> This is related to HDDS-1511
> Space tracking for Open Containers (committed space in the volume) relies on
> usedBytes in the Container state. usedBytes is not persisted for every update
> (chunkWrite). So on a node restart the value is stale.
> The proposal is to:
> iterate the block DB for each open container during startup and compute the
> used space.
> The block DB process will be accelerated by spawning executors for each
> container.
> This process will be carried out as part of building the container set during
> startup.
