也就是說，不要重新做分區，把現有資料的 ext3 分區，直接升級或轉換到 ext4！

不知道該怎麼做，或是沒有辦法，得一定要重做分區。

請老鳥指點了

可以直接转换

题目写错了。呵呵

我就说吗 本来就是4了还要转成4 什么逻辑 呵呵。

謝謝 lerosua 提醒，已經改好了!

3.2. Migrate existing Ext3 filesystems to Ext4

You need to use the tune2fs and fsck tools in the filesystem, and that filesystem needs to be unmounted. Run:

*

tune2fs -O extents,uninit_bg,dir_index /dev/yourfilesystem

After running this command you MUST run fsck. If you don't do it, Ext4 WILL NOT MOUNT your filesystem. This fsck run is needed to return the filesystem to a consistent state. It WILL tell you that it finds checksum errors in the group descriptors - it's expected, and it's exactly what it needs to be rebuilt to be able to mount it as Ext4, so don't get surprised by them. Since each time it finds one of those errors it asks you what to do, always say YES. If you don't want to be asked, add the "-p" parameter to the fsck command, it means "automatic repair":

*

fsck -pf /dev/yourfilesystem
