filesystems - 不同文件系统中的 inode 编号

Question

如果我将目录A（其中有一个文件file_a）挂载到目录B，这两个目录位于不同的文件系统中，两个目录中的file_a会共享相同的inode号吗？

Answer 1

Yes,the inode number of the file will be that of the source directory A. Any new file created in directory B will follow the conventions of the file system in which directory A is present.In Linux terminology,what you're doing is essentially a bind mount.
