A Draid5-ppl.rst6 addressed by PPL is that after a dirty shutdown, parity of a particular stripe

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