2672 We want to select which directory to use for
2673 the next file source to be created. Ideally,
2674 we'd like to use a round-robin process so as to
2675 get maximum performance benefits from splitting
2676 the files across multiple disks.
2678 However, in situations without much diskspace, an
2679 RR approach may end up filling up a filesystem
2680 with new files while others still have space.
2681 Its therefore important to pay some attention to
2682 the freespace in the filesystem holding each
2683 directory as well. However, if we did that by
2684 itself, we'd keep creating new files in the file
2685 system with the most space until it was as full
2686 as all others, thus negating any performance
2687 benefits of this RAID-1 like approach.
2689 So, we use a user-configurable space threshold. If
2690 there are at least 2 filesystems with more than this
2691 much space available, we use RR selection between them.
2692 If not, then we pick the filesystem with the most space.
