Abstract
In one embodiment, a method includes iteratively selecting an original, unmoved stride from an original array until all original strides have been moved, determining a target stride location in a distributed array, determining a state of the target stride from the following states: an old state indicating unmoved data, a blank state indicating no data, and a new state indicating migrated data, determining that all target stripes are blank, moving data from the original stride to the target stripes when all the target stripes are blank, delaying the moving of the data from the original stride to the target stripes in the target stride when any of the target stripes of the target stride are in the old state and waiting until all the target stripes of the target stride are in the blank state, and determining that all original strides from the original array have been moved.
