Hello mates, Well i have added to separate hard disks (200GB hd and 500GB hd) and added them in the cache_dir but i noticed that squid Uses the hardisk with MORE disk space and leaves the second one epmty... why? another question lets say the 500GB is full off cache , will squid directly start caching on the Other 200GB hard-disk or will it stop (ERROR no enough space ?) I want to benefit from the 500GB cached objects and want also squid to continue caching on the 200GB hard disk... i have tried this situation on 2 small hard disks , one 10gb and another 20gb, when the 20GB was full , squid stopped and didnt continue to cache on the other 10GB hd, i was reading i saw the read_only option for the cache_dir , is this option the solution for this case? thank you -- IT Manager/Systems Administrator & Security Expert C|EH - CISSP - CCNA - CCSP - CHFI - Linux Professional Network Administrator - Linux Professional Systems Administrator Mobile: 70/ 87 01 78 Email: Xnixguy@xxxxxxxxx
