Abstract
A method of resilvering a plurality of failed devices in storage pools includes detecting a failure of a first storage device in a storage pool, identifying data blocks that were stored on the first storage device that are also stored on other storage devices, and resilvering the first storage device by transferring the data blocks from the other storage devices. While resilvering the first storage device, the method includes detecting a failure of a second storage device in the storage pool, identifying a subset of the data blocks that were stored on the first storage device that were also stored on the second storage device, and reusing a set of sequential I/O commands to resilver at least a portion of the second storage device with the subset of the data blocks.
