ext4：如何恢复分配的 inode

Question

我对 Ubuntu 16.04 上的 ext4 文件系统有一个特殊的问题。我想使用文件管理器“nautilus”将一些目录移动到不同的位置。由于未知原因，交易崩溃了。不，源文件夹是空的，因为目标文件夹也是。

我几乎立即关闭了 PC 并将 HDD 移至不同系统的扩展坞。我使用工具“extundelete”来恢复丢失的数据。不幸的是，这不起作用。

在我看来，整个文件都在那里，但保存数据的 inode 没有“删除”，而是“分配”了，因此 extundelete 无法恢复“未删除”文件。

这是我的命令和输出：

extundelete --inode 4730457 /dev/sdh1
NOTICE: Extended attributes are not restored.

有什么方法、教程或任何提示我可以复制/恢复/修复它吗？

在此先感谢

从来没有找到一个可行的解决方案。我能够使用我的 Linux Mint 上的 testdisk 附带的工具 photorec 来“恢复”文件。

此工具易于使用，并且能够找到所有文件。但是所有文件都已损坏并混合在一起，所以我想它们无论如何都会丢失 - 回到第一格......

如何检查该文件是否真的消失了？通过使用以下命令。

find . -inum 4730457

或

find . -inum <inum>

如果您可以使用此命令找到该文件，则该文件仍然存在。
