Summary[edit | edit source]
The diagram shows a simple subvolume structure, and the relationships between the different sets of keys (grouped here by inode number). Note that the files /incoming and /project/mailbox have been hardlinked together (with ln /incoming /project/mailbox, and that the files /vmbase and /vmimage were made by use of cp --reflink vmbase vmimage. The /vmimage file has been subsequently modified, and the last part of the file rewritten.
Note that in the diagram, the links from DIR_ITEM keys to their respective inodes and links from INODE_REF keys to DIR_INDEX keys are not shown, for clarity.
