2291 We want to select which directory to use for
2292 the next file source to be created. Ideally,
2293 we'd like to use a round-robin process so as to
2294 get maximum performance benefits from splitting
2295 the files across multiple disks.
2297 However, in situations without much diskspace, an
2298 RR approach may end up filling up a filesystem
2299 with new files while others still have space.
2300 Its therefore important to pay some attention to
2301 the freespace in the filesystem holding each
2302 directory as well. However, if we did that by
2303 itself, we'd keep creating new files in the file
2304 system with the most space until it was as full
2305 as all others, thus negating any performance
2306 benefits of this RAID-1 like approach.
2308 So, we use a user-configurable space threshold. If
2309 there are at least 2 filesystems with more than this
2310 much space available, we use RR selection between them.
2311 If not, then we pick the filesystem with the most space.
