摘要： Placement of object replicas in a distributed storage system includes, at a first instance, opening a journal for storage of object chunks. Each journal is associated with a single placement policy. An object is received, which comprises a chunk. The object has a placement policy, and the chunk comprises a plurality of storage blocks. The blocks are stored in a journal that matches the placement policy. Global metadata for the object is stored, which includes a list of chunks for the object. Local metadata for the chunk is stored, which includes a block list identifying each block of the plurality of blocks. The local metadata is associated with the journal. The journal is later closed. The journal is subsequently replicated to a second instance according to the placement policy. The global metadata is updated to reflect the replication, whereas the local metadata is unchanged by the replication.
