1780 We want to select which directory to use for
1781 the next file source to be created. Ideally,
1782 we'd like to use a round-robin process so as to
1783 get maximum performance benefits from splitting
1784 the files across multiple disks.
1786 However, in situations without much diskspace, an
1787 RR approach may end up filling up a filesystem
1788 with new files while others still have space.
1789 Its therefore important to pay some attention to
1790 the freespace in the filesystem holding each
1791 directory as well. However, if we did that by
1792 itself, we'd keep creating new files in the file
1793 system with the most space until it was as full
1794 as all others, thus negating any performance
1795 benefits of this RAID-1 like approach.
1797 So, we use a user-configurable space threshold. If
1798 there are at least 2 filesystems with more than this
1799 much space available, we use RR selection between them.
1800 If not, then we pick the filesystem with the most space.
