Some systems behave badly when they completely run out of space. To alleviate this problem, you can set the fallocate_reserve conf value to a number of bytes to "reserve" on each disk. When the disk free space falls at or below this amount, fallocate calls will fail, even if the underlying OS fallocate call would succeed. For example, a fallocate_reserve of 5368709120 (5G) would make all fallocate calls fail, even for zero-byte files, when the disk free space falls under 5G. The default fallocate_reserve is 0, meaning "no reserve", and so the software behaves exactly as it always has unless you set this conf value to something non-zero. Also fixed ring builder's search_devs doc bugs.
