不知道該怎麼做，或是沒有辦法，得一定要重做分區。

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！

可以直接转换

要理解递归，首先要理解递归。
地球人都知道，理论上，理论跟实际是没有差别的，但实际上，理论跟实际的差别是相当大滴。

Re: 菜鳥詢問：ext3 可以轉換成為 ext4 嗎？
剛剛找到這訊息............
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
