新改进 FreeBSD: UFS with Softupdates, Journaling

没本

从 OSNews 作者：donotreply@osnews.com ()

Today Jeff Roberson committed his patches to FreeBSD 9 for adding journaling to UFS. No more background fsck after unclean shutdowns! This is a major landmark in the history of UFS, with 11000 new lines of code (and about 2000 removed). Much of the work was done in collaboration with Kirk McKusick, the original author of FFS and Softupdates, under sponsorship form Yahoo!, Juniper and iXsystems. Jeff's blog contains quite a lot of technical information of his work. There's also information on the FreeBSD mailing lists.

其实直接都换成ZFS不就新了，还用这样新瓶装旧酒吗。

ZFS 对硬件要求比较高，而且还需要配置。

很久以前就可以在/usr文件系统使用UFS+S啦。

你没看明白吧，这次的亮点是日志文件系统(Journaling)。相当于ext3比之ext2。
