H A Draid5-cache.rst7 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
27 and parity don't match. The reason is that a stripe write involves several RAID
