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:

oOne or more systems in the erasure coding topology are inaccessible.

oThe object data cannot be reconstructed from the available chunks.

oNo 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:

oAll systems in the erasure coding topology are accessible.

oThe object data cannot be reconstructed from the available chunks.

oNo system in the topology has a good full copy of the object data.
