux-netfilter
--enable-cache-digests --enable-poll --enable-delay-pools
--enable-underscores --enable-useragent-log --enable-storeio=diskd,ufs
--enable-snmp

cache_dir diskd /var/spool/squid 65536 64 1024

Still, with several smaller independent disks for the cache_dirs, what
filesystem is recommended for this use?

Thanks so far...
