H A D	raid5-ppl.rst	6 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 D	raid5-cache.rst	27 and parity don't match. The reason is that a stripe write involves several RAID 52 write. If a write crosses all RAID disks of a stripe, we call it full-stripe 53 write. For non-full-stripe writes, MD must read old data before the new parity 57 RAID disks only after the data becomes a full stripe write. This will 101 release the memory cache. The flush conditions could be stripe becomes a full 102 stripe write, free cache disk space is low or free in-kernel memory cache space 107 data and data.
