from the cache_dir directive regarding coss:

        block-size=n defines the "block size" for COSS cache_dir's.
        Squid uses file numbers as block numbers. Since file numbers
        are limited to 24 bits, the block size determines the maximum
        size of the COSS partition. The default is 512 bytes, which
        leads to a maximum cache_dir size of 512<<24, or 8 GB. Note
        you should not change the COSS block size after Squid
        has written some objects to the cache_dir.
