2139 We want to select which directory to use for
2140 the next file source to be created. Ideally,
2141 we'd like to use a round-robin process so as to
2142 get maximum performance benefits from splitting
2143 the files across multiple disks.
2145 However, in situations without much diskspace, an
2146 RR approach may end up filling up a filesystem
2147 with new files while others still have space.
2148 Its therefore important to pay some attention to
2149 the freespace in the filesystem holding each
2150 directory as well. However, if we did that by
2151 itself, we'd keep creating new files in the file
2152 system with the most space until it was as full
2153 as all others, thus negating any performance
2154 benefits of this RAID-1 like approach.
2156 So, we use a user-configurable space threshold. If
2157 there are at least 2 filesystems with more than this
2158 much space available, we use RR selection between them.
2159 If not, then we pick the filesystem with the most space.
