+checkarray notes
+================
+
+checkarray will run parity checks across all your redundant arrays. By
+default, it is configured to run on the first Sunday of each month, at 01:06
+in the morning. This is realised by asking cron to wake up every Sunday with
+/etc/cron.d/mdadm, but then only running the script when the day of the month
+is less than or equal to 7. See #380425.
+
+'check' is a read-only operation, even though the kernel logs may suggest
+otherwise.
+
+If while reading, a read error occurs, the check will trigger the normal
+response to read errors which is to generate the 'correct' data and try to
+write that out - so it is possible that a 'check' will trigger a write.
+However in the absence of read errors it is read-only.

+12. change the preferred minor of a RAID array
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+    # you need to manually assemble the array to change the preferred minor
+    # if you manually assemble, the superblock will be updated to reflect
+    # the preferred minor as you indicate with the assembly.
+    # for example, to set the preferred minor to 4:
+    mdadm --assemble /dev/md4 /dev/sd[abc]1
+
+    # if this does not work (you need a 2.6 kernel), try:
+    mdadm --assemble --update super-minor /dev/md4 /dev/sd[abc]1
