In one embodiment, a method includes moving data from an original, unmoved stride from an original array to target stripes of a target stride in a distributed array in response to a determination that all target stripes of the target stride are in a blank state indicating no data is stored therein, delaying movement of the data from the original stride to the target stripes of the target stride in response to a determination that any of the target stripes of the target stride are in an old state indicating unmoved data is stored therein, and moving the data from the original stride to the target stripes of the target stride after delaying and in response to a determination that all the target stripes of the target stride that were in the old state have switched to the blank state.
