Abstract
A computer readable medium includes executable instructions for resilvering a hierarchical block tree in a storage pool. Resilvering the hierarchical block tree involves traversing a branch of the hierarchical block tree only if a birth time of a parent block of the branch is greater than or equal to a lowest birth time on a dirty time log (DTL). Resilvering the hierarchical block tree further involves resilvering a child block in the branch only if the DTL comprises a birth time of the child block.
