把剩下的空间全给/home时，出现“unable to create the partition .Too big

1.freebsd 分区格式 ufs2 是什么意思，ufs2+s 中的“＋s”是什么意思
2.我在分区的时候先按A 自动分区，然后把/usr修改的小些，但我把剩下的空间全给/home时，出现“unable to create the partition .Too big? ...



1. ufs2 is short for "UNIX File System v2", "+s" means the system partition, load as the root "/";
2. If you did modify your capacity of "/usr" partition, then the left ones will be unused, as magic number of 8, and to combine this block of free space into "/home" partition, you need to delete the original "/home" partition, and make a bigger one to be loaded as the "/home", it's obvious your harddisk cannot be more than such terrible 16YB.

(Re-new)1. SoftUpdate comes to solve the relatively low effeciency of the way to write normal data in buffered way while to write meta data in non-buffered way, it changed the dependency on both kind of data, and re-sort them into a stream in a safe and corrent concequence. So it comes to let FreeBSD fully support async read-write, enchance the performance when operating disk data.
