索引节点通常不大,对于一个文件系统而言,索引节点的数量表示文件系统中可以拥有的最大文件数。 到目前为止,我们的文件系统有了数据块(D)和索引节点(I),但是还缺少一种重要组件来跟踪索引节点或数据块是空闲还是已分配,这种分配结构(allocation structures)是任何文件系统中必不可少的。 跟踪分配方法很有多,可以使用f...

11. List and briefly define three file allocation methods? Contiguous allocation: a single contiguous set of blocks is allocated to a file at the time of file creation. Chained allocation: allocation is on an individual block basis.Each block contains a pointer to the next block in the chain...
File system and methods for performing file create and open operations with efficient storage allocationA client computer system of a cluster may send a request to create a file in a cluster file system. A server may create a file in response to the information and allocate space in a ...
In a round-robin allocation, files are created in a round-robin fashion on each slice or striped group. The maximum performance for one file will be the speed of a slice or striped group. For more information about file allocation methods, see theOracle Hierarchical Storage Manager and Storage...
