Missing or lost essential attribute values can lead to data inconsistencies. Sometimes missing or lost values are due to human error (deleting a value or an object when not supposed to), but they can also be a result of system failure (such as time synchronization error or communication issues). The following sections examine the causes and possible solutions to the following situations:

• Unknown objects

• Renamed objects

• Replica ring inconsistency

• Replica inconsistency

• Stuck obituaries
