Abstract: In one example, a method may include receiving a write operation corresponding to a portion of a data chunk stored at a first storage location in a write-in-place file system. The write-in-place file system may include encoded data chunks and unencoded data chunks. The method may include determining whether the data chunk is an encoded data chunk based on metadata associated with the data chunk, modifying the data chunk based on the write operation, and selectively performing a redirect-on-write operation on the modified data chunk based on the determination.
