I'm not an expert on this filesystem, but on other filesystems that extra 5-10% is used by the filesystem to minimize fragmentation. On HP-UX there is a definite performance impact when this is made too small. Can a filesystem guru clue us in on the right rule of thumb? Is it 10% or is there a particular total size (e.g. 500mb) above which the extra space is wasted? I'm going to do some big raids this summer and 5% of 100+GB starts to add up.
