H A D	raid5-cache.rst	6 disks. The role of RAID disks isn't changed with the cache disk. The cache disk 7 caches data to the RAID disks. The cache can be in write-through (supported 28 disks and it's possible the writes don't hit all RAID disks yet before the 35 is safe on the cache disk, the data will be flushed onto RAID disks. The 40 filesystems) after the data is safe on RAID disks, so cache disk failure 52 write. If a write crosses all RAID disks of a stripe, we call it full-stripe 57 RAID disks only after the data becomes a full stripe write. This will 63 disks later after specific conditions met. So cache disk failure will cause 90 order in which MD writes data to cache disk and RAID disks. Specifically, in 92 parity to the log, writes the data and parity to RAID disks after the data and [all …]
H A D	raid5-ppl.rst	7 may become inconsistent with data on other member disks. If the array is also 9 disks is missing. This can lead to silent data corruption when rebuilding the 19 which chunk writes have completed. If one of the not modified data disks of 22 unclean shutdown and all disks are available, eliminating the need to resync 27 parity are dispatched to disks. PPL is a distributed log - it is stored on 44 There is a limitation of maximum 64 disks in the array for PPL. It allows to 45 keep data structures and implementation simple. RAID5 arrays with so many disks 46 are not likely due to high risk of multiple disks failure. Such restriction
