Detailed Description

On-disk structures for erasure coding recovery data.

These packed structures describe the Erasure Coding Map Block (ECMB), stripe group descriptors, per-block entries within stripes, and the recovery footer written at the very end of the file.

All integer fields are stored little-endian on disk.

Definition in file erasure.h.
