Sammi Chen updated HDDS-12431:
------------------------------
Description:
Currently it uses deltaSizes to record the pre-allocated and pre-deleted bytes
of each volume due to there is selected container to move.
But deltaSizes is not aware by other activities, such as container creation,
container moving command by container balancer. So there is chance that data
volume will be over allocated due to this.
This task aims to use HddsVolume#committedBytes to replace deltaSizes, so that
the space pre-allocated by disk balancer will be fully awared by HddsVolume.
Also MutableVolumeSet#getIdealUsage should consider committedBytes.
