Abstract
A system and method for reading file blocks includes reading an inode associated with the file from the file system, the inode including one or more first block pointers, determining a height of a file tree associated with the file, and determining whether a value of a second block pointer selected from the one or more first block pointers is consistent with the file having been stored using a block allocation pattern. When the value of the second block pointer is consistent with the file having been stored using the block allocation pattern the method further includes pre-fetching a plurality of file blocks based on the block allocation pattern, verifying that the pre-fetched file blocks are consistent with the file tree, and retrieving one or more data blocks of the file. In some examples, the block allocation pattern corresponds to the file being stored in streaming order to consecutively and contiguously located blocks.
