The invention discloses a subsection recombination method. A plurality of subsections for recombination are selected and meet the condition that at most one data strip located at a same data storage node contains valid data; and the plurality of data strips containing the valid data are taken as data of the new subsection data strips, verification data of the verification strips are generated forthe data of the new subsection data strips, and the verification data of the verification strips is stored to the corresponding storage verification storage nodes. 本方案公开了一种分条重组的方法，选择进行重组的多个分条满足位于相同数据存储节点的数据条带最多有一个数据条带包含有效数据，将多个分条包含有效数据的数据条带作为新的分条的数据条带的数据，为新的分条的数据条带的数据生成校验条带的校验数据，并将校验条带的校验数据存储到对应的存校验存储节点。
