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
10 refer to mdadm manual for details. By default (RAID array starts), the cache is
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
