Inode

基本解释

Though it works in client/server inode, FTP has unique feature:doubly linked.
ftp雖然採用客戶／服務器工作模式．但有其鮮明的特色：雙重連接。
For example, since a file's permissions are contained within its inode, both links have the same permissions.
例如，因爲一個文件的權限包含在其節點內，所以兩個連接具有相同的權限。
Without allocation groups, the XFS filesystem code could become a performance bottleneck, forcing IO-hungry processes to "get in line" to make inode modifications or performing other kinds of metadata-intensive operations.
如果不使用分配組,XFS文件系統代碼可能成爲一種性能瓶頸,迫使大量需求IO的進程“排隊”來使索引節點進行脩改或執行其它種類的元數據密集操作。
Each file and directory is an individual INODE(Ex. A directory named test with 5 files in it adds up to 6 INODES).
每個文件夾都算一個獨立的INODE（例如：一個含5個文件的文件夾，那麽就算6個INODES）
