Unavailable and irreparable erasure-coded objects

The status of an erasure-coded object can differ among the systems in an erasure coding topology:

  • An erasure-coded object is unavailable on a system if all of these are true:
    • One or more systems in the erasure coding topology are inaccessible.The object data cannot be reconstructed from the available chunks.
    • No accessible system has a good full copy of the object data.
  • An erasure-coded object is irreparable on a system if all of these are true:
    • All systems in the erasure coding topology are accessible.
    • The object data cannot be reconstructed from the available chunks.
    • No system in the topology has a good full copy of the object data.
