为何同一个分区使用不同分区格式，显示容量大小不同？

刚把主分区换成了ext4，原来是jfs，其实感觉没多大差别。

ext4 is Fourth extended file system, deriving from ext2 and ext3. It has a  journal, but not jfs!

ps: jfs is a type of journal file system developed by IBM,
howerver, it already stops going on.

他是说他以前用的jfs...

应该就是inode和日志的问题, 楼主可以试着关掉日志看看

有惨痛丢失数据的经历，这里劝告楼主，宁可花50%的空间用于备份，也不要为了那区区5%去牺牲数据的安全。
