To allow the fastest switching from the passive-standby to active mode, the runtime metadata must be kept 100% synced with the metadata on the drive and in the RAM thus recovery is required after each collision section update. To avoid long-lasting recovering of all the cachelines each time the collision section is being updated, the passive update procedure recovers only those which have its MD entries on the updated pages.
