The same as V4.t, with the following modifications:

New fields

  • volume_num stores the number of volumes in the lower layer.
  • mapping_end_poff stores the mapping file size (optional if missing or unknown after a migration from V4).

Changed fields

  • Replaced upgraded_from_v3_to_v4 with generic field upgraded_from to track version upgrades. Note, it is an int option since Version.t option has a bug somewhere in repr that needs further investigation.
