ABSTRACT:
A method for storing a data block in a storage pool, including receiving a write operation for the data block, writing the data block into the storage pool, determining a first indirect block to store in the storage pool, wherein the first indirect block references the data block, writing the first indirect block to a first location in the storage pool, creating a copy of the first indirect block, and writing the copy of first indirect block to a second location in the storage pool.
