    摘要: A method and apparatus are provided for pre-allocating non-initialized blocks of data in a file system. Each file contains a primary i-node to maintain file metadata. A secondary i-node is created and associated with the primary i-node. The secondary i-node contains non-initialized data blocks, and the primary i-node contains valid and initialized data blocks. A write operation to a non-initialized data block in a pre-allocated range stored in the secondary i-node directs the data block from the secondary i-node to the primary i-node.
