That's not how extents work. What you are describing is a large block granularity, not extents-based allocation. There is no reason why the next allocation can't happen like this: [X][ ][ ][ ][ ][ ][ ][ ][ ][ ][ ][ ] [X][X][X][X][ ][ ][ ][ ][ ][ ][ ][ ] [X][X][X][X][X][X][X][X][A][A][A][A] [X][X][ ][ ][ ][ ][ ][ ][ ][ ][ ][ ] [X][X][X][ ][ ][ ][ ][ ][ ][ ][ ][ ] [-][-][-][-][-][-][-][-][-][-][-][-] [-][-][-][-][-][-][-][-][-][-][-][-]
That was pretty much my question, ty very much :) greets! aL
