A method for ensuring the integrity of a storage device comprising: initiating a data mover operation to move an object to the storage device; deriving an extent list describing destination blocks on the storage device, wherein the destination blocks comprise a location to which the object is being moved by the data mover operation; transmitting the extent list to a disk array; verifying the extent list; monitoring for a write request from an application server during the data mover operation; if a write request is detected during the monitoring for the write request, stalling the write request and requesting a termination of the data mover operation; terminating the data mover operation in response to the requesting the termination of the data mover operation; completing the write request after the termination of the data mover operation; releasing the extent list at the disk array after the completing the write request; and re-verifying the extent list after the releasing the extent list.
