Hi, Perhaps I am rushing all this and ending up missing something crucial that I should understand. Allow me to ask anyway. This is what I am doing (and missing the point in the process!): dd if=/dev/zero bs=1048576 count=5120 of=/shared/squid-coss/coss1 dd if=/dev/zero bs=1048576 count=5120 of=/shared/squid-coss/coss2 cache_dir coss /shared/squid-coss/coss1 5 max-size=131072 cache_dir coss /shared/squid-coss/coss2 5 max-size=1048575 cache_swap_log /usr/local/squid/logs/%s Squid will not start, spewing the following: 2006/10/21 11:38:10| COSS: max disk fileno is 10240 2006/10/21 11:38:10| COSS: number of stripes: 5 of 1048576 bytes each 2006/10/21 11:38:10| COSS: number of memory-only stripes 10 of 1048576 bytes each 2006/10/21 11:38:10| COSS: max disk fileno is 10240 2006/10/21 11:38:10| COSS: number of stripes: 5 of 1048576 bytes each 2006/10/21 11:38:10| COSS: number of memory-only stripes 10 of 1048576 bytes each Please explain to me what I have missed.
