H A D	raid5-cache.rst	5 Raid 4/5/6 could include an extra disk for data cache besides normal RAID 7 caches data to the RAID disks. The cache can be in write-through (supported 8 since 4.4) or write-back mode (supported since 4.10). mdadm (supported since 9 3.4) has a new option '--write-journal' to create array with cache. Please 11 in write-through mode. A user can switch it to write-back mode by:: 13 echo "write-back" > /sys/block/md0/md/journal_mode 15 And switch it back to write-through mode by:: 17 echo "write-through" > /sys/block/md0/md/journal_mode 22 write-through mode 25 This mode mainly fixes the 'write hole' issue. For RAID 4/5/6 array, an unclean [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 10 array or using it is as degraded - data calculated from parity for array blocks 11 that have not been touched by a write request during the unclean shutdown can 12 be incorrect. Such condition is known as the RAID5 Write Hole. Because of 15 Partial parity for a write operation is the XOR of stripe data chunks not 16 modified by this write. It is just enough data needed for recovering from the 17 write hole. XORing partial parity with the modified chunks produces parity for 18 the stripe, consistent with its state before the write operation, regardless of 19 which chunk writes have completed. If one of the not modified data disks of [all …]
