Abstract
A system and method for enabling write operations to files undergoing write allocation is provided. The system and method generate a shadow state entry of metadata associated with an inode of the file upon receipt of a write operation. During the write allocation process for the inode, the shadow state information is merged with the data stored in the inode to be written to disk.
