Adam Litke has uploaded a new change for review. Change subject: Do not extend volume beyond truesize ......................................................................
Do not extend volume beyond truesize When calling getNextVolumeSize on a volume that is close to fully allocated, the function can return a value larger than the volume's real capacity. Add an explicit ceiling to prevent this.
