Can you elaborate? Assuming levels=1 and two disks: proxy_cache_path /path/to/cache levels=1 ... $ cd /path/to/cache $ for i in 0 1 2 3 4 5 6 7; do mkdir /disk1/$i; ln -s /disk1/$i .; done; $ for i in 8 9 a b c d e f; do mkdir /disk2/$i; ln -s /disk2/$i .; done; -- Maxim Dounin http://nginx.org/en/donation.html _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
