WARNING: Extended attributes are not restored.
WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible. You should unmount the
file system and check it with fsck before using extundelete.
Would you like to continue? (y/n)

ok,这样就恢复成功了。
当然文件不能保证一定恢复成功，我的另外一个文件恢复出来是乱码，还有一个文件报错找不到inode.
