A Dnand_ecc.rst33 columns. The parity used is even parity which means that the parity bit = 1
34 if the data over which the parity is calculated is 1 and the parity bit = 0
59 cp is my abbreviation for column parity, rp for row parity.
114 nicer picture.(but they use line parity as term where I use row parity)

A Draid5-ppl.rst6 addressed by PPL is that after a dirty shutdown, parity of a particular stripe
8 in degraded state, there is no way to recalculate parity, because one of the
10 array or using it is as degraded - data calculated from parity for array blocks
15 Partial parity for a write operation is the XOR of stripe data chunks not

26 When handling a write request PPL writes partial parity before new data and
27 parity are dispatched to disks. PPL is a distributed log - it is stored on
28 array member drives in the metadata area, on the parity drive of a particular

A Draid5-cache.rst27 and parity don't match. The reason is that a stripe write involves several RAID

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
93 parity is settled down in log and finally the IO is finished. Read just reads
99 MD will calculate parity for the data and write parity into the log. After this
