The man pages suggest what to do when assembling/creating the array.

Since I've _got_ arrays already created, that are auto-assembled using
the info IN mdadm.conf, I'm unclear as to how to change/correct the
name= field.  Can you clarify?

To my other question, http://man-wiki.net/index.php/8:mdadm#DEVICE_NAMES says,

 The standard names for non-partitioned arrays  (the  only  sort  of  md
      array available in 2.4 and earlier) either of

             /dev/mdNN
             /dev/md/NN

      where  NN is a number.  The standard names for partitionable arrays (as
      available from 2.6 onwards) is one of

             /dev/md/dNN
             /dev/md_dNN


Since my arrays are each a single partition (the RAID-10 has LVMs on
the single partition), I guess that the "either of"

             /dev/mdNN
             /dev/md/NN

applies?  And, even if so, why do mdadm --examine & mdadm --detail use
_different_ output formats?
