Abstract:
A method of resilvering a plurality of failed devices in a storage pool may include detecting a failure of a first storage device in the storage pool, and determining a plurality of data blocks that are stored on the first storage device. The method may also include sorting the plurality of data blocks into one or more buckets in an order in which the plurality of data blocks are located on the first storage device, and detecting a failure of a second storage device in the storage pool after detecting the failure of the first storage device. The method may further include determining that one or more of the plurality of data blocks are also located on the second storage device, and reusing at least part of the one or more buckets to resilver the second storage device.
