ABSTRACT:
In general, the invention relates to a method for storing data. The method includes receiving an Input/Output (I/O) request to store data in a storage pool, determining whether the I/O request is a resilvering I/O request, if the I/O request is a resilvering I/O request: associating the I/O request with a first deadline, wherein the first deadline is associated with a low priority, and determining the quantized deadline for the I/O request using the first deadline. If the I/O request is not the resilvering I/O request: associating the I/O request with a second deadline, determining the quantized deadline for the I/O request using the second deadline, placing the I/O request in the I/O queue using the quantized deadline, and issuing the I/O request to the storage pool using the I/O queue.
