For non-full-stripe writes, MD must read old data before the new parity 54 can be calculated. These synchronous reads hurt write throughput. Some writes 90 order in which MD writes data to cache disk and RAID disks. Specifically, in 91 write-through mode, MD calculates parity for IO data, writes both IO data and 92 parity to the log, writes the data and parity to RAID disks after the data and 96 In write-back mode, MD writes IO data to the log and reports IO completion. The 110 they are discarded too. MD then loads valid data and writes them to RAID disks
