H A Draid5-ppl.rst6 addressed by PPL is that after a dirty shutdown, parity of a particular stripe
15 Partial parity for a write operation is the XOR of stripe data chunks not
18 the stripe, consistent with its state before the write operation, regardless of
20 this stripe is missing, this updated parity can be used to recover its
29 stripe. It does not require a dedicated journaling drive. Write performance is
36 silent data corruption. If a dirty disk of a stripe is lost, no PPL recovery is
37 performed for this stripe (parity is not updated). So it is possible to have
38 arbitrary data in the written part of a stripe if that disk is lost. In such
H A Draid5-cache.rst27 and parity don't match. The reason is that a stripe write involves several RAID
