I consider that the data on the broken chunk server can be divided into 2 different types.

  • First, the goal of the lost data is 1.
  • Second, the goal of the lost data is larger than 1.

If it is the first circumstance, the data can not be repaired.

If it is the second circumstnce, the lost can be found in other chunk server. you can add a new chunk server in to the mfs cluster, the master can decide the replication between the chunk servers.
