When any container operation is going on, it must reserve committed space (ie space is may consume once container is build). With this, need for extra container space may be not be required. Will re-check EC container rebuild for committed space or not to fix specific part, And any possibility of crossing min-avaialable space. -- This is an automated message from the Apache Git Service.
